Battery powered Pro Mini - Si7021 loses connection with gateway after ~6hrs
-
Hi all,
I'm running a Pro Mini on 1Mhz with a Si7021 sensor on 2x AA NiMh batteries (~3.6V). It all works fine for around 6hrs before it loses connection with the gateway it seems. It doesn't update anymore which results in a flatline in Home Assitant. Upon pressing the physical reset button on the Pro Mini everything goes back to normal; Temp/Hum are reported accurately every minute. The mysgw.log does not show anything strange, it just stops showing data from the specific node. I ran the Pro Mini on a steady 5V input which resulted in the exact same behaviour. Other than changing the freq. the hardware of the Pro Mini remains unchanged.
What can be the problem? How can I make sure it doesn't lose connection.
