Is there any low battery alarm
Yes, the sensor has a low battery alarm set at 3V
which is 10% left, when battery output voltage is
lower than 3V, the alarm will turn on which listed in
the payload, and please arrange battery change or
sensor changed ASAP. You may see the alarm turn
on and off during the time in around 3V, since the
battery voltage is not constant falling in the real
case.

Why the timestamp in the
payload is different to the
timestamp in the server
received time
The timestamp in the payload is the UTC time in
the clock at the sensor, which is time
synchronized during installation with the mobile
app, and there is potential shifting due to no
repeat synchronised with the system. Thus, it is
only being used as reference only.
