Shelly H&T Gen 3 WiFi Controlled Temperature and Humidity Sensor Black

Shelly H&T Gen3 is a battery-powered Wi-Fi temperature and humidity sensor with an e-paper display and built-in clock. This black version provides local environmental readings while also making temperature and humidity data available for connected monitoring and smart-home automations.
It can operate from four AA batteries for approximately one year, depending on battery quality, environmental changes and network conditions, or from USB-C power for more frequent measurement and reporting. Wall and tabletop placement are both supported.
