A water leak detector is used when you want to be warned in case of leakage. If the sensors in this water leak detector come into contact with water, you will receive a message in the Smart me app. Install a water leak detector near a washing machine, dishwasher, bathtub or boiler to prevent a disaster. The water leak detector can be combined with all our smart bulbs and plugs. For example, turn off the washing machine or make a lamp flash red if there is a leak. PLEASE NOTE: A Smart me Zigbee water leak detector only works in combination with a Zigbee gateway (Link ME). Connect multiple Smart me Zigbee products to one gateway.
