Does anyone have or know of a refrigerator temperature sensor that works with Z/wave?
There are a few on Amazon - search real quick. I don’t know if they’d be compatible with ADC.
What you can do, if you have an extra or can get one cheaply, is to grab a t-stat. Leave it in the off position but it should still tell you the temp wirelessly. Can check the humidity too, but you’ll need to do that at the t-stat.
