What's Required - A 'Philips Hue Bridge' (sold separately) is required for smart control. Simply connect your new Philips Hue Motion Sensor to the bridge and take advantage of smart home lighting via the 'Philips Hue' app The Hue Motion sensor's integrated daylight sensor detects when there is still enough daylight so that lights do not turn on until you need them. If it's still too dark, adjust the light sensitivity of the sensor in the Philips Hue app to personalise when you'd like the motion sensor to activate. With the Hue motion sensor, you can customise the lights that come on and their intensity depending on the time of day. During the evening, set the motion sensor to trigger gentle night lights to guide you in the dark. During the day, trigger crisp white light to flood your halls. Position Anywhere - The indoor sensor is battery operated, and communicates wirelessly to your bridge, so you can take it wherever you want to detect movement. All the necessary components are included to mount it on the wall or in a corner Trigger your smart lights with movement. The battery-powered Hue motion sensor can be easily installed anywhere in your home.
