Shelly Zigbee H&T ZB Temperature and Humidity Sensor (Flesh) (BLUHTZBI)

Zigbee Shelly H&T; Temperature and Humidity Sensor; ZB (Flesh-colored)
Shelly BLU H&T; ZB is a small, energy-efficient environmental sensor that accurately measures temperature and humidity, sending data in real time. It supports Bluetooth 5 (BLE) and Zigbee 802.15.4 connectivity, making it easy to integrate with modern smart home systems. The IP54-rated enclosure protects the device from dust and splashes, allowing it to be used in a variety of conditions, both indoors and outdoors.

Compact design and long battery life
Powered by a single CR2032 battery, the sensor can operate for up to 3 years without needing to be replaced. Its lightweight plastic construction and compact dimensions (37 × 37 × 10 mm) allow for easy installation on any flat surface. The sensor is available in three colors: black, mocha, and ivory.

Automation and precise climate control
The sensor automatically transmits information about air conditions, which can be used to control HVAC devices, humidifiers, dehumidifiers, or fans. It can also activate defined scenes, e.g., by turning on the heating when the temperature drops or ventilation when humidity rises. In addition, the user receives notifications when conditions exceed set thresholds, which helps prevent problems such as mold growth or frozen pipes.

Simple operation and quick setup
The device is operated using a single button and LED, which allow for pairing, resetting, or checking current measurements. It is operated via the Shelly Smart Control app, but a compatible gateway is required for it to work, e.g., Shelly BLU Gateway or devices from the Shelly Plus, Pro, Gen3, and Gen4 series. When used in a Zigbee network, a compatible Zigbee gateway is required.

Security and versatile application
Shelly BLU H&T; ZB guarantees secure data transmission thanks to encryption and is suitable for both home and specialized applications – from climate automation, flood or overheating protection, to greenhouse optimization. The device is the perfect addition to any smart home, offering precise measurements and reliable operation.
