About this product
The Shelly BLU H&T ZB Ivory is a miniature temperature and humidity sensor (37x37x10 mm, 13 g) designed for discreet monitoring of the indoor microclimate.

Zigbee integration requires a Shelly hub from the Plus, Gen3, Gen4 or Pro series; in Bluetooth mode, reporting to the app and cloud is handled through a Shelly BLU Gateway.<br><br>A single included CR2032 battery delivers up to 3 years of operation, while the wireless range reaches 10 m indoors and 30 m outdoors. Readings can trigger scenes and notifications for climate control and mold prevention.
