This is a consideration for me, since I'm in the middle of a pretty big upgrade to smart switches throughout my basement and main floor. I think this will be very appealing for the right potential buyer. I'm just curious what I'll need to do to make this a feature. Maybe de-sync it from my system and provide a Smart Things hub and get them all set up with it there so it's easy.
I'm not getting rid of the existing switches and plate covers, so at least I can more easily remediate it if the future buyers don't want the system.
