The Shelly BLU H&T Battery Sensor is a compact, water and dust resistant device that can accurately measure indoor and outdoor temperature and humidity levels. You can use the Shelly Smart Control mobile app, the BTHome protocol, or various smart home platforms (Google Home, Tuya) to conveniently control the sensor. Connecting the sensor to other smart devices allows full automation of climate control, including the creation of automated scenarios (requires a hub). If the temperature or humidity reaches the set limits, the sensor immediately sends a notification to your phone, allowing you to react in time to prevent any problems. In addition, the recorded data is stored in the cloud free of charge (for 1 year) so that it can be analysed at any time. Reliable wireless connectivity between the sensor and your phone and other devices is provided by Bluetooth 4.2 and the encrypted Zigbee protocol. Shelly Blu H&T has a very compact size and is equipped with a CR2032 button cell battery that lasts up to 3 years.


To use the product's smart features, you need to add the device to the manufacturer's app. For more information about the application (name, supported OS, supported languages) and how to add a device to the application, please refer to the product manual.

The sensor has a very durable and compact design, so it can be installed unobtrusively both in the home and outdoors. Fully integrated into the smart home ecosystem, the Shelly Blu H&T sensor can automatically adjust the performance of dehumidifiers, heaters, sprinklers or air conditioners based on the current temperature and humidity. This function is useful, for example, in greenhouses where you can optimise the growing conditions by regulating the irrigation and ventilation systems. The sensor can monitor temperature from -20 to 60 °C and humidity from 0 RH to 100% RH.

Thanks to built-in temperature and humidity sensors, Shelly BLU H&T enables accurate measurement and real-time reporting of current climate data via an app. Set up notifications when humidity or temperature values reach pre-set limits. Thanks to this feature, you can prevent various inconveniences such as mould formation or the risk of water freezing in the pipes. In addition, the detection of abnormal changes in temperature and humidity can also help you detect an emerging fire or flood.

The Shelly Blu H&T humidity sensor comes in three colour options (Ivory, Mocha and Black) designed to blend in with both indoors and outdoors. A powerful battery with a lifetime of up to 3 years ensures reliable area monitoring with the option of more frequent updates. With an IP54 rating, the device can withstand both dust and water, making it the first Shelly sensor of its kind to operate reliably even in very harsh environments. Whether you install it in a bathroom, greenhouse or damp cellar, you can be sure that the device will always work reliably.
