While cleaning up the docs and GitHub issues, I found a really old feature request for some way of automating device creation based on the Lutron device database. I started playing around with that today, and I'm actually making good progress. I'm at the point where I can parse the XML data from the repeater, and I'm about to start on creating the devices.
I have a two repeater system, with right around 100 actual Lutron devices (dimmers, switches, shades, keypads, etc). When you count individual buttons on the keypads (8 buttons plus 6 LEDs), that a huge number of devices. I think I'm going to have to group them into folders on creation, or it'll be incredibly hard to find anything. The question is - group by room or by device type? Or an option for either?
