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 currently have a similar setup (ESP32, BLE Sensors with ESPHome). Only problem is my sensors are Cr2032 and they go through a shit ton of batteries.
Is there a write up somewhere on how to get these working? I’d like to replace all mine!
