The Shelly PLUS H&T is part of the Shelly Blu range of instruments for measuring temperature and humidity. It is compatible with the Shelly Plus and Shelly Pro series, which already have a Bluetooth chip. It uses encryption for communication with remote Shelly devices.

However, if there is no Shelly Plus or Shelly Pro series device in the system, the Shelly BLU Gateway can be used as a gateway to the sensor.

Shelly Blu H&T can be used to detect heat and humidity indoors or outdoors, and additional Shelly devices can be used to send automations or notifications as required. This design is IP 65 certified, making it dust and drop resistant.

Its small size allows it to blend easily into the environment and its discreet appearance offers a wide range of placement options. The sensor is button battery powered and thanks to Blueooth Low Energy it has a long battery life of up to 2-3 years.

According to the factory specification, the range is 10 metres indoors and up to 30 metres outdoors (in an unobstructed environment).

The Shelly Blu Button also offers full compatibility with the new BTHome Home Assistant protocol.

Shelly BLU devices are also compatible with Amazon Alexa and Google Home.
