The Shelly BLU H&T ZB is a waterproof and dustproof wireless temperature and humidity sensor that offers both Bluetooth and Zigbee connectivity. Ideal for indoor comfort monitoring and automation: based on the measured values, scenes can be started, notifications can be sent, and other Shelly devices can be controlled.

The sensor can be used with a gateway in the Shelly ecosystem (with the exception of Shelly BLU Gateway or any Shelly Plus/Pro/Gen3/Gen4 device - sensors), and can be connected to any compatible Zigbee gateway in a Zigbee network. The two radio connections ensure flexible installation and stable, reliable operation.

Its IP54 protection and the long battery life of up to 3 years ensure low-maintenance, reliable operation. In the Shelly Smart Control application, data can be tracked with graphs, history and .CSV export.
