Planning on adding a Smartthings multipurpose sensor to my back door. I want to install it on the storm door and not the interior door. My storm door routinely gets frost on it so the sensor will be in sub freezing temperatures routinely, especially this time of year. Will this have any negative effects on the sensor itself? How about battery life?
In regards to batteries, are the Panasonic CR2450 still the preferred battery for replacement? I have a sensor on my front door that has been up and running for over a year. Getting down to 70% battery and I’ve read at about 66% they die. So would like to get the battery swapped out on that one before it dies. FWIW, I’m not sure if I have the “old” or “new” sensors. They were all purchased in October of 2017.
