LZW40 4-in-1 Sensors draining battery fast

LZW40 4-in-1 Sensors are draining battery and dying fast. I bought 3. First one drains batter within hours. One of them died and reset is not working. Third one drained in 60 days. Any way to revive these and get them to work as advertised.

Please post your parameter settings and logs from the device. Seems like it is constantly working if it dies in hours. Recommend exclude/hard reset and include and report back.

exclude/hard reset done multiple times.

Is there any followup to this ? One of my sensors is behaving the same way, draining each new battery in 2-3 days. I have done exclude/include plus a hard reset (as recommended above), with no change in the behavior. I also tried a different brand of battery in case I had got some bad ones, but that didn’t help either.

Thanks.
