Summary

New Version: http://www.kratzer.it/lichtschalter.html (sorry only german)

Smarthome mqtt switch. With 4 touch buttons and one or two rgb LEDS.

This to covers are for Busch/Jäger standard program. But you can print your customized covers for your switch system. I think it works only with German/EU switch programs.

The switch can be used as a original mechanical switch replacement. But it has 4 button and only one 220V 5A power switch. In my case the Button1 is Alarm and switch on the lights around my house. Button2 switch on the main room light over the power switch. Button 3 switch on an indirect light (white) and Button 4 enable my rgb light.
For Button3 and 4 i use this box: http://de.aliexpress.com/item/RGBWW-Strip-WiFi-Controller-1-Port-Control-200-Lights-Communicate-with-Android-Phone-Via-WLAN-to/32502007408.html
