Thanks for the input. I contacted the Lutron Customer Service through email with a floor plan and some of my thoughts. They forwarded me to a local rep but I got a voicemail. I'm not sure how much they'll help though because their site looks like they do a lot of commercial jobs rather than HT/HA work.
For what it's worth here's the floor plan with my added notes:
* The large central room with the green labels is our entertaining/home theater area. That zone has no dedicated lighting nor switches so currently we have 3 lamps that we manually turn on and off.
* The red labels are the fixed lighting for the kitchen area, and this is the only zone that has switches for the lights, other than the bedrooms.
After what you guys have said, my roommate and I have considered two Lutron Maestro's (one for the red zone, one for the green zone), we have also heard about the Lutron Spacer, and we have looked a little at the Phillips and Insteon bulbs as well. If we can incorporate the two bedrooms for little additional cost then that is a plus as well, but not a requirement.
With the Maestro, how do I separate zones (what is the brain of that system)? Can we just buy individual lamp dimmers
for the green zone? Or do we need some other a la cart
grouping of components?
TLDR - The goal is to have at least two separate zones (red and green) but we are unsure what hardware is needed to facilitate that. We'd like to program the Harmony 890 for both zones, but if they also include pico remotes and/or wall dimmers/switches then so be it.
