FHEM (stands for "Fast Home Easy Monitoring") is an open-source home automation software, which allows users to set up various smart devices in their homes to control temperature, lighting, and other functionalities. In this tutorial, we will guide you through the process of installing FHEM on NixOS latest.
Before we begin the installation process, ensure that your NixOS latest system is up to date.
The first step involves adding FHEM to Nixpkgs repository as follows:
$ sudo nano /etc/nixos/configuration.nix
Under systemPackages, add the following line:
{
[...]
environment.systemPackages = with pkgs; [
[...]
fhem
];
}
Save and exit the configuration file using Ctrl + X, then Y, followed by Enter.
FHEM runs an HTTP server that provides a web interface for controlling smart devices. To enable the FHEM HTTP server, add the following line to your NixOS configuration file:
{
[...]
services.fhem = {
enable = true;
};
}
Save and exit the configuration file using Ctrl + X, then Y, followed by Enter.
Reload the NixOS configuration by running the following command:
$ sudo nixos-rebuild switch
After the rebuild process is complete, start the FHEM service by executing the following command:
$ sudo systemctl start fhem
Check the status of the FHEM service to ensure that it is running correctly:
$ sudo systemctl status fhem
The FHEM web interface is accessed via a web browser. The default URL is http://<hostname or IP address of your NixOS system>:8083/fhem. You should see the FHEM dashboard, which displays the connected devices, logs, and other information.
In this tutorial, you learned how to install FHEM on NixOS latest. You can now use FHEM to monitor and control various smart devices in your home via the web interface.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
