I regularly (at least weekly) notice that all my zigbee devices have not updated/reported status for several hours, and when I then check zigbee status on developer tools Homey Developer Tools I get the error message “Zigbee Unavailable”. Usually the problem goes away after several hours (8+), sometimes it helps to restart the Homey Bridge but not always.
Is this a common problem or could it be a problem with my Homey device?
Are there any way to get a notification, eg. with a system setting or a Flow sending a push notification, when zigbee is unavailable or a device is not updated for at least X hours ?
I think you’d report it to homey.app/support as well.
Only for Homey Pro models, with a script, or with timers.
(I’m a bit lost on why there’s still no onboard checking mechanism like other zigbee controllers have).
Here’s a very extended guide on how to solve zigbee issues.
Important need-to-know: wifi 2.4GHz and zigbee share the same frequency band.
It’s important to select the least interfering channel numbers
