Signify has released the SpaceSense motion detection feature to its WiZ smart lighting system, enhancing users’ daily convenience. The motion detection technology doesn’t require a sensor as it all works from the WiZ app V2.

The SpaceSense feature is a never-seen-before innovation in the consumer lighting industry. It uses WiFi signals that are already present in the room to detect motion – without the need for dedicated sensors and batteries.

WiFi signals are slightly disturbed when people move around in a room, like a ripple in a swimming pool. By measuring the slight deviations in signal strength caused by those disturbances, the WiZ lights can determine if there is an object moving in the room.

The detection is omnidirectional and doesn’t require a line of sight during installation, like in the case of a traditional motion sensor. The system’s sensitivity can be adjusted, for example, to prevent your pets from turning the lights on and off while running in and out of the room. You simply install at least two lights per room and connect them with the WiZ app V2. The new feature is completely opt-in so all WiZ users can decide whether they would like to use it or not.

“For many users, the need for extra hardware to enable motion detection in their system felt complex, expensive and cumbersome. Now, for the first time ever, SpaceSense takes those hurdles away, opening up automation and other smart lighting advanced benefits to everyone.” WiZ head of software product management Danny Lousberg says.
