Iris motion sensors v2 stopped working. Errors in logs

Configuration Zigbee
1

I have several Iris motion sensors (Zigbee) that have been working fantastically until last night when all of them stopped reporting any motion or temperature changes.

I have several other Zigbee devices (hue bulbs, door/window sensors) that have all continued to work without issue.

I’m running Hass.io with Home Assistant version 0.96.5. I just updated today after the issue started, and have tried rebooting as well with no luck.

In the logs I see this error over and over.

2019-07-28 22:56:15 ERROR (MainThread) [homeassistant.core] Error doing job: Task exception was never retrieved

I’m still getting this error every 2 minutes. I tried unpairing and repairing the motion sensors, and they are working sometimes now, but the light bulbs are also somewhat intermittent.

I’m not able to determine what this error message is complaining about, but it keeps spamming the logs ever 2 minutes:
