For 1 week, the device has been pinging back to the cloud with average humidity value as well as the battery values as recorded in the Google sheets.

The humidity values were pretty consistent from 87 RH% to 92 RH%.

The LiPo battery voltage levels came down steadily from a fully charged value of 4.2V to 3.9V.

I just put in the dehumidifier beside the device. So let's see whether the humidity levels change at all.
