Help with aqara temperature sensor

Hi all,
I have an aqara temperature sensor im my balcony for measuring the outdoor temp. and humidity. It was working fine but in low external temperatures was not so accurate. So I tried to calibrate it using the below method (through home assistant)

Calibrating temperature sensors using the deCONZ service (

Although this method fixed the problem, the sensor started to drain the battery. In a few hours the battery drained from 80% to 0%. I tried a new battery and in half an hour was at 30%!

I tried to reset it, and though dencoz app


and by holding the button for 5 sec, but the problem remains. I lost 3 batteries until now.

Is there a way to fix it or should I just sent it to garbage?
