Use a Zigbee sensor if you want to know the temperature in your home or receive a notification on your smartphone in case of leakage. Does a door open unexpectedly or do you want smart bulbs to turn on automatically when motion is detected? A Zigbee sensor is the solution. A Zigbee sensor can be combined with all our Smart me bulbs and smart plugs. In the Smart me app, pair a Zigbee sensor with a smart bulb and have it automatically turn on when you enter your home or visit the toilet. PLEASE NOTE: A Smart me Zigbee sensor only works in combination with a Zigbee gateway (Link ME). Connect multiple Smart me Zigbee products to one gateway.
