When it comes to monitoring temperature and humidity, Shelly has accustomed us to highly accurate sensors, but they often worked "in the background." If you wanted to check the data, you had to open the app or build a complex dashboard.

The new Shelly BLU H&T Display changes the game. It combines the efficiency of Bluetooth Low Energy (SBC) technology with the excellent readability of an e-paper screen, giving you a compact, elegant, and ultra-power-efficient climate terminal.

🏗️ Hardware and Design: E-Paper Technology Driven by Efficiency 🤓

Unlike classic LCD screens, Shelly chose a much smarter solution for their new sensor in the BLU lineup:

• E-Paper Display (Electronic Ink): It only consumes energy when the information on the screen changes. This means a perfect viewing angle (even in direct sunlight) and a massive battery autonomy measured in years. 🔋

• Bluetooth Protocol (Shelly BLU): The device is part of the new line of low-consumption Bluetooth sensors. It doesn't crowd your router's Wi-Fi band and transmits data instantly. 🐝

• Minimalist Design: Clean white body, sharp lines, and compact dimensions—it fits perfectly on a nightstand, desk, or can be mounted directly on the wall.

🧠 How Does It Work in Your Smart Ecosystem?

To collect data from the Shelly BLU H&T Display and use it in complex automations, you need a "gateway." The excellent part is that you don't need to buy a dedicated hub:

• Any Shelly Gen3 or Plus Device Acts as a Bridge: If you already have a Shelly Plus 1 relay, a Shelly Plug S Gen3, or any new-generation wall switch, they have built-in Bluetooth and will act as a gateway for your display. 🎛️

• Local Control and Zero Latency: Climate data is transmitted directly within the local network. Automations trigger instantly, without depending on an internet connection or cloud servers.

⚡ Smart Climate Automations

Thanks to the sensor's precision, you can create advanced scenarios for comfort and energy saving:

• Ventilation Management: IF the humidity in the bathroom detected by the Shelly BLU H&T exceeds 65%, THEN the in-wall relay automatically triggers the exhaust fan. 💨

• Bedroom Comfort: IF the temperature drops below 20°C at night, THEN turn on the space heater connected to a smart plug. 🌡️🔥

• Sun Protection: Correlate sensor data with the sun's position. If the temperature rises rapidly in the office, you can command the motorized blinds to roll down.

✅ Technical Verdict: Is It Worth Adding to Your Setup?

The Shelly BLU H&T Display is an excellent upgrade for anyone wanting immediate visual control over a room's climate without giving up the benefits of the Shelly ecosystem. It is discrete, has remarkable autonomy thanks to the e-paper screen, and perfectly expands the local Bluetooth mesh that Shelly is developing so intensely.
