Shelly H&T Gen 3 WiFi Controlled Temperature and Humidity Sensor White
Shelly H&T Gen3 is a battery-powered Wi-Fi temperature and humidity sensor with an e-paper display and built-in clock. This white version provides an at-a-glance local read-out while also reporting measurements to connected Shelly services and integrations for comfort monitoring and climate-related automations.
It can run from four AA batteries for approximately one year, depending on conditions, or from USB-C power for more frequent measurement and reporting. Wi-Fi connectivity, an embedded web interface and wall or tabletop mounting options make it suitable for bedrooms, living areas, offices and other indoor spaces.
