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!

Flood/water sensors:

  • Hot water heater
  • Under kitchen sink
  • Behind dishwasher
  • Under clothes washer

Smart valve on mains water supply so you can automatically cut off water to the entire house if any of your leak sensors alert.
