You can control your lighting even more easily & flexibly without even having to press a switch with the battery-operated SMART+ motion sensor. The sensor senses movement within a 100° radius & at a distance of up to 4.5 metres. & it checks to see if you are still there, only switching off when you leave the room. The motion sensor is the ideal addition to your smart home system as it even shows you the current room temperature in the app at all times. You can programme up to four different lighting cycles in the app. So small & yet so smart: as it is so compact, it can be instaled in the narrowest corners.
