Water Leak Sensor 4 detects drips from above with its top electrodes and pooling water below with its bottom electrodes. When enabled, its built-in sounder gives a local leak alert. A configurable low-temperature warning helps flag conditions that may lead to freezing.

Works great!
Had a link under a sink. Already had the garage door sensor and hub. Gat a leak sensor for each sink in the house. Tested each with a little water. Heard the alarm, saw it on the app, and got an email. I don't worry about hidden leaks creating mold in my house.

easy setup
Ordered the Hub and 4 water leakage sensors. Easy to set up. Has some questions, support was excellent in understanding and getting to resolution. Would buy again.
