You need:

 

Step 1: You Raspberry Pi prepare

Now that you've got everything ready, let's start installing Raspbian Lite. Raspbian Lite is the lightest version of Raspbian, the OS for the Raspberry Pi. Insert your micro SD card into your computer via an adapter and start the Raspberry Pi imager on. stand the Raspberry Pi imager to make adjustments to your system.

What you will see now is the following:

Here you can see the Raspberry Pi imager. Click on the left button. It is labeled "CHOOSE OS".

We will first select an Operating System (OS). In this case, Raspbian Lite.

Here you see the OS selection menu. Click on Raspbian (other).
Here you can choose between Raspbian Lite and Raspbian Full. We choose Lite.

Now that you have selected your OS, it is time to select the correct SD card.

Here you can see that your OS is selected. Now click on "CHOOSE SD CARD".

We use a 16GB micro SD card. What you see here may differ based on your micro SD card.

Here you see a list of all SD cards. Select your SD card here.

If you have selected your micro SD card you will arrive at the next screen.

Now that you have selected your SD card. Are we going to write the OS on this card. Click on "WRITE".

You will now go through the next three screens. When the writing process is finished, you can close the imager. Then remove the micro SD card.

Here you can see a progress bar with the progress of the imager writing the OS
Here you will see a progress bar showing how far the imager is with verifying the written OS
When you see this screen, the whole process is done. Shut down the imager and remove the micro SD card from your PC.

Step 2: De Raspberry Pi Set up

Now that you have Raspbian Lite installed on your micro SD card, it is time to make some adjustments to the settings. Be the first to insert the micro SD card back into the computer. This process consists of a step that you only need to perform if you do not have an Ethernet connection. The second step is necessary for both an Ethernet connection and a wireless connection.

Step 2.1: Configure WiFi (not necessary if you have an ethernet connection)

First go to the windows explorer and then to this computer.
You will now find a similar screen to the photo on the right. Now click on the “boot” disk.

You are now in the windows explorer. Click on My Computer. Then select the "boot" drive.

We are going to work in the “boot” disk. In this you will find something similar to the following photo.

Here you see an overview of the "boot" disk.

What we are going to do now is edit the ”wpa_supplicant.conf” 'and add it to the ”boot” disk. You should have downloaded this file from supplies. If not, look below this text. Open the document with notepad. You should now see the following text. If not, copy the following text.

wpa_supplicant.conf

 

ctrl_interface = DIR = / var / run / wpa_suppliant GROUP = netdev
update_config = 1
country = NL

network = {
 ssid = "Your_Network_Name"
 psk = "Your_Network_Password"
 key_mgmt = WPA-PSK
}

Now change “Your_Network_Name” and “Your_Network_Password” with your WiFi's name and password.

In our case:
Name: Electronics For You
Password: Electronics @ 123

Here you see an example of the end result.

ctrl_interface = DIR = / var / run / wpa_suppliant GROUP = netdev
update_config = 1
country = NL

network = {
 ssid = "Electronics For You"
 psk = ”Electronics @ 1234 ″
 key_mgmt = WPA-PSK
}

If you do not want your WiFi password to be readable in the configuration file, use the following to encrypt the key.

wpa_passphrase “Your_Network_Name”

Then enter your WiFi password and you will receive an encrypted key in response.

Change the above configuration:

FROM

 psk = "Your_Network_Password"

to

psk=17235aaa79fff0-932781590872387954237548127
(note: WITHOUT quotes)

 

If you have edited this document and saved it to the "boot" disk you can go to the next step.

Step 2.2: Configure remote approach

Go to the windows explorer and then to this computer. Now click on the hard drive named: ”boot”. And paste the following file here: ssh       

You are now ready to install domoticz. Remove the micro SD card from your PC and put the micro SD card in your Raspberry Pi. Now connect the Raspberry Pi with your power supply and possibly with an Ethernet cable.

Step 3: Install Domoticz

We are now going to connect to our Raspberry pi. This process consists of two steps. Finding the IP address of the Raspberry and connecting and installing domoticz.

If you have a keyboard and screen connected, you can also log into the terminal and run the following command.

ip ace

This allows you to see both the WiFi and wired IP numbers.

Step 3.1: Find the IP address

Search in the search bar “cmd”. Then click enter.

The program shown on the right should now be open. Type the command 'ipconfig' and hit enter.

 

Here you see the program: Command Prompt.

Then you will see something similar to the photo on the right.

Search for IPv4 Address. Here you will find your IP address. This is important for finding the IP address of your Raspberry Pi.

 

Your IP address will consist of xxxx, in our case 10.120.0.166. 

Open now advanced IP scanner, a preparation program.

Here you see the results of ipconfig. Find your IPv4 Address and write it down.

You will see this now. In the circled line type xxx0-254, so in our case 10.120.0.0-254.

Then click Scan.

This is the home screen of advanced IP scanner

Wait until you have finished scanning.

Here advanced IP scanner is scanning.

You will now see a list of Device names, IP addresses, Manufacturers and MAC addresses. At the Raspberry Pi unfortunately we can't see a manufacturer or name. So we're going to search by MAC address. A MAC address consists of XX:XX:XX:XX:XX:XX. At a Raspberry Pi it always starts with DC:A6:32: or B8:27:EB: . Now look for such a MAC address and see which IP address it contains. In our case '10.120.0.154'.

The IP scanner is ready. Now we are going to find the Raspberry

Step 3.2: Connecting with you Raspberry Pi

Go back to the windows search bar and type 'cmd'. Click on enter.

You will now see the following screen.

 

Now type 'ssh pi@xxxx', where xxxx is the IP address of your Raspberry Pi is. So in our case it becomes 'ssh pi@10.120.0.154'. After filling in, click on enter.

Command Prompt

You will now see the following. Type 'yes'. Click on enter.

SSH authentication

You will be asked for a password. The default password is 'raspberry'. Enter this password. While typing passwords, no characters will appear. This is normal. Click enter after entering your password.

 

 

Here you enter the password of the Raspberry Pi .

You are now logged in to your Raspberry Pi. The first thing we are going to do is create a new password so that not everyone can access your Raspberry Pi can. Type 'passwd' and hit enter. Type your current password and twice the new password. Click enter after each password.

Change your password here Raspberry Pi

You now have a secure, accessible only to you Raspberry Pi. We still need to perform a few more steps until the domoticz is ready for use. Type the command 'sudo apt-get update' and hit enter. Wait for the process to finish. This command updates you Raspberry Pi.

You updated your Raspberry Pi

Now that we have prepared everything, the time has finally come. We are going to install domoticz. Type the command 'sudo su'. Then type
'curl -sSL install.domoticz.com | sudo bash". Click on enter.

This command installs Pi-hole

If you want to reconfigure the ports, you can run the above command again.
You will then be given the option to reconfigure.

You can also indicate here whether you only want http access via port 8080, or https over port 443

A number of configurable settings will then appear. We recommend the default settings, but if you have already installed OpenMediaVault change port 8080 to 8888. You can navigate through the steps with enter.

raspberry 5

The current version of the Raspberry OS Bookworm has not had support for the library libssl1.1 for a while.
A well-known workaround was to disable SSL in the config.

DAEMON_ARGS=”$DAEMON_ARGS -sslwww 0″

Since some people still experienced problems, we have a working installation manual for you below.

We put Raspberry OS (bookworm) on the SD card (full) with the imager and placed it in an RPi5.

After the automatic update of the OS, we executed the command below.

sudo bash -c “$(curl -sSfL https://install.domoticz.com)” 

​ We turned on http on 8080 and https (ssl) on 443

After a reboot, domoticz was available over both http and https
(of course a warning because the certificate is not valid from the SSL, but this is normal behavior.)

In our case, the good SSL library was immediately installed properly on the OS
(This is a new package included in the OS last month?)

There was also no problem with automatic starting.

Below is some additional debugging information that may help you with an existing installation.

root@raspberrypi:~# lsb_release -a
No LSB Modules ARE Available.
Distributor ID: Debian
Description: Debian GNU/Linux 12 (bookworm)
Release: 12
Code name: bookworm

root@raspberrypi:~# ldd /home/pi/domoticz/domoticz | grep libssl
libssl.so.1.1 => /lib/aarch64-linux-gnu/libssl.so.1.1 (0x00007fff5d250000) <——— this was the problematic library that was not included by default with RPi OS.
root@raspberrypi:~# ss -tulips | grep domo

​if you don't have this library:
apt-get update
apt-get install libssl1.1

Manually downloadable here:
(https://archive.raspberrypi.com/debian/pool/main/o/openssl/libssl1.1_1.1.1w-0~deb11u1+rpt1_arm64.deb)

The error message if this library is missing looks like this:
sudo journalctl -u domoticz
Nov 12 21:38:49 RaspPi systemd[1]: Starting domoticz.service – LSB: Home Automation System…
Nov 12 21:38:49 RaspPi domoticz.sh[9933]: Time synchronized, starting Domoticz…

Step 4: The web interface

To connect to the web interface, go to your ip address in your web browser Raspberry Pi, xxx.xxx.xxx.xxx, and then type “:” and the port you chose. If all goes well, 8080 or 8888. In our case we go to http://10.120.0.154:8080 or http://10.120.0.154:8888 (https://10.120.0.154)
