Spots a water leak on the floor and reports it to the hub at once.

A wireless water leak detector that sits flat on the floor. The moment its sensor touches water it alerts the alarm hub over the 868.0 MHz–868.6 MHz band with AES128 encryption. The IPX5 casing stands up to wet rooms.

Water leakSensor

CR123A × 1Power supply

3 yearsBattery life

IPX5Protection Grade

-10 °C ~ +55 °COperating Temperature

Key features

Stable wireless linkIt runs two-way with frequency hopping and also detects jamming.

Ambient temperatureIt shows the temperature where it sits and triggers an overheating alarm.

Adjustable sensitivityIt changes trigger sensitivity to suit the installation spot.

Low consumptionIt draws 28.5 µA in operation and climbs to 5.8 mA during an alarm.

Cloud updateIt pulls firmware from the cloud and falls back to the previous build when an update stops halfway.

The stated 3-year battery life assumes one trigger per day.
