There are loads of 'put them in the fridge/freezer' temp sensors out there, made just for this. I did buy lithium AA batteries (which work down to -40C even) for the sensor end.
My thoughts are, these things are special built, and only wake every few minutes or so to burst send. Batteries tend to last a couple of years (but with the lithium ones!), and I get beeeeps from the receiver if it dies.
(Not knocking your solution, it gives you more flexibility)
- scottlamb 1y agoI saw a few that were wired with cords that seemed more intrusive than the telephone cord I tried, so I went my own way. And most of them didn't seem to be something I could connect to Home Assistant.
