W
h
en
the thermostat is
paired and powered using
external

power
,
it will send a
low battery warning
to the control panel and to the backend/mobile app

that cannot be
cleared.

To remedy this problem, you must
first power and pair the thermostat with battery power only,
then unpair, and finally re
-
pair the device using AC

power. This will prevent the thermostat
from sending low battery notification.

If you are using battery
power

only, there is no issue with this firmware version.

Please note: You cannot power the device with both external and batteries. This
condition will
result in a warning to remove the batteries.
