Aqara Water Leak Sensor
A coin-sized, battery-powered Zigbee leak sensor for under sinks and behind washing machines - but it needs an Aqara hub before it can alert you.
4.1 / 5
★★★★★ ★★★★★ Highly recommended
Strengths
- Completely installation-free - a battery puck you place on the floor, ideal in a rented flat
- Very sensitive detection with near-instant alerting when water touches the contacts
- IP67 housing survives actually being flooded
Watch outs
- Requires an Aqara hub before it can do anything - it is not a standalone Wi-Fi device
- On third-party Zigbee setups (ZHA/Zigbee2MQTT) users report drop-offs and re-routing quirks that can need manual fixing
- Coin-cell battery rather than easily-swapped AAs
- Model SJCGQ11LM
- Protocol Zigbee
- Hub required Yes - an Aqara Zigbee hub (or an existing Zigbee2MQTT/ZHA setup for advanced users)
- Battery CR2032 coin cell
