Climate Control Mold and Mildew Prevention Real-time Notifications Optimized Greenhouse Conditions Smart Scene Control Maintain a comfortable environment by adjusting your smart heating, ventilation, and air conditioning to the temperature and humidity levels collected by BLU H&T. Spaces with high humidity levels, such as bathrooms, are often exposed to mold and mildew. By tracking the humidity levels and activating ventilation (when necessary), you can prevent such danger. Set thresholds in your Shelly app and get notified every time a temperature or humidity level is surpassed. Prevent damages, such as frozen pipes for example. Enhance greenhouse plant growth by fine-tuning watering systems and ventilation in response to changes in the temperature and humidity levels. Create smart scenes, pairing BLU H&T with your dehumidifier or heater, and control them according to the ambient temperature/ humidity levels.

Review: Works perfect for this custom application - Working great for 6 months now monitoring the temperature and humidity of my loft that turns on and off a Shelly smart socket with an extractor fan. Condensation in the loft solved👍🏻 Note: you will need the Shelly Bluetooth usb dongle to connect it to your WiFi network for off site access. Review: Excellent sensors. - Excellent sensors. Very long battery life using BLE technology. Fairly accurate for a sensor at this price point. Usual high Shelly quality. Operates well in challenging situations such as inside a fridge. Works with the Shelly app or with Home Assistant using a Bluetooth proxy such as the one built in to many Shelly devices. Battery life is so long on these sensors that the manufacturer ships them from the factory with the battery already installed and the sensor active. I use Home Assistant and the sensor was automatically detected while still in the unopened package just after the postman pushed the package through the letterbox. Can’t ask for much more than that! ## Technical Specifications | Specification | Value | |---------------|-------| | Battery description | 1 x 3V CR2032 | | Brand | Shelly | | Colour | Black | | Item weight | 13 Grams | | Mounting type | Surface Mount | | Product dimensions | 37W x 37H millimetres | ## Product Details - **Battery description:** 1 x 3V CR2032 - **Brand:** Shelly - **Colour:** Black - **Item weight:** 13 Grams - **Product dimensions:** 37W x 37H millimetres ## Images ![Shelly BLU H&T Black - Bluetooth Temperature and Humidity Sensor, Smart Thermometer and Hygrometer for Indoor/Outdoor, IP54 Certified, Data Storage, Beacon Mode, Gateway Required - Image 1](https://m.media-amazon.com/images/I/81f3mjTE43L.jpg) ![Shelly BLU H&T Black - Bluetooth Temperature and Humidity Sensor, Smart Thermometer and Hygrometer for Indoor/Outdoor, IP54 Certified, Data Storage, Beacon Mode, Gateway Required - Image 2](https://m.media-amazon.com/images/I/51h7j23OtYL.jpg) ![Shelly BLU H&T Black - Bluetooth Temperature and Humidity Sensor, Smart Thermometer and Hygrometer for Indoor/Outdoor, IP54 Certified, Data Storage, Beacon Mode, Gateway Required - Image 3](https://m.media-amazon.com/images/I/71r2N1atepL.jpg) ![Shelly BLU H&T Black - Bluetooth Temperature and Humidity Sensor, Smart Thermometer and Hygrometer for Indoor/Outdoor, IP54 Certified, Data Storage, Beacon Mode, Gateway Required - Image 4](https://m.media-amazon.com/images/I/41846O+QhxL.jpg) ![Shelly BLU H&T Black - Bluetooth Temperature and Humidity Sensor, Smart Thermometer and Hygrometer for Indoor/Outdoor, IP54 Certified, Data Storage, Beacon Mode, Gateway Required - Image 5](https://m.media-amazon.com/images/I/7129RSqTvVL.jpg) ## Available Options This product comes in different **Color** options. ## Questions & Answers **Q: Shelly BLU H&T inclusion failed.
