With a humidity meter, you measure the humidity in a room in your home or office. Our humidity meters measure not only the humidity but also the temperature in a room. A humidity meter can be combined with all our smart bulbs and plugs. In the Smart me app, pair this humidity meter to one of our smart plugs and switch a humidifier on/off when a certain value is reached. PLEASE NOTE: A Smart me Zigbee humidity meter only works in combination with a Zigbee gateway (Link ME). Connect multiple Smart me Zigbee products to one gateway.
