Temperature sensors for freezers

Yes, the battery status dropped rapidly for me as well, all the way down to 0%, but the sensor continued to operate at 0% battery for over 12 months til it stopped reporting.

I am hoping the same thing happens for me. But the original battery went down to 10% then disconnected from hub.

FYI, I have had batteries I got from amazon that’d stop working with status well above 50% (at room temp), while the same sensor with batteries from other more reputable sources would continue to operate with battery status well below 50%. So make sure you get good batteries.

May be swap a different sensor if you have one being used elsewhere. I guess it’s possible there’re part to part variations that the sensor you’re using is more sensitive to the quality of the power source.

Good luck.

I guess it is a wait and see thing. My next thing is get a remote battery case and solder on two leads from the sensor. My concern is the wires through the door seal.

UPDATE: Battery said 10% then it stopped reporting. I then took the sensor out of the freezer let it warm up and then removed the battery and put it back in. It showed 75% battery. I decided to solder two leads to the sensor with flat wire then connected an external 2450 battery holder and battery outside the freezer and all is working and reporting.

For even longer battery life, you could use a pair of AA batteries in series. A little larger, but if you can hide it…?
