The Shelly BLU Door/Window ZB is a smart Bluetooth and Zigbee sensor for doors and windows, that detects open/close status and measures light levels.
The sensor detects openings/closing instantly and triggers your home automation. Strengthen security, automate lighting, or track access. The compact design installs easily on doors, windows, gates, garage doors, and more - blending into any interior.
If you have Shelly Gen 3/Gen4/Pro devices in your home already, they act as a gateway for Shelly BLU devices, requiring no other receiver or gateway - or grab a Shelly gateway if not! Once connected to your Shelly network, you can use it with your Shelly smart home ecosystem, including the Shelly Smart Control app - or link it with a popular home automation software such as Home Assistant via a Raspberry Pi!
Currently only available in white, however black and brown (wood-effect) variants are expected at some stage.
Give a warm welcome to your loved ones when entering your home. When placed on the front door, Shelly BLU Door/Window ZB can turn on the lights when the door is opened.
Shelly BLU Door/Window ZB can also contribute to your energy efficiency efforts. By connecting it to other devices, you can automate the adjustment of heating, cooling, or lighting based on the door or window open state. For example, when a window is opened, the system can automatically turn off the heating to conserve energy.
Always be informed of any unwanted guests! Simply place Shelly BLU Door/Window ZB on your front door, balconies, windows, or garage door, and receive a notification if someone opens them while you are away. But that’s not all - Shelly BLU Door/Window ZB can be used as part of your security system using automation scenarios or scenes. It could activate other devices to protect your home when unexpected activity occurs at your premises.
