 Each accessory have a unique deviceId that is transmitted during the learning process, 
 the emitterId bounds a switch to that emitter, a switch can have multiple emitter associated (a remote control).
 
+Options :
+
+* dimmable : register the switch as dimmable lightbulb
+* invert : invert the state of switch (turn on -> off, turn off -> on), this configuration is used in case of electric heater setup (see: http://www.planete-domotique.com/blog/2012/01/05/piloter-un-radiateur-grace-a-son-fil-pilote/)
+
 ### Learning process
 The learning process is actually the same as described in the guide of the switch seller. A 'on' code has to be sent to the switch
 during the learning process initialization.
