Absolutely. I installed one in my kitchen freezer at this date/time: (from the IDE)

I just replaced the battery a month or 2 ago.

Got a link to these? Think I found them but wanted to be sure looks like they have a larger battery.

23

For the Iris or Visonic sensor?

24

Yes for The sensor.

Is this the one? They are on sale at lows at the moment.

Yup, that’s the one. Not a bad price either.

Thanks for the info but the spec sheet shows

Environmental
Operating Temperature: 0° to 40°C

Maybe it last longer because it has a larger battery?

I’m finding the new SmartThings multi-purpose sensors have poor battery life in general. One in refrigerator at 35F only lasts a month or so. New one in my pantry dog food container lasts about 2 months. The older SmartThings multi sensor on my metal garage door lasts many months (through winters in 0F range and summers 90F). Need to make / look for a WebCoRE piston to track my batteries, Between these new sensors and Arlo cameras, seems like I’m changing batteries every week :frowning:

Soldering an external 2 AA battery holder (3 Volts) worked for me. Thank you for the advice!
