I have a issue since a few minutes: I can‘t control my Zigbee devices anymore, I mean the devices connected directly to Homey (e.g. Hue Zigbee). Tried to take a look to the Zigbee settings which tells me that an error occurred. Tried to take a look to developers site, no devices.
I already tried to restart Homey, no success.
I am using V2.0.
You could try to PTP (Pull The Plug) and leave it unplugged for >13 minutes. After that, wait for at least half an hour to see if the devices re-appear. If that doesn’t help I’d file a ticket at https://support.athom.com/hc/nl/requests/new
Also having issues on my ‘daily use’ Homey and adding zigbee devices.
I get a time-out adding (xiaomi) zigbee devices. After several reboots i had success adding one device.
Having 12 mains-powered zigbee devices, so the max limit of battery powered could not be the issue.
