Hobby project for making my aprtment smart-controlled.
For now it can only control lights, but will be continued.
The ceiling lights are Trådfri from Ikea. The chain light is a christmas decoration, which is set up all year. The desk lamp is a simple desk lamp. The Ikea Trådfri is controlled by transistors emulating button presses on the remote. The desk and chain light are controlled with two relays.
