### ⭐⭐⭐⭐⭐ Easy to set up
*by A***H on 17 February 2026*

Purchased after a water leak on a copper pipe behind washing machine. Only discovered it when the kitchen floor was covered with water. Bought a set of 3 switchbot sensors, easy to set up, work well when tested with water across the contacts and the app appears to give a timely alert. Good to have but hope not to hear the alarm anytime soon.
