Open box Shelly BLU H&T ZB Mocha – 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 Ivory 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. Its discreet design allows it to be placed 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 or cellar, it tracks humidity and warns when it goes outside the range set in the app.
• Mounted in a server room or storage space, it signals temperature variations that may affect the equipment or goods.
• Integrated into an existing Zigbee network, it provides temperature and humidity readings for heating or ventilation automations.
• Used in a greenhouse or next to stored wine, it helps maintain constant conditions, with a battery life of up to 3 years on the CR2032 battery.

Note: Requires a compatible Zigbee hub/coordinator to be connected to the network and controlled from the app - it does not work directly over 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.
