ZigBee remote with 4 pushbuttons (battery powered)
For example, the 2 left buttons can switch the light on and off with a short press and dim up and down with a long press. The 2 right buttons can then be assigned individual light scenes and color moods.
The pushbutton has an absolutely flat design and can be simply glued to the wall, for example. The button is powered by a 3V coin cell with several years runtime.
