homebridge-hue: Xiaomi Aqara wall switch not shown as switch/timeouts

I got added a light to PHOSCON app via conbee stick. It was working for hours.

But now I got the following error after a period:

[2018-12-10 16:47:05] [ConbeeStick] ConbeeStick: gateway error 3: resource, /lights/3, not available
[2018-12-10 16:47:05] [ConbeeStick] Schlafzimmer Fluter: homekit on changed from 0 to 1

Hardware switch and PHOSCON app are still working, only homebridge shows this error.

And the switch is not shown as real switch like the original hue one, only as unknown device. Will there we an update in future?
