[QUOTE="jonnyy2357, post: 493105, member: 32384"] Update: I got it to work by using 1 of the COM wires, and isolating out the other two. All three COM wires were on the same circuit, and i double-checked using a multimeter and testing pairs to the COM wires on the resistance setting and found all three wires were already connected to each other (i.e. the meter had zero restance between any pairs of the COM). The capacitor method worked nicely too. The blurb is that without the neutral wire, the switch keeps a low amount of current flowing one of the lights to keep the switch itself powered up (otherwise you'd lose the smart connectivity when all the lights are off). The light that's kept on low power will flicker if using low energy bulbs and the capacitor is used to stop the flickering. Once i wired up the switch, i turned it on to see which of the lights flickered before installing the capacitor just to double check which one needed it. Pretty happy all round :) [/QUOTE]
