The compact Shelly H&T ZB environmental sensor precisely measures temperature and humidity in real time and communicates via Bluetooth 5 and Zigbee 802.15.4. With IP54 protection, it is suitable for both indoor and outdoor use, offers long battery life up to 3 years on a CR2032, and easily integrates into your smart home for automating heating, ventilation, or humidification.
Maintain the ideal climate at home or at work with the Shelly H&T ZB sensor in an elegant ivory color. The device provides accurate temperature and humidity readings, sends data instantly, and thanks to Bluetooth LE and Zigbee support, it easily connects to your smart home systems. The durable IP54 enclosure protects against dust and splashing water, making it suitable for bathrooms, utility rooms, and sheltered outdoor areas.
Thanks to extremely low power consumption, it lasts up to 3 years on a single CR2032 battery. Compact dimensions of 37 × 37 × 10 mm allow discreet installation on any flat surface. A single button and LED make pairing, resetting, and quick status checks easy.
