Shelly Wave (Long Range) H&T humidity and temperature sensor, white

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.
