Zigbee problems since 100.3 upgrade

Hi,

Since upgrading to 0.100.3 today, my zigbee performance has gone down the drain. I am using ZHA with a conbee 2 stick. It has been running fine previously. I have not made any changes to my zigbee network today. It will work for a bit after a restart, but then it stops working some time later.

Looking through the homeassistant log I have found these entries:

2019-10-23 17:51:16 WARNING (MainThread) [zigpy_deconz.api] No response to 'Command.write_parameter' command
2019-10-23 17:51:16 ERROR (MainThread) [homeassistant.core] Error doing job: Task exception was never retrieved
Traceback (most recent call last):

concurrent.futures._base.TimeoutError

But I have no idea where to go from here debugging this. Any help of suggestions would be appreciated.

Cheers.

Time to eat humble pie.

Turns out I had left zigbee2mqtt stopped, but with start on boot still enabled. So I think the process of updating hass triggered a reboot (as opposed to just a restart). And I’m guessing it was grabbing the conbee before ZHA could.

Disabling (and removing it this time) has fixed the problem.
