However, easily the best way to enjoy smart home technology is to have them all connected in some way, allowing you to gain complete control over your home.

Many people make use of smart assistants like Alexa, Google Nest, or Apple Siri, however easily one of the best ways to control and connect all of your smart devices is to use HomeKit!

However, the trouble with HomeKit is that it is an application that is designed entirely for use on Apple products like iPhones, iPads, and Mac computers. Kind of like Apple’s version of Home Assistant.

That being said – there is a way to use Homebridge outside of the Apple ecosystem and I’d say you’ve already guessed this – but it is with the power of your Raspberry Pi!

What Is Homebridge?

Before we find out how to access HomeKit via a Raspberry Pi, it is worth looking at what Homebridge is, and how its services tie in with HomeKit.

Put simply, Homebridge is a private server that can be used on devices that aren’t produced by Apple and emulates the infrastructure of the iOS operating system to allow users to connect to HomeKit, to allow them to control their smart appliances from devices like a Raspberry Pi.

How Do You Install Homebridge On Raspberry Pi?

Before we take a look at how exactly to install Homebridge onto your Raspberry Pi device, we will need to make sure that we have everything that we need in order to do it all correctly.

First, you will want to make sure that you have your Raspberry Pi computer close at hand.

Preferably, you will want to make sure that you have a Raspberry Pi 3B+ or better, as such versions of the device will be able to better process your commands.

You will also want to make sure that you have access to a MicroSD card with plenty of space, as this is where you will be installing the application to be used by the device.

Don’t worry too much though, as the application does not take up too much space, and does not require too much processing power.

You will also need the official Homebridge image to be installed on Raspberry Pi, as well as a program like the Raspberry Pi Imager that allows you to convert the images into executable applications.

Make sure you also have access to a computer that is connected to the internet to help you to carry everything out correctly.

Step 1 – Prep Your Raspberry Pi

Whenever you plan to install new software on your Raspberry Pi device, you should always make a point of updating the device first, to ensure that it is ready. Head to the command terminal and type in:

“Sudo-apt-get update
Sudo-apt-get upgrade”

Hit enter on the keyboard, and then restart the Raspberry Pi to update it.

Step 2 – Download The Image

Head to your computer, and download the Homebridge Raspberry Pi image from the Homebridge official website.

Once you have downloaded the imager, grab your MicroSD card, insert it into your computer, and then head to your chosen imager. We recommend making use of the Raspberry Pi Imager.

Follow the instructions on the imager and set the image to install to the MicroSD card.

Step 3 – Open Your Raspberry Pi

Now that you have installed the application onto your MicroSD card, simply insert it back into the Raspberry Pi, and activate the device.

Step 4 – Get Started With Homebridge

Now that you have Homebridge installed on your Raspberry Pi, you will want to head to your computer to start customizing your experience with Homebridge.

Head to the Homebridge page at ‘homebridge.local’ on your web browser. You may be prompted to log in, which can be done by using the username ‘admin’, and the password ‘admin’.

Feel free to change your login details for the application using this web page.

Step 5 – Use Plugins

Look toward the top of the Homebridge webpage, and you should notice a number of buttons to choose from. Click the ‘Plugins’ option amongst those.

Plugins are what Homebridge uses to bridge all of your smart devices together. Each of the plugins can be individually searched for by using the search bar at the top of the plugin page.

Plugins are created by other Homebridge users, and as such, some are better than others.

Thus, when searching amongst the plugins, make sure to look for those that have been verified, as they have been personally reviewed by the Homebridge team for quality assurance.

Installing plugins from this menu is very easy, and while each plugin may have specific requirements for installation, most are very simple by following the on-screen instructions.

Each plugin can also be looked further into by clicking on the wrench icon beside each one, which allows you to look at specific information about each plugin and change certain settings.

Step 6 – Connect Homebridge To HomeKit

Head to your iOS device, and open up the HomeKit app. From here, you can tap the ‘Add accessory’ button, and then scan the QR code that shows up on the Homebridge homepage on your computer.

This will cause the two applications to automatically be linked.

To Wrap Up

There we have it. Installing Homebridge onto the Raspberry Pi is not a difficult procedure at all, and can be done easily by following our guide!

Home automation is no longer a concept of the future. With the help of smart home devices, you can streamline your routine and free up your time, from turning on the lights to regulating the thermostat. According to statistics by Mediapost, the majority (69%) of houses in the US own at least one smart-home device now.

And home automation is now more affordable than ever thanks to Raspberry Pi Z-Wave! Modern technology makes it simple to manage your home from anywhere, at any time through wireless systems. 

In this article, we will explore how to set up your Raspberry Pi Z Wave and use it to control devices in your smart home.

We will be using an open-source home automation software called Home Assistant to connect and monitor the Z-wave devices with Raspberry Pi. 

Let’s dive in.

1.) Components You Will Need:

To set up a Raspberry Pi Z-Wave system, you will be needing:

• A Raspberry Pi
• USB-C power cable with adapter
• An Ethernet cable
• An SD card and SD card reader for RPi
• Z-wave USB dongle
• Smart home appliances
• RPi case, preferably one that has cooling capabilities

2.) Flashing the SD card:

In order to get the home assistant image onto the SD card, you need a tool named “balena Etcher”.

Balena Etcher makes it possible for Raspberry Pi users to create a bootable SD card for their devices. And, the good news is, this tool is supported cross platform. (Windows, Linux and MacOS ).

To get started with it:

• Put the SD card into the SD card reader and plug that into your PC
• Next, go to google and search for “balena Etcher’’
• Click on the top link and press download Etcher

3.) Home Assistant for Raspberry Pi Z Wave:

Once you have downloaded the Balena Etcher software:

• Search for “home assistant for Raspberry Pi’’ on Google and click the link that gives information regarding the procedure to download home assistant on RPi
• Scroll down to the website to where the URL for the home assistant installation file is given
• Copy the URL for the 64-bit version of whichever Raspberry Pi model you are using

4.) Linking Balena Etcher with Home Assistant:

• Once Balena Etcher software is downloaded, open it, and click “Flash from URL”
• Paste the Home Assistant URL that you just copied in the previous step and click “ok”

Now Balena Etcher will download that home assistant image and will ask you to select the target location that it should be flashed to. 

To select the target location:

• Click on “select target’’
• Then choose the SD card that you had connected to your computer earlier
• Now click on “flash’’ and wait for a few minutes

Once done, you will get a notification that flashing is completed, and then you can remove the SD card from your PC.

5.) Assembly and Startup

Now it’s time to assemble the Raspberry Pi. 

This is a crucial step in making sure that the Raspberry Pi operates at optimal temperatures, preventing any overheating issues that could compromise the performance and stability of the device.

• First, insert the flashed SD card to the RPi and attach the ethernet cable to the Ethernet port
• Then insert the USB-C power cable to the power port

This will power up your Raspberry Pi. On your PC browser, navigate homeassistant.local:8123. Alternatively, you can login as http://xxxx:8123 (where xxxx is your Raspberry Pi IP address). 

Note: If you don’t know the RPi IP address, log into your router and find it there.

• Once you are successful with navigating your IP address, you are going to see a screen indicating that the home assistant is starting for the first time 
• Wait until it is complete and then create a username and password following the prompts
• Once logged in, it is going to ask you for some other basic information, fill it out and click next 

TopTip: It is highly recommended to encase your Raspberry Pi device in its protective casing, as this not only offers additional durability but also has cooling capabilities that aid in the transfer of heat away from the central processing unit (CPU) and towards the aluminium casing. 

6.) Adding Raspberry Pi Z-Wave Integrations

Congratulations – you’re almost there! With just one more step, you’ll have your home assistant up and running on your Raspberry Pi. This final step is essential, as it will ensure that your home assistant operates smoothly and efficiently. 

The Z-wave features of your smart home devices are enabled and controlled through the Z-wave smart hub gateway.  With Z-Wave integrations, you are able to control a Z-Wave network using the Z-Wave JS driver. 

To setup Raspberry Pi Z-Wave communication you have to:

• Plug the Z-wave USB stick into your Raspberry Pi USB port
• Go to “Configuration” on the home assistant screen and press “Integrations”
• On the Integrations page, you should see that if the USB is recognized as a device for Z-Wave JS
• Press the figure and confirm if you want to use this device as the Z-wave coordinator

We prefer the Zooz 700 Series Z Wave USB stick, however, you’ll find a number of different sticks that will do the job such as the Aeotec Z-stick Gen 5, Aeotec Z-Stick 7, Zooz ZST10, GoControl HUSBZB-1 etc.

7.) Adding Devices to the Z-Wave Network

There are a large number of devices that can be connected through Z-wave, for example, lights, bulbs, weather monitors, daylight sensors and more.

• In the “Devices and Services” page click on “Configure” under Z-Wave JS integration, then follow the instructions that came with the device you want to add to trigger parent mode
• Click on “add device” and give it a few seconds for the integration to find the Z-Wave device
• If the device is detected, it will ask you to enter the pin number to verify the device’s specific key. (it is available on the device or on the manual that came with it)
• Click on “submit”

The device will now be added successfully. Once added, click on “view device” to see all the different data you can get from that device. You can also add more devices using these same steps. 

And you’re done! You have successfully set up Z-Wave with your Raspberry Pi. 

Key Takeaways

• Smart home devices can help streamline your routine and save time by allowing you to control various aspects of your home from anywhere.
• The Raspberry Pi Z-Wave is an affordable way to set up a smart home system.
• To get started with the Raspberry Pi Z-Wave, you will need a Raspberry Pi, USB-C power cable with adapter, Ethernet cable, SD card and SD card reader, Z-wave USB dongle, smart home appliances, and a RPi case.
• Use Balena Etcher to create a bootable SD card and download Home Assistant for Raspberry Pi Z-Wave to connect and monitor the Z-wave devices with Raspberry Pi.
• Assemble the Raspberry Pi properly to ensure optimal performance and stability, and add Raspberry Pi Z-Wave integrations.

However, some software programs are slightly easier to install into a Raspberry Pi than others. That’s likely why you are here reading this right now, right?

If so, you have come to the right place. In this article, we are going to take a look at how you can easily set up the Dakboard platform on your Raspberry Pi so that you can access it even from such a small device! 

What Is Dakboard? 

Dakboard is a digital wall calendar that is designed to sit on a computer’s desktop, and the app has become very beloved amongst computer users thanks to its customizability, and how beautifully it presents its information to users. 

Because of how useful it is, it can be a total asset when added to the desktop of a Raspberry Pi computer, so let’s see how you go about installing it on your computer.

How Do You Set Up Dakboard On Raspberry Pi?

Before you go about adding Dakboard to your Raspberry Pi, you will need to make sure that you actually have a Dakboard account that you can use. This is because Dakboard is a web-based calendar platform, so you will need to ensure that you have an account.

Step 1 – Update Your Raspberry Pi

Once you have a Dakboard account that you can log into, head to your Raspberry Pi, and open the command terminal. Before you go about installing Dakboard to the device, you will need to ensure that your Raspberry Pi OS is up to date.

Head to the command terminal and enter the command:

“sudo apt-get update”

After you have entered that command, follow it up with:

“sudo apt-get upgrade”

Quickly restart your Raspberry Pi, and it will now be running on the latest firmware.

Step 2 – Create A Dakboard Display

In order for a Dakboard calendar to show up on your Raspberry Pi desktop, you will need to make sure to create a display, which is a version of the calendar that will display on various devices. 

Head to the main landing screen of the Dakboard website, and look for the sidebar. You should notice a button that says “Displays & Devices”, click on this button, and you will then be brought to a new menu screen.

Provided you have not yet created a display already, there should be a large green button in the center of the menu screen that should read ‘Add A Display’. Clicking on this button will allow you to start creating a new display.

From here, you will be brought to a menu screen that will allow you to enter the information pertaining to your Raspberry Pi device so that you can safely port over the calendar display. Enter all of the information as requested, and then hit “Save”.

Step 3 – Grab Your Dakboard URL

Now that your Raspberry Pi device is registered with Dakboard, you will then need to get ahold of the URL which will allow the calendar to be displayed on your Raspberry Pi’s desktop.

Head to your registered device on the Dakboard screen, click the three dots, and then click ‘Info’. This will bring up a new menu screen that will display all sorts of information, including the “Display URL”, which you will want to copy down.

Step 4 – Boot Up Dakboard On Raspberry Pi

Now that you have the display URL for the calendar, boot up your Raspberry Pi, and then open up the command terminal.

Of course, you will want your Dakboard calendar to be visible from boot-up every time, so you will need to edit the ‘Autostart’ file to allow this, which can be done by typing:

“sudo nano /etc/xdg/lxsession/LXDE-pi/autostart”

Once this has been done, you will then need to make sure that the Dakboard calendar is able to load up upon booting the system, which will be done via the Chromium web browser. Head to your command terminal and type in:

“/usr/bin/chromium-browser –noerrdialogs –disable-infobars –kiosk –app=<XYZ> &”

Make sure that the “XYZ” in the code above is replaced with the URL that you copied earlier from the Dakboard website. This will allow the Raspberry Pi to access the Dakboard calendar.

Once you have entered this code, simply close down the command terminal.

Step 5 – Reboot Your Raspberry Pi

The final step is one of the most crucial, as rebooting the system will allow all of your changes to be put into action.

Upon restarting your Raspberry Pi, you should now see the Dakboard calendar displayed right away on the desktop screen.

Our comprehensive “how-to” guide puts together everything you need to know to build your own weather station using Raspberry Pi as its core!

What Is Raspberry Pi?

Raspberry Pi is a credit card-sized computer that is designed to be plugged into a TV or a computer monitor and can be used for a number of purposes, including computer programming, games, music, and using IoT devices. 

Before we take a closer look at the nuances of building your weather station, it is worth taking a look at how it will work. There will be three elements:

• Your own Raspberry Pi hooked up to a sensor to measure humidity and temperature, via a General Purpose Input/Output Breadboard Extension (GPIO)
• A Python script – this will read the information collected from your chosen sensor or sensors, and transfer it to an SQLite Database to be stored.
• An SPA – this is a Single Page Application written in PHO. This can read the data from the data that is collected from your database and make it readable. The code in this section will be reduced thanks to the application being based on the Twig template and the Slim Framework.

What Will I Need?

There are a number of prerequisites that you will need to secure, and these include

• A Raspberry Pi running Raspberry Pi OS (previously known as Raspbian). This should be powered by a wall adaptor or a USB cable.
• A DHT11 humidity and temperature sensor – this is usually the cheapest, most accessible option
• Four jumper wires
• A GPIO Breadboard
• 10k Ohm pull-up resistor

Step 1: Connect The DHT11 Sensor To The Raspberry Pi

Once you have gathered all the equipment, it is time to get started.

The first step is to set the DHT11 sensor up with the GPIO Breadboard extension – this will allow the sensor to read properly.

Remove the case from your Raspberry Pi, and connect the T-cobbler to the breadboard.

Join the T-cobbler to the 40-pin cable on one side, and plug the other end of this 40-pin cable into the GPIO pins of the Raspberry Pi.

Next, join your DHT11 sensor into the breadboard, making sure that the top and front face the left side.

Connect the GND of the sensor to a GPIO pin – this will be a white-colored cable – and then join the VCC pin of the sensor to the 3.3v pin – this will be the longer of the green wires.

Join the OUTPUT pin of the sensor to the GPIO 17 pin (the yellow wire), and then join a 10k Ohm pull-up resistor between the VCC and the Output.

Step 2: Set Up The Raspberry Pi

Once your wires are in place, you need to install and configure the software needed for your weather station onto your Raspberry Pi, and there are several packages to include.

You will need to kick things off by running a specific command:

sudo apt-get update
sudo apt-get install -y \
npm \
php8.0-cli \
php8.0-fpm \
php8.0-intl \
php8.0-csalite3 \
python3 pip3 \
nainx \
sqlite3

Following this, ad the pi user to the gpio and www-data groups by running another command:

sudo usermod – uG gpio www-data pi

Change and enable the www-data’s shell by running another command:

sudo usermod – shell/bin/bash www-data

And finally, install Pipeny as follows:

pip3 install – user pipenv

Step 3: Create A Project Directory For The Application

A key element of any Raspberry Pi project is code, and your weather station is no exception to this rule.

Before any code can be written, however, you need to do two things: firstly, create the structure for the project directory, and secondly, change into the top-level directory.

The following code will be required to achieve this:

mkdir – p raspberrypi-weather-station/public/css \
raspberrypi-weather-station/data/ \
raspberrypi-weather-station/ bib \
raspberrypi-weather-station/ templates
cd raspberrypi-weather-station

To summarize, these commands will instruct the creation of a new directory, named raspberry-pi-weather-station, and this will contain four smaller sub-categories:

• bin – will contain the Python script
• data – will contain the SQLite database for the application
• public – will contain the PHO file required to power the PHO app, as well as a directory named css. This will contain the PHO applications CSS file.
• templates – will contain the Twig template required by the PHP application to render output.

Step 4: Create The Database For The SQLite Application

Once the project directory is created, you need to create the SQLite database for the project – this tends to be the preferred option thanks to ease of configuration, as well as lower overheads.

The schema for the database will consist of one table of three columns:

• Humidity stores humidity readings
• Temperature stores temperature readings
• Timestamp stores time and date of each reading, and will be inserted automatically using the current value.

This database is created with the command:

sqlite3 data/weather_station.sqlite

While the schema is created with another command:

create table weather_data
(
temperature real default 0.0 not null,
humidity real default 0.0 not null.
timestamp DATETIME default CURRENT_TIMESTAMP
);

This process will create the applications SQLite database, and you will be ready to proceed to the next step.

Step 5: Create Python Script To Read DHT11 sSensor

Step 5 includes creating a Python script to read the DHT11 sensor and gather data on humidity and temperature – you will need to first install Adafruit_DHT package to allow the script to work, and this can be achieved with the command:

Next, create the Python script by heading to the bin directory, creating a new file names dht11-sensor-reader.py, and then insert the code:

import Adafruit_DHT
import os
import random
import sqlite3
import time
from sqlite3 import Error
def create_connection(path):
    db_conn = None
    try:
        db_conn = sqlite3.connect(path)
        print(“Connection to SQLite DB successful”)
    except Error as e:
        print(f”The error ‘{e}’ occurred”)
    return db_conn
def execute_query(db_conn, query, query_parameters):
    cursor = db_conn.cursor()
    try:
        cursor.execute(query, query_parameters)
        db_conn.commit()
        print(“Query executed successfully”)
    except Error as e:
        print(f”The error ‘{e}’ occurred”)
gpio_pin = 17
database_file = ‘data/database/weather_station.sqlite’
humidity, temperature = Adafruit_DHT.read_retry(database_file, gpio_pin)
if humidity is not None and temperature is not None:
    connection = create_connection(‘./data/database/weather_station.sqlite’)
    add_weather_data = f’INSERT INTO weather_data (temperature, humidity) VALUES (:temperature, :humidity);’
    parameters = {“temperature”: round(temperature, 2), “humidity”: round(humidity, 2)}
    execute_query(connection, add_weather_data, parameters)

 This process imports the packages, and then creates a connection to the SQLite database, as well as running an SQL query against the database.

Next, the variables are defined, the GPIO pin is stored, and this allows the temperature and humidity to be read, the database to be accessed, and the retrieved sensor data to be written to the database.

Step 6: Generate A Crontab Entry To Allow Python Script To Run

Once the Python script has been written, you need to create a Cron job – this allows the script to be run regularly and add the data to the database, and can be achieved with the “crontab-e” command to open the Crontab editor.

You can then choose how often you would like to run the script.

As an alternative at this stage, you can also use a specific editor such as Pico or VIM, and will need to follow the specific requirements for each of these.

Step 7: Build The PHP Web App

The next step is to create a PHP application, and this requires installing everything that the app will need.

You can enter this code into Computer to take care of this:

composer install \
    laminas/laminas-db \
    php-di/php-di \
    slim/psr7 \
    slim/slim \
    slim/twig-view \
    twig/intl-extra

Once this is entered, create a new PHP file in the public directory, and name this index.php. Paste code in this file as follows:

<?php
declare(strict_types=1);
use DI\Container;
use Laminas\Db\Adapter\Adapter;
use Laminas\Db\Sql\Sql;
use Psr\Http\Message\{
    ResponseInterface as Response,
ServerRequestInterface as Request
};
use Slim\Factory\AppFactory;
use Slim\Views\{Twig,TwigMiddleware};
use Twig\Extra\Intl\IntlExtension;
require __DIR__ . ‘/../vendor/autoload.php’;
$container = new Container();
$container->set(‘view’, function(\Psr\Container\ContainerInterface $container) {
    $twig = Twig::create(__DIR__ . ‘/../resources/templates’);
    $twig->addExtension(new IntlExtension());
    return $twig;
});
$container->set(‘weatherData’, function() {
    $dbAdapter = new Adapter([
        ‘driver’ => ‘Pdo_Sqlite’,
        ‘database’ => __DIR__ . ‘/../data/database/weather_station_test_data.sqlite’
    ]);
    $sql = new Sql($dbAdapter, ‘weather_data’);
    $select = $sql
        ->select()
        ->columns([‘temperature’, ‘humidity’, ‘timestamp’]);
    return $dbAdapter->query(
        $sql->buildSqlString($select),
        $dbAdapter::QUERY_MODE_EXECUTE
    );
});
AppFactory::setContainer($container);
$app = AppFactory::create();
$app->add(TwigMiddleware::createFromContainer($app));
$app->map([‘GET’], ‘/’, function (Request $request, Response $response, array $args) {
    return $this->get(‘view’)->render(
        $response,
        ‘index.html.twig’,
        [‘items’ => $this->get(‘weatherData’)]
    );
});
$app->run();

This will import the required classes, initialize the Dependency Injection Container, and register the services “view” and “weatherData”, which retrieve templates for formatting and connecting to the SQLite Database respectively.

This allows a SQL query to be generated to select records from the table you created earlier, runs the query, and stores the results. 

Step 8: Create The View Template

Next, create a view template to allow data to be presented professionally – this is created in the resources/templates directory, in a fresh file titled index.html.twig, to which this code is added:

<!doctype html>
<html lang=”en”>
<head>
    <meta charset=”UTF-8″>
    <meta name=”viewport” content=”width=device-width, initial-scale=1.0″>
    <link href=”/css/styles.css” rel=”stylesheet”>
    <title>DIY Weather Station</title>
</head>
<body>
<h1 class=”mb-4″>DIY Weather Station</h1>
<div>
    <table>
        <thead>
        <tr>
            <th>Date</th>
            <th>Time</th>
            <th>Temperature (&deg;C)</th>
            <th>Humidity (%)</th>
        </tr>
        </thead>
        <tbody>
            {% for item in items %}
            <tr>
                <td>{{ item.date|format_date() }}</td>
                <td>{{ item.time|format_time(pattern=’hh:mm’) }}</td>
                <td>{{ item.temperature|format_number({rounding_mode: ‘floor’, fraction_digit: 2}, locale=’de’) }}</td>
                <td>{{ item.humidity|format_number({rounding_mode: ‘floor’, fraction_digit: 2}, locale=’de’) }}</td>
            </tr>
            {% endfor %}
        </tbody>
    </table>
</div>
</body>
</html>

This imports stylesheets and essentially helps your data to appear in a clear, accessible manner.

Step 9: Generate A Virtual Host

You are now almost ready to start enjoying your weather station – but you first need to ensure that a virtual host is added to NGINX.

Add a new file to /etc/nginx/sites-available, and name this weather_station, before adding the code:

server {
    listen 80 default_server;
    root /home/pi/raspberrypi-weather-station/public;
    index index.php;
    access_log /var/log/nginx/access.log;
    error_log /var/log/nginx/error.log;
    location / {
        try_files $uri $uri/ /index.php;
    }
    location ~ \.php$ {
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:<<X>>.sock;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }
}

The configuration we have included above specifies the location of the web server’s document root (the place where the web server looks for files), which is /var/www/web server/public.

It then asks the system look for an index.html file there. The final step is to enable the correct configuration using this command:

sudo rm /etc/nginx/sites-enabled/default
sudo ln -s /etc/nginx/sites-enabled/weather_station /etc/nginx/sites-enabled/default
sudo systemctl restart nginx

Step 10: Test Out Your Station

Once the process is complete, and if all has gone to plan, you will have a working weather station!

To test, head to http://<<Raspberry Pi iP Address>> to your browser (use the IP address attached to your Raspberry Pi instead of the placeholder), and check out the results!

In today’s post, we’re going to show you how to install Home Assistant on Raspberry Pi. Let’s go!

What Do You Need To Install Home Assistant On Raspberry Pi?

Before we can get into the step-by-step process you need to follow to install Home Assistant on Raspberry Pi, you first need to know what you need to get it done.

Luckily for us, we don’t actually need that much. Below, you’ll find a list of the things you need to successfully install Home Assistant:

• Raspberry Pi
• Power Supply
• WiFi or Ethernet Cable
• Micro SD Card

The things above are what we recommend you need to successfully install the software.

As far as optional things go, a Raspberry Pi case is also helpful, but don’t worry if you don’t have one.

First Step – Download Home Assistant

Once you have everything you need to install Home Assistant, you can start the process of doing so.

The first step in the process is to download Home Assistant. You must download the version of Home Assistant that suits your Raspberry Pi.

At the time of writing, Home Assistant recommends that we use Raspberry Pi 3 or 4 (however, the Compute Module 4 may also be a great option).

To download the software, head over to the Home Assistant GitHub.

When you open GitHub, you’ll be greeted by a long list of available downloads.

You should now look for the version of Raspberry Pi you use and click on it. This will start the download. The file name will end in .img.gz.

Second Step – Installing The Home Assistant Software Onto Your SD Card

When your download has finished, you can start to write it onto your SD card. Follow the steps below to do this correctly.

To make this step easier, we will be using a software called Etcher.

Available for download on Balena.io, this is a simple-to-use software that works on macOS and Windows.

Once downloaded, open Etcher and select the Home Assistant image. To do this, click on the “Select Image” icon and search for Home Assistant.

Next, select your SD card. Do this by pressing the “Select Target” icon and selecting the right SD card.

If there’s only one writable drive, the software will select it for you. When you find the right drive, press the “Flash” icon.

Those that want to set up their Raspberry Pi to use WiFi should hold off on inserting their SD card. Instead, follow the instructions in the next section.

If you plan on using your ethernet cable for an internet connection, skip the first boot section.

Third Step – Setting Up WiFi For Your Home Assistant

In this section, we will show you how Home Assistant can be connected to a WiFi connection.

At this point, you’ll want to plug the SD card into your computer.

1. On the file that says “hassos-boot”, create a folder and call it “CONFIG”. The Home Assistant software will automatically read that folder for any configuration alterations.
2. Within that folder, create another folder with the name “network”.
3. Now, within the “network” folder, you need to create a file with the name “my-network”.
4. Inside your “my-network” file, you can now start to insert the configuration that helps define your WiFi network for the Home Assistant software. To do this, we have to replace three things.

The first thing you need to replace is “”. Do this by using an online generator to produce a new one. UUID Generator can do this for you.

Next, you need to change “”. You need to change this to your network’s SSID.

Finally, replace “” with your WiFi network’s password. Once that’s done, we are ready to boot up the Raspberry Pi (see also ‘How To Fast Boot Raspberry Pi‘).

Fourth Step – Booting Up Home Assistant On Raspberry Pi

You can now start to open the Home Assistant Software. For this, you will have to visit one of three web addresses.

Most users will find that they can access the Home Assistant homepage using http://homeassistant.local:8123.

If that doesn’t work, you could try http://homeassistant:8123.

Finally, if neither of those work, try http://[IPADDRESS]:8123. For this final option, you will need to know the IP Address of your Raspberry Pi.

Be patient with the initial loading of the software as it can take a while. Occasionally, you might be greeted with “Site Can’t Be Reached”.

If this happens, wait for approximately 20 minutes. When Home Assistant has booted up, you might be asked to refresh your browser.

After that, you’ll be prompted to make an account for the software. To do this, enter your details and then select “Create Account”.

In the next section, you will be told to name your “home”. You should also be asked for your location.

Make sure you get this right as the location will help the software manage your automations. If you click on “Detect” the software will do this for you.

After that, you’ll have to select the unit system you use. “Metric” is selected by default. You can then click “Next”.

Once you’ve filled out the required details, the software will show you a list of the devices it has already picked up.

You can set up the detected devices there and then by clicking + above the device. Alternatively, you can finish the first boot-up by pressing “Finish”.

The initial setup of Home Assistant on a Raspberry Pi is now done. You will now be able to see the main Home Assistant dashboard.

Fifth Step – Adding Integrations

After your initial setup, you can add more integrations (such as Z-wave etc.).

This doesn’t take long and is relatively straightforward when you know what to do. We’ll show you how to do this now.

To add new integrations, click on the “Configuration” icon found on the sidebar.

After that, scroll down until you find the “Integrations” tab. For most users, this is found near the top.

When you click on the tab, you’ll be taken to a screen that shows you all the devices the Home Assistant software has picked up.

If you can’t see the device you want, you can easily add them yourself by selecting the + icon found at the bottom of the screen.

This will open a search menu. Use that search menu to find other available integrations.

All Done!

Now you’ve followed the steps we’ve outlined, your Home Assistant download should be running smoothly and successfully with your Raspberry Pi.

You can now start to enjoy the perks and benefits that come along with the software, and set up home automation.

In Conclusion

At first glance, the process of installing Home Assistant on Raspberry Pi might seem like a minefield, with lots of technical, nitty-gritty details to remember.

However, once you get started, you quickly come to realize that installing Home Assistant on your Raspberry Pi is actually a relatively effortless process.

As long as you follow our steps carefully, you should have no problem setting up Home Assistant on your Raspberry Pi.

We’ve laid everything out for you clearly and in detail. All you have to do now is execute each step.

Considered the best-selling computer in Britain, the single-board technology was created for the purpose of teaching basic computer science, with the computer now being used for robotics and other creations. 

Among these inventions, it has become popular to use Raspberry Pi to produce weather monitors, with the low cost and open design making the computer easy to use.

Because of this, it is also possible to construct your own daylight sensor, which can measure sunlight and be used to activate other devices such as clocks. 

So if you are interested in making your own daylight sensor, then you have come to the right place. In the following guide, we are going to teach you how to make a daylight sensor, while also outlining the equipment you will need and the simple Python script that can be used to activate the finished device… 

What You Will Need 

Before you can start constructing your daylight sensor, you will need the following equipment that we have listed below. 

While it is possible to complete this task without breadboard gear, we would recommend purchasing some for the amount of circuitry work the sensor requires. 

Recommended 

• Raspberry Pi 
• Power source 
• Micro SD card 
• Ethernet cable or Wi-Fi 
• LDR sensor (light)
• 1uF capacitor 

Option Equipment 

• Raspberry Pi case 
• USB keyboard 
• USB mouse 
• GPIO breakout kit 
• Breadboard 
• Breadboard wire 

How To Make A Daylight Sensor 

If you are interested in computer circuitry, then this light sensor is a great way to hone your skills, as it requires a simple circuit that will teach you the ins and outs of the creative process. 

Light Dependent Resistor (LDR) 

The light-dependent resistor (otherwise known as the LDR) is the most important component of the daylight sensor, as the device is capable of detecting whether its surroundings are in the day or night. 

When it detects light, the daylight sensor will have a resistance of only a few hundred ohms, while in the dark, the daylight sensor will be able to generate resistance of several megohms. 

Capacitor 

The capacitor (see also ‘What Is Capacitance?‘) is included in the final circuit to help measure the resistance of the LDR, with the device working similarly to a battery, storing energy for electrical surge. 

Like a battery, the capacitor will charge (see also ‘How To Charge A Capacitor Without A Resistor‘) when receiving power and will discharge when no longer connected to the power source.

By using this in conjunction with the LDR, we are able to determine how much resistance the LDR is producing, which also helps tell it whether it is day or night. 

How To Make The Sensor Circuit 

To make sure that the daylight sensor works correctly, you will need to assemble an efficient circuit. This can be done by following the steps below, where we have outlined the process to help you. 

However, it is important to note that we are referring to the physical numbers of the pins in their logical order: 

1. To start, you will need to connect pin #1 (3V3) to the positive rail located on the main breadboard. 

2. Once you have done this, take pin #6 and connect it to the ground rail located on the main breadboard. 

3. Next, place the LDR sensor onto the breadboard and connect a wire from one end to the positive rail. 

4. On the other side of the LDR sensor, place a wire and connect it to the Raspberry Pi by holding it in place with pin #7. 

5. To complete the circuit, connect the capacitor from the wire to the negative rail on the breadboard, while making sure that the negative pin has been connected to the negative rail. 

Now that you have assembled the circuit, it’s time to take a look at the Python code that will control the sensor. 

However, if you are still having trouble assembling the circuit, then you can find informative diagrams on the web. 

How To Code The Daylight Sensor 

Fortunately, the code needed for the sensor is pretty simple and will tell us whether it is day, afternoon, or night. 

The only setback is that Raspberry Pi does not feature analog pins, which means you will never be able to accurately measure the resistance of the input.

Because of this, we advise measuring the time it takes for the capacitor to charge as this method is an accurate way to tell whether it is light or dark. 

If you are still new to Python, we recommend that you take a crash course on the basics of the program, as this will give you a better understanding of how the coding process works. 

1. To start, you will need to import the GPIO package that you will need to communicate with the GPIO pins. It is also advisable to import the time package, as this will allow you to put the script to sleep if needed. 

2. Once you have done this, set the GPIO mode to GPIO.BOARD, which will allow you to refer to the pins through the numbering in the code. Because the circuit only has one input/output pin, you will only need to set up one variable. 

3. For the next step, you will need to use a function called rc_time, which requires one parameter. This parameter is the pin in the circuit, which can be initialized through a variable called count. 

4. When the pin goes high, set it as the output and put it on low before letting the script sleep for around 10 minutes. 

5. When the time is up, set the pin as the input and enter a while loop until the pin goes high. This is when the capacitor reaches a charge of 3/4.

6. Once the pin goes high, return the count value to the main function. It is possible to use this value to turn on an LED, activate another device or record the statistics on any variance in light. 

How To Run Code On Raspberry Pi 

The final step in the process is extremely easy, even though we still think it’s important to learn the ins and outs. 

To download the code to your Raspberry Pi, you can use a git clone, which can be activated by a simple keyboard command. However, it is also possible to copy and paste the code into the program, although you have to make sure that it is a Python script (see also ‘How To Install Python Libraries‘). 

Once you have done this, you can save and exit the file by pressing CTRL + X then Y. Then you can run the code by using the following command: 

• Sudo python light_sensor. py

This should run the script smoothly through the computer, allowing you to activate your very own daylight sensor. 

Final Thoughts 

While constructing your own daylight sensor can be difficult, it is also necessary to learn more about circuitry and computing. 

With the right attitude, you will be able to create your own daylight sensor in no time, while also gaining experience with circuits and the coding process.
