I'll give you my experience after 10 minutes with taste.
I have a wireless operator as it also occurs in radio-controlled sockets. 8 buttons. At 4 and 4 for disable. The lamp is a quick learner, but can be then by all 8 buttons turn on the lamp. Turn is relative, because I have not figured out how to wirelessly and not over the light switch off .. matter.
Once button on remote control = lamp in version dims once down completely and then right back on maximum high. In order to obtain a brightness now again press button on the remote control and the dimming process is therefore stopped with current brightness. Pressed back button and the game continues.
For me as absolutely useful, because I just wanted to dim every time without having to fiddle around on the ceiling above. Light switch is used for maintenance as previously also to fully or off.
