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.

joining the fast draining battery group. Any fixes?
Curious if those with draining batteries are replacing when they get low, or are waiting until the batteries actually die? My LZW60 looked like it’s battery was ‘draining’ but has held steady at the ~30% range now for several months. If your batteries are actually dying and the device turns off, then I’m not sure what to do there. But if not that, be aware that the battery level may be slightly lying to you and may be OK for a while at what is seemingly a low battery level.
mine died in a week… no power at all
I’ve had this issue once in the past where a sensor would actually drain batteries in a few days. Never figured out the cause, but the fix for me was a simple factory reset and exclude, before re-including it on my network. Since then, it’s been perfectly fine.
One weird thing I’ve noticed as of updating to firmware 2.5 is that 3 of my 4 LZW60’s are reporting critically low batteries (0%). Funny thing is, pre update (on firmware 2.3) they were reporting 100%, then immediately post update it reports 0%. I even threw in a new battery just in case to see, and that one reports as 1%. This has been the case for about a month and a half now and none have lost power. I know one has reported back that there is no power at all in their sensor, but I’m curious if others on firmware 2.5 are having the same problem?
Did you include with 3x or 5x? 5x set the device as a repeater. This should only be used when USB powered as it uses more power. The device I included as a repeater shows 0% batter.

Just in case for mine I excluded it and re-included it one more time with 3x presses. Still reporting as 0% even after adding a new battery.
