Air things sensors - constant issues

Does anyone else use these sensors and has a decent time with them?

Mine (wave enhance) will drop off and not come back until I change batteries. It seems to be eating brand new energizer batteries within a day or two.

The “good” (Plus with radon) one refuses to do a firmware update. It just stays stuck in the firmware update cycle.

The weird thing is. I set these up on February after spending 500+ for 2 sensors and they were good. I’ve never touched the air things app after the first setup and FW upgrades. Esphome bt proxies are my back channel and I have no issues with other bt sensors (switchbot, etc.) using the bt proxy mesh as their backhaul.

I haven’t reached out to the manufacturer yet. Just seeing if anyone else has these issues all of a sudden? These sensors are less than a year old so they shouldn’t be this bad off.
