I've mostly lurked here for the last few years, but with a new home nearing completion questions will be coming soon.
While I may delve in to some more advanced HA at some point, we're primarily interested in lighting control for the new home. Every room in the house can benefit from scenes, and some entry/exit paths could benefit from multiple circuit control as well as "all off."
Based on feedback here and elsewhere we're going with SA UPB. Had the electrician wire things up accordingly, but I should have done a bit more homework...we've several areas where a bank of UPB switches will go, but also wired in an extra single gang box nearby thinking we'd want separate scene controllers from the bank of switches. In retrospect, we probably could have eliminated all the scene controllers and simply used US2's - but the function of those didn't sink in until just now, and I'm ready to start ordering and hooking things up.
Thanks to all who have shared here - it's a great resource.
