This custom component has been made into an official Home Assistant Integration

Integrate KMtronic devices into Home Assistant. KMtronic offers a large range of IP connected relays that can be controlled over your local area network. This integration maps each of the relays as a separate device, enabling you to control various areas of your home (e.g. using each relay to control different garden sprinkler areas, or controlling electrical distribution of your house from a central board).

To add a KMtronice device to your installation, make sure they are connected to your home network first with a fixed IP. Next, go to Configuration >> Integrations in the UI. Click the button with + sign on the integrations page and from the list of integrations, select KMtronic and insert the IP address, Username and Password of your KMtronic device. The integration will detect how many relays your device has, and will create a switch entity for each of the relays.
