HI
@Mrjoel86
The sphere system has 6 inputs, how many inputs do you need? I actually separated some of the lights in my caravan and bought a new 4 way transmitter with master off to control the lights. My caravan already has a 2 gang switch for the outside lights, so I am now using all 6 inputs. It was quite easy to reprogram and I am happy with the additional flexibility to control the lights. If you need more than 6 inputs, I can't see why you can't add another receiver module.
Cheers
Nick
