It might be solved one day, but…
For now, I’d move Ikea lights to the Ikea hub first. I had no issues with the Trafri outlet + Aqara sensors. Only with Ikea lights.
Idk if you run out of zigbee routers for Homey in this case?
Oh, Aqara contact sensors don’t tend to look for other / better routes, so when they were paired before you added Ikea lights, you’re probably safe.
