Wireless dimming for four groups of lights. Battery operated (3V) remote has a holder, that can be mounted on a wall (remote will stay on the holder with magnet). With your remote, you need receivers to all groups you want to control (max. 4 groups). You can pair multiple receivers under one button.
To turn ALL groups ON and OFF, use the buttons on top.
To adjust the brightness of a certain group of lights, use the buttons of that group. TO brighten, press ON for long, to dim press OFF for long. Short press turns the light ON (when pressing ON) and pressing OFF fast, turns the lights off.
So for example if you have led strip on the top and on the bottom of kitchen cabinets as well as led spots on the ceiling, you could have three "groups" (all with their own receiver). One receiver for top cabinet lights, one for bottom of the cabinet lights and one for spots on the ceiling. Then just pair the desired receiver with a number on the remote.
