YW!
More options:
restart Homey in recovery mode and choose “full software download” from the menu when presented;
Here’s a howto.
This has solved the weirdest zigbee issues, but no guarantees here.
Note: it only installs the firmware from scratch, it shouldn’t touch anything of your work.
But, as always, do keep a recent backup at hand
In case that doesn’t help, you can reset Homey zigbee as a last resort.
This will remove all paired zigbee devices, and you’ll have add your zigbee devices and fix the flows involved.
Fixing those flows can be a nightmare, luckily we can use this very neat script bij Martijn Poppen.
Unfortunately I can’t tell you if Homey is dying, BUT the original power brick is known to degrade over time, causing zigbee malfunctions for instance; make sure to replace it by a decent one from a well known brand, 5VDC - 2A minimum. I’d replace the USB cable as well.
