What are you seeing? I've been checking voltage and temp, and using beacons instead of MQTT, which is supposed to be similar if not better, but I saw 18 days with the new modules. My batteries may have been crap though. I just got a batch of Energizers in now. Yesterday I changed my code to use SetLowPowerMode(120) in the boot function, which may or may not have been the default, and also lowered the beacon rate to 30 seconds from 10.
