About this product
Shelly H&T Gen3 Matte White is a Wi-Fi temperature and humidity sensor with a large e-ink screen that shows current readings without reaching for your phone. The matte white casing blends discreetly into a living room, bedroom or office, and mounting on the included stand or on a wall takes only a few minutes.<br><br>The device connects directly to a 2.4 GHz Wi-Fi network and reports to the Shelly app without a separate hub. On batteries the sensor wakes every minute to measure and sends data when temperature changes by 0.5 degrees C or humidity by 5%, while the screen refreshes at a 0.2 degrees C or 3% difference.<br><br>Standard power is 4 AA (LR6) batteries with about one year of runtime, and for continuous use you can connect a USB-C cable. With scenes, webhooks and MQTT, H&T Gen3 can start a humidifier, boiler or fan whenever readings drift outside the range you set.
