Zigbee binding RWL021 philips hue dimmer switch disonnect frequently

  • Platform information: Openhabian with RP3B

I have a Philips Hue Dimmer Switch RWL021 with a Nortek Security & Control HUSBZB-1 Usb Stick. The Hue Switch becomes offline after 12 hours approximately. The only way to make it operational again is to put it in a setup mode and do the pairing again. Does anyone have the same problem?

I also have hue sensors , an ikea outlet plug, and some ikea bulbs. The other zigbee devices never go offline.

I borrowed a xiaomi sensor from a friend and I notice that the same problem occurs also with xiaomi sensors but I read at the forum that the xiaomi sensors are not very compatible with zigbee

I am new to openhab and I might be looking it from the wrong angle but I have noticed that

  1. the zigbee devices that are plugged into an outlet do not have the same problem
  2. the battery devices that exchange frequently info with the coordinator do not have the same problem
  3. The problem occurs only with devices that remain idle for longer period of time (devices with smaller batteries)

is the problem the longer idle times or is ti something else

Thanks
