Compact Shelly smart home sensor that accurately measures temperature and humidity in real time and, thanks to Bluetooth 5 (LE) and Zigbee, integrates easily into compatible systems. It offers up to 3 years of battery life, simple installation on a flat surface, and resistance to dust and splashing water – ideal for an apartment, office, or bathroom.
Accurate real-time monitoring of temperature and humidity
Built-in sensors provide accurate temperature and humidity data and help you maintain an optimal climate at home, in the office, or in a greenhouse. You can use the measured values for automations – for example, starting the air conditioner or controlling humidification based on current conditions.
Bluetooth and Zigbee for easy integration
Support for Bluetooth 5 (LE) and Zigbee 802.15.4 provides flexible connectivity to compatible devices and systems. Communication range is up to 10 m indoors and up to 30 m outdoors (depending on conditions).
Long battery life and practical controls
Powered by a single CR2032 battery (included), it provides up to about 3 years of operation. It includes a button for sending current readings, starting pairing, or reset, and a LED indicator for status. Thanks to resistance to dust and splashing water, it is suitable even for more demanding locations.
Shelly BLU H&T ZB is a smart wireless sensor for convenient monitoring of indoor conditions. It regularly sends measured values, so you can automate device operation based on the current situation – for example, start the air conditioner when the temperature is exceeded or control a humidifier/dehumidifier according to humidity.
Humidity monitoring helps prevent mold formation in risk areas (bathroom, basement), and threshold alerts let you respond quickly. The sensor can also detect unusual temperature deviations that may indicate risks such as frozen pipes or overheating.
