WiZ introduces its SpaceSense technology that lets you turn smart lights on and off as you walk around your home. That works without an extra sensor or other accessories, but with the lamps you already have. WiZ uses the WiFi connection of the lamps instead.
WiZ SpaceSense
WiZ, the manufacturer of smart lighting, has proposed a new technology that automatically turns lights on and off. WiZ did this during an online launch event. SpaceSense, as the system is called, works as soon as you have at least two WiZ lamps in a room. The function is available for the existing WiZ lamps that have been launched with WiFi since September 2021 and in time it should also work for Bluetooth lamps from WiZ.
It goes like this. Because you live in the room, you create small disturbances in the WiFi signal with which the lamps are interconnected. This way the WiZ app knows that you are in the room and the lights are switched on. When you leave the room, that too is recognized, and they go out.
