All ZigBee disconnected - recovery

[cag014 731]

I see that many users have a problem with ZigBee, frequently all devices showed disconnected and don't work anymore.

If "standard" actions (like disconnecting/reconnecting power, reloading latest backup) don't help, here some steps that could help to recover and no need to reinclude all devices again.

1. Reset Zigbee Network 

Please login or register to see this spoiler.

 

2. Include any ZIgBee device that in use in your system to initiate ZigBee network. Wait about 2 minutes and verify that included ZigBee device is working properly.

Don't worry it will work later with the original ID, no need to change any code

 

3. reboot the system with your latest working backup

 

4.  At the beginning you might see that all ZigBee devices are still disconnecting.  Please wait several minutes till the system will stabilize ZigBee communication (could take up to 10 minutes)

 

Now all ZigBee devices should work properly as before.

 

This procedure helped me to recover at least 7 times.

 

In some cases, just one (or more, but not all of them) ZigBee device become unstable, meaning takes time to turn ON/OFF and frequently shown as disconnected.

I suggest solving the problem as following:

1. Create a backup

2. Reinclude the device

3. Reload saved backup

 

The device should work using his original ID. No need to change scenes or code.

 

Hope it helps

In theory, 5.172 beta (5.180) has a mechanism which automatically restore the configuration in case of failure of Zigbee network configuration.
Its possible that even with it, devices will be "disconnected" for some time before restoring the connection - we will check it out.

Thanks for confirming that, @m.roszak. I was wondering if the delay in reconnection after a ZigBee network issue was expected behavior. Good to know the newer beta has some recovery mechanism built in, looking forward to seeing how it performs in real situations.
