Open box Shelly BLU H&T ZB Ivory – Smart Temperature and Humidity Sensor, Zigbee 3.0, Battery Life 3 Years

What does "open box" mean?

Open-box products are returned products with opened or damaged packaging, but fully checked from a technical point of view and completely functional. They come with the same warranty as new products.

Shelly BLU H&T ZB Mocha is a compact temperature and humidity sensor with dual Zigbee 3.0 and Bluetooth 5 LE connectivity, suitable for monitoring the climate in homes, offices or small commercial spaces. The discreet design allows placement on any surface, and readings are sent periodically to the Zigbee hub or to the Shelly Smart Control app via Bluetooth.

IP54 protection against dust and water splashes extends its use beyond the living room, to bathrooms, kitchens, cellars or greenhouses, where humidity changes frequently. In professional settings, the sensor can be used to monitor storage conditions, server rooms or production areas sensitive to temperature changes.

Configurable alerts in the app warn you when the temperature or humidity goes outside the set range, useful for protecting electronic equipment, stored wine or greenhouse plants. The included CR2032 battery offers a battery life of up to 3 years, significantly reducing the need for maintenance.

Please note: Zigbee operation requires a compatible Zigbee coordinator or hub, and Bluetooth-only operation requires a Shelly BLU Gateway or a Shelly device with Bluetooth Gateway enabled.

Practical use cases

• Placed in the bathroom, kitchen or cellar, it tracks temperature and humidity and sends an alert when the values go outside the range set in the app.
• Used in a server room or storage space, it warns in time when the temperature rises above the desired limit.
• Mounted in a greenhouse or near stored wine, it helps maintain a constant climate for plants or bottles.
• Note: For Zigbee operation it requires a compatible Zigbee hub/coordinator, and for Bluetooth operation a Shelly BLU Gateway or a Shelly device with Bluetooth Gateway enabled - it does not work directly via WiFi.

Technical specifications

With its combination of IP54 protection and extended battery life, BLU H&T ZB remains a reliable solution for monitoring the climate in less hospitable areas of the home, such as the bathroom or the cellar, without frequent maintenance.
