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!

A lot of smart outlets develop problems over time from the inductive surge current on electric motor startup (air conditioner, fridge, dehumidifier). The current ratings in ads are generally for resistive loads. Inductive load limits can be 30% less.

I have a Sonoff S31 on my fridge for about 3 years now for power monitoing and have had no issues. I'm sure the fact I don't switch it on and off and it's locked to stay on on power up helps prolong it's life. If you never switch the load I don't see how it's life could be impacted. But I do have a temp sensor on the fridge so any failures I would be alerted to.
