Connect using Bridge

Because the sensor is battery powered, you can place it anywhere in your house. Due to the low power Bluetooth connection, the battery will last over a year. In order to control the device, you need to connect the sensor to a Bluetooth Bridge. This Bridge can support all your sensors in your house to create a complete smart home experience.

Why does the Smart Sensor need a Bluetooth Bridge?

Because the Smart Sensors operate on batteries, a WiFi connection would drain the battery too quickly. The Bluetooth Low Energy consumes almost no energy, because of this the battery of the sensor can last up to one year. To be able to see the status of the device from anywhere on your phone, the sensor needs to be connected to the internet via the Bluetooth bridge.
