Learned my lesson after a trip last week… I have sensors for nearly everything, but somehow totally forgot about the Fridge / Freezer.
A power outage made my fridge lose it’s mind and turn off cooling, even after it powered back up. Unplug / replug seems to have fixed it, but all the food was spoiled when we got home. Simple $10 temperature sensor could have saved everything!
I’ve been wanting to do this for awhile after having problems with the cooling coils freezing over. My question is, what sensor would you use for this? A battery-powered one would need to be recharged and a wire running into the fridge would break the seal
I bought a battery-powered (2xAAA) zigbee temperature/humidity sensor about 6 months ago and haven’t replaced its batteries yet.
A battery powered ZigBee one should last for at least a year…
