Good news, folks! Motion sensing triggers will soon be available to further trick out our Philips Hue lighting installations, without complicating matters with yet another hub and ecosystem — like Smartthings. From the FCC submission, we glean the Philips Hue Motion Sensor (with ambient light sensor) is both battery-powered and Zigbee-endowed. While we’d typically expect an accessory like this to be fueled by a watch battery, an overseas retailer Alza indicates a pair of common AAA batteries will be required — conceivably reinforcing what looks to be a 2×2″ profile. Further, the description indicates a 100 degree field of view over 5 meters. And, if we use their pricing as a guide, we should expect the Hue Motion Sensor to land somewhere in the $40-60 range when it hits within the next few weeks.
