Senses water and temperature. Has a siren. When this neat little sensor is paired with our Multigateway, it will notify you immediately if it detects a water leak. Place it by or under your washing machine, dishwasher or in your basement and know that you will be notified in time to minimize the damages a leak can cause in your home.


If you are away, in combination with a connected door lock, you can call a plumber, and let them in no matter where you are. This can help save on costly repairs. In addition to sending a notification to your phone, the sensor will also emit a powerful sound signal.


If you have high flood risks, pairing this up to a water pump using a smart socket might be a good idea.


Placement for this as a temperature sensor is not optimal for thermostat duties, but if placed in your basement you will be able to see if the frost might be getting close to bursting your plumbing with ice.


All connected devices with sirens are connected – if one is triggered, all will be triggered


You need the Wattle Multigateway or the Wattle Premium Mulitgateway to use this device with the Wattle-app.
