Don't forget Temperature Sensors for your Fridge! (lemmy.world)

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!

These are the ones I got, just because they are only $9 each, with a display as well. Each one has 2x AAA battery, so I'd expect they'll last quite a while. HA also reports on battery level - https://www.amazon.com/dp/B0872X4H4J

They are bluetooth, but I already had an ESP32 for other sensors. Seems to work great w/ Home Assistant / ESPHome so far!

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!

If you already have ESPHome and Bluetooth proxies setup, the Govee sensors should be auto discovered by Home Assistant as soon as you put the batteries in!

It is the Govee Bluetooth integration, I was actually amazed how simple the setup was. Didn't even have to install the Govee app. Definitely give them a try, the price is right!
