Besides reporting to Athom Support | Homey, you can consider the following
- When Homey’s firmware was updated just before zigbee broke down, ánd you have a USB backup with the previous firmware, restore that backup.
If that doesn’t help: - Performing a full firmware download, connect Homey with USB cable to a pc/laptop for that.
If that doesn’t help: - Performing a zigbee reset.
First fix your 2.4GHz wifi channel to preferably 1, 6 or 11.
Wifi & zigbee can interfere!
The reset procedure tries to set the zigbee channel to a quiet channel → this is futile when the 2.4GHz wifi channel is on ‘auto’.
Note: This will break the flows involved, while you need to start from scratch pairing your zigbee devices.
There’s a cool script to repair your flows, but you’ll need to copy the exact zigbee device names on beforehand, and name the ‘new’ paired devices slightly different, in case you want to use the script based on device name.
Otherwise you’ll need to lookup the device ID’s on beforehand.
