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 got this yolink setup June 2022 and it works great. Have not changed the batteries either. The system has notified me a few times like if I’ve put a case of water and beer in. I don’t think this integrates with HA I just needed something that worked and not trying to rig up something. Another must have are water sensors. I’m running 13 govee water sensors and been notified few times also.

Water sensors are the big one for me! I have a mixture of old SmartThings ones, and cheap ThirdReality branded ones (that seem to work fine still!)
My govees were cheap and I needed a ton of them, 13. They got great reviews. Wish they would integrate w HA but not currently without trying with rf reader and it’s too important for me I didn’t want to risk this. Last year went to Hawaii for 2 weeks and this is the reason I bought this stuff.
The fridge and water sensor stuff is to important and should have had it years ago.
