After considerable planning and many forum posts that you guys have helpfully answered I've completed my (mostly) whole-house Caseta installation. Attached are a few pictures showing the results. I believe that I used every Caseta device in my installation (SBP, dimmers, PRO dimmer, PRO switch, lamp dimmer, 2 & 3 button Picos, and even the 4-button scene Pico). I also mixed in some Maestro devices where I didn't need automation control (e.g. powder room) or needed more control than Caseta offers (e.g. motion sensor, timed switches for bathroom exhaust fans, etc). In total I replaced 40 switches so I'll be bumping up against that 50 device limit pretty soon once I start adding shades, thermostats, and more Picos. Hint, hint Lutron!
The planning probably took as much or more time than the actual installation. I have a bunch of mult-gang boxes so that made installation a little more difficult. So far I'm loving the system. I've had a few minor issues on the app side of things, but the system hardware has been rock solid. I get a wireless range of 50' without any problems.
