Here’s the tech that could turn millions of Zigbee light bulbs into motion sensors with a single update

In development for several years, Zigbee ambient sensing could turn existing Zigbee-powered lights, switches, and plugs into motion sensors.| Image: Ivani Lights that turn on when you walk into a room and turn off when you leave are one of the most desirable smart home features. But you need to buy additional hardware like motion sensors to make this “magic” happen. A new ambient sensing technology called Sensify could make this easier by turning your light bulbs into motion sensors.
