Detected leak before any damage

I picked up the Yolink starter kit earlier this year and installed the sensors under the sinks and behind the fridge. About four months later, I heard a beep in the kitchen and traced it to the sensor behind the refrigerator. It had detected a small leak coming from the nearby dishwasher. I shut off the water and made the repairs. Thankfully, the sensors caught the leak long before any real damage could occur. I later bought the three-sensor expansion pack and installed those under the remaining sinks in the house and by the hot water heater.

Highly recommended!

Installed these in the secondary condensation pan of my HVAC air handlers. Had a clogged condensation line in one which resulted in the secondary pan filling with condensate. YoLink sensor alerted me and saved the day. I also have their temperature/humidity sensors installed on the same hub in my refrigerator/freezers which have proven to be invaluable.

Best Water Leak Sensors Ever!

I love these sensors so much! It gives you a silent alert on your phone when there's a leak and being able to label each sensor makes it easy to find which location is leaking. My sensor found a leak under my kitchen sink extremely fast before any damage was created. This was exactly what I was looking for. Assembly is very explanatory to configure. Monitoring your sensors via the app is super user friendly.
