Shelly BLU H&T ZB – Bluetooth Temperature & Humidity Sensor (Black)
Overview
The Shelly BLU H&T is a compact, Bluetooth-operated temperature and humidity sensor designed for accurate environmental monitoring in both indoor and outdoor environments. With precise sensing, long battery life, and a rugged IP54-rated enclosure, it is ideal for locations where Wi-Fi sensors are impractical or unnecessary.
Using low-power Bluetooth communication, the Shelly BLU H&T connects to a Shelly BLU Gateway or compatible Shelly Plus, Pro, or Gen3 devices acting as Bluetooth proxies. Once connected, it enables real-time climate monitoring and automation, allowing Shelly systems to respond intelligently to changes in temperature or humidity.
With support for encryption, beacon mode for presence detection, and free historical data storage, the Shelly BLU H&T is well suited for smart climate control, automation scenarios, and condition monitoring in homes, garages, greenhouses, sheds, and outdoor areas.
