Shelly BLU H&T ZB Black – Smart temperature and humidity sensor, Zigbee 3.0, battery life 3 years

Shelly BLU H&T ZB Black is a compact temperature and humidity sensor with dual Zigbee 3.0 and Bluetooth 5 LE connectivity, suitable for monitoring the climate in homes, offices or small commercial spaces. The discreet design allows placement on any surface, and readings are sent periodically to the Zigbee hub or to the Shelly Smart Control app via Bluetooth.

IP54 protection against dust and water splashes extends its use beyond the living room, to bathrooms, kitchens, cellars or greenhouses, where humidity changes frequently. In professional settings, the sensor can be used to monitor storage conditions, server rooms or production areas sensitive to temperature changes.

Configurable alerts in the app warn you when the temperature or humidity goes outside the set range, useful for protecting electronic equipment, stored wine or greenhouse plants. The included CR2032 battery offers a battery life of up to 3 years, significantly reducing the need for maintenance.

Please note: Zigbee operation requires a compatible Zigbee coordinator or hub, and Bluetooth-only operation requires a Shelly BLU Gateway or a Shelly device with Bluetooth Gateway enabled.

Practical use cases

• Placed in the bathroom, kitchen or cellar, it tracks humidity and sends alerts in the app when the values go outside the set range.
• Used in a server room or storage space, it monitors the temperature and warns of variations that may affect the equipment or goods.
• Integrated into an existing Zigbee network via the Zigbee hub or coordinator, alongside other smart home devices, or used over Bluetooth with Shelly BLU Gateway or a Shelly device with Bluetooth Gateway enabled.
• Note: For Zigbee operation it requires a compatible Zigbee hub/coordinator; it does not work directly via WiFi.

Technical specifications

With its combination of IP54 protection and extended battery life, BLU H&T ZB remains a reliable solution for monitoring the climate in less hospitable areas of the home, such as the bathroom or the cellar, without frequent maintenance.
