Thanks for the detailed info Nick, I did manage to get 22 lights working last night before you had made this reply and fell asleep before mentioning I got that part solved. I can confirm a few different EX brand switches work without a problem.
I have the following working and they all seem snappy and work fine.
2 - CLW-DELVEX-P
14 - CLW-DIMEX-P
6- CLW-SWEX-P
After I got them into HA I started testing Alexa with the Nabu Casa service and while it does work it seems if I manually turn off a switch and then try to turn off using my Alexa command it doesn’t work, anymore, though your component continues to work perfectly which is a good thing.
This weekend I’ll maybe add a thermostat and some temp sensors and I also have two fan controllers I’ll add to my pages so the wife can have access to low/med/high controls.
I’m like the car mechanic who drives a broken car but in Crestron land, it seems I am fixing everybodies crap and neglected my home system for years because I was too busy.
No worries about time Nick, a person can do lots with this component right now, I’ll be trying to figure out more soon because I’m still somewhat a newb to Hass, maybe a year and to be honest I never really delved into scripts and templates, that’s next 
Thanks again!
