I have two spotlights which I want to control together. They are not on the same relay so I can't use logic on the channels. I would also like to avoid having to use two buttons on the light switch to have Scene On and Off (or use one button for each light). Would an alternative be to use logic in a PAC so that whenever one of the lights is turned on, the other turns on and when one goes off, then other goes off? Is there any alternative?
