Philips Hue Plans To Make All Your Lights Motion Sensors
Philips Hue is rolling out MotionAware, a new feature that turns its smart bulbs into motion sensors using radio-frequency (RF) Zigbee signals. The upgrade works with most Hue bulbs made since 2014, but requires the new $99 Bridge Pro hub to enable. The Verge reports: To create a MotionAware motion-sensing zone, you need Hue's new Bridge Pro and at least three Hue devices in a room. It works with all new and most existing mains-powered Hue products via a firmware update. That includes smart bulbs, light strips, and fixtures. Portable devices, such as the Hue Go or Table Lamp, and battery-powered accessories, such as Hue switches, aren't compatible. Neither is Hue's current smart plug. [...] "All of the functionality you get with our physical motion sensors -- including turning on when motion is detected or off when there's been no movement for a certain amount of time -- can be configured on motion-aware motion events," says George Yianni, Hue CTO and founder, in an interview with The Verge. "We've done something that's quite a lot better than what else is out there." MotionAware is occupancy sensing, not presence sensing; it requires movement. Yianni says it's comparable to the passive infrared sensing (PIR) Hue's physical sensors use. This means it can be triggered by pets or other motion. A sensitivity slider in the app helps fine-tune detection. According to Yianni, a key benefit over PIR is that a MotionAware zone can cover a larger area than a single PIR sensor, and it's also not limited to line of sight. MotionAware can't sense light levels, which Hue Motion Sensors can, but you can pair a light sensor to a motion zone to feed it that data. The positioning of the lights will also play a role in determining the effectiveness of the motion sensing. "We recommend that the lights surround an area which will roughly define the detection area in which motion will be detected," says Yianni. "It will sense around the lights and in the broader room thanks to reflections, but detection reliability will depend on lots of factors." Beyond lighting automation, MotionAware can also integrate with Hue Secure, Hue's DIY security platform that includes cameras, contact sensors, and a new video doorbell. Motion detection can trigger lights to flash red, activate Hue's new plug-in chime/siren, and send an alert to your phone with a button to call emergency services. [...] MotionAware is built on RF sensing -- a technology that uses wireless signals to "see" a space and detect disruptions within it. The data is then sent to the Bridge Pro, where AI algorithms are applied to figure out what is causing those disruptions, so the system can act accordingly. This is why it's limited to the Bridge Pro, the V2 bridge isn't powerful enough to run those algorithms, says Yianni.
