The Shelly Wave H&T is a battery-powered temperature and humidity sensor that communicates via the Z-Wave Long Range protocol, helping you ensuring optimal indoor air quality and moisture levels. It's elegant and compact design allows it to be placed anywhere, and the device features a long battery life (~1‑2 years with a CR123A battery). It integrates easily with any Z-Wave hub, supports automatic communication, firmware updates, and SmartStart functionality. This product is part of the Shelly Wave (Z-Wave) series and differs from the traditional Wi-Fi-based H&T family: it uses Z-Wave Long Range instead of Wi-Fi, making it compatible with a different smart home ecosystem.
Shelly is best known for its smart home devices (relays, sockets, sensors) that offer high compatibility and support for open-source platforms (such as Home Assistant and Homey) via MQTT. Their product range includes wireless relays, Wi-Fi and Z-Wave protocol sensors, as well as various power monitoring and control modules.
