About this product
Shelly H&T Gen3 Ivory is a smart temperature and humidity sensor that connects straight to your home Wi-Fi network without a separate hub. Its e-paper display always shows the current readings and only draws power when refreshing, so you can check temperature and humidity at a glance, even without reaching for your phone.<br><br>The device can run on 4 AA (LR6) 1.5 V batteries for roughly a year, or be powered continuously through its USB-C port, in which case it reports data to the cloud more often. With Wi-Fi 802.11 b/g/n and Bluetooth 4.2 it pairs quickly with the Shelly Smart Control app and sends notifications when temperature or humidity cross the thresholds you set.<br><br>The compact 70x70x26 mm body in a warm Ivory finish blends discreetly into a living room, bedroom or office. Through scenes and automations the sensor can trigger a thermostat, humidifier or dehumidifier, and it works with Home Assistant, Google Home, Alexa and SmartThings.
