Hello Rodret
/Ikea were selling off remote control devices for two pounds each when we went there recently. I bought four. Last of the big spenders.
The devices use the old Zigbee connection rather than the newer technology. I’ve paired one with my TRADFRI Ikea gateway and I can control the brightness of a light with it, which is a start. There are a few projects online involving Home Assistant which I’m going to have a play with.
