Zigbee Temp & Humidity Sensor rapid battery drain when connected to home assistant

Configuration Zigbee
1

I’m experiencing CR2032 batteries die within a 12 hour period once I connect the Temp & Humidity Sensors to Home assistant. Can anyone offer any advice on how I can troubleshoot to work out what could be causing the rapid drain.

Bit of supporting info if required:

  • Zigbee Temp & Humidity Sensor ZTH05
  • HomeAssistant running on VM on Synology NAS 423+
  • Zigbee coordinator is Home Assistant Connect ZBT-1 (via official extender into NAS)
  • Distance from coordinator to sensor is 2 meters with line of sight.
  • Connected with ZHA

I’ve tried checking the logbook to see if there’s some logs which might show something continually activating but in logbook I only see one event when filtering on the device which just says when it became unavailable. Tried a brand new battery and it drained it flat within 12 hours and when not connected to Homeassistant they were fine for a week before I got home assistant up and running. Are there any more detailed logs or common issues of where to begin investigating the issue?

For info in case others are interested… I’ve installed Z2M and started using this istead of ZHA. So far so good, the sensor is still alive with good battery after a day (it would have been dead long before this with ZHA) so presumably it was an issue with ZHA. Still would be interested to understand if there should be any logging available to see what was causing the drain with it being connected via ZHA
