I just manage to add this door/window sensor to Homey, but the contact alarm is constantly ON. It’s not triggering, it’s just permanently ON all the time.
I had the same issues with TRÅDFRI motion sensor. The sensor triggered ON and was just ON permanently.
Looking through the forums it feels I’m the only one with these issues or the only one using the IKEA stuff?
I haven’t got one myself but it sounds like a similar issue to the zigbee door/window sensor and the Vallhorn zigbee motion sensor that homey users had issues with. Most users were using alkaline/1.5 volt battery. Not sure whether you are also but if you are try using the rechargable 1.2 volt battery. If it’s the same issue as their previous sensors then I suspect having higher volts is causing the issue of it being stuck and not timing out the detection.
I’ve ordered a few of these so I can do a quick test once they arrive. Otherwise you might need to check whether there is a newer firmware update that has addressed any issues
