We do loads of Home w 2n and far and away the most efficient way to go about it is the LCUK module, works great using quick actions to control any 2n switch, full feedback, no need for DTMF stuff. 

 

Of course, if not 2n, or your required DTMF tones change, that's a whole other challenge... I don't believe DTMF control is exposed in CH and likely won't be anytime soon.
