Not working zigbee actor

Hello,
I have an actor, that seem to be connected (seen in the map of the zigbee network) that doesn‘t work. The actor is 3m from the repeater. I tried to replace the actor by a smart plug with the same result. I changed the WiFi channel to 1 and the zigbee channel to 15. without change.
Any help is appreciated.

Please clarify what you mean by “actor” and “doesn’t work”… it might also be helpful to know which Zigbee integration and which coordinator device you are using.

Also, FWIW, WiFi channel 1 and Zigbee channel 15 still overlaps. If you want the best separation with no overlap, change to Zigbee channel 25. Fair warning - Zigbee channel 25 has been reported to not play well with older Zigbee devices (2.0-, especially older Aqara).

Thanks, I will give it a try.
