Minor update released today.
Fixes:
batteryVoltage was being parsed by the zigbee.getEvent() and written to the device event log without any textual description. This release makes batteryVoltage an attribute, creates an event with a text description and unit of measurement.
Additions:
Automatic, timed disabling of debug and trace logging after 30 minutes to keep hub logs from filling up. This was suggested previously by @csteele.
