With Ambient Sensing, groups of Zigbee devices—like smart lights—can work together to detect motion in a given area.

The latest Zigbee feature can give you presence-sensing smart lights with just a firmware update and no additional hardware

The Connectivity Standards Alliance teased an update to the Zigbee protocol The update will let Zigbee devices like Hue lights work as occupancy sensors We don't yet have a timeline for when the feature might be rolled out Your Philips Hue lights could soon get a lot smarter thanks to a free firmware update that would let them do double-duty as occupancy sensors.

The Connectivity Standards Alliance (CSA) has introduced a feature named “Ambient Sensing” in a recent video announcement. There aren’t many details on this new feature, but from the video we’re assuming it utilizes Zigbee technology to detect presence within a room by analyzing interference in connection signals.
