Temperature and Humidity Sensor Shelly BLU H&T ZB Black — wireless Zigbee smart sensor

The Shelly BLU H&T ZB Black is a compact wireless Zigbee temperature and humidity sensor intended for indoor environmental monitoring. It measures ambient temperature and relative humidity, transmits readings to Zigbee-compatible hubs and home automation systems, and is suitable for continuous monitoring, HVAC adjustment and energy-conscious smart home setups. The matte black housing and small footprint allow discreet placement on shelves, walls or near equipment.

Advantages

The device provides continuous remote monitoring of temperature and humidity over a Zigbee mesh network, enabling integration with a wide range of smart home controllers. Its wireless operation removes the need for direct wiring and allows flexible positioning. The sensor supports automated actions based on measured values, such as climate control or alerts, and its compact design minimizes visual impact in living spaces.

Suitable for

• Indoor climate monitoring in living rooms, bedrooms and offices
• Integration with Zigbee smart home hubs for automation and scenes
• HVAC control and temperature-based rules
• Humidity monitoring in basements, utility rooms and near appliances
• Data logging and trend tracking via compatible platforms

When it may not be suitable

The Shelly BLU H&T ZB Black is designed for indoor use and is not rated for prolonged exposure to outdoor weather or direct water contact. It is intended for relative humidity and temperature sensing and does not include built-in flood detection or air quality sensors. Large industrial environments with extreme temperatures or corrosive atmospheres may require industrial-grade sensors with broader operating ranges.

Key specifications

• Measured values: ambient temperature and relative humidity
• Wireless protocol: Zigbee (compatible with Zigbee hubs and controllers)
• Power: battery-powered for wireless placement
• Form factor: compact, wall- or shelf-mountable enclosure in black finish
• Use environment: designed for indoor residential and commercial spaces

How to use

Place the Shelly BLU H&T ZB Black in the desired indoor location away from direct heat sources and drafts for accurate readings. Pair the sensor with a Zigbee-compatible hub following the hub’s device inclusion procedure; once joined, configure reporting intervals and automation triggers in the hub or supported app. Replace batteries according to the device’s battery level notifications and keep firmware updated through compatible management tools to maintain performance and security.

What to consider before purchase

• Ensure your smart home hub or controller supports Zigbee devices and is compatible with Shelly sensors
• Confirm indoor placement options and expected measurement range for your use case
• Check battery type and expected battery life to match maintenance preferences

Usage recommendations

For most accurate results, install the sensor at breathing height in living spaces or near the equipment to be monitored, avoid mounting near heat sources or windows, and configure automated thresholds in your Zigbee hub to trigger HVAC adjustments or notifications when values move outside desired ranges.
