Just to update anyone following. .
RadioRa2 is a 'supported' trigger for the MLGW.
You have to use the 'custom strings' section, but it's very doable.
It requires writing some trigger/inputs for RS232, very simple with the Lutron integration protocol info.
I now have a 6 button keypad where 1 button controls a light, one the "CD" function (for a BS9k linked), a "radio" button, an "advance" button (for filtering through songs/stations, and "standby"
The raise/lower buttons are usually used for dimming but I have programmed them to control volume up and down.
This is very exciting news. . .I will report that the MLGW will also tell the RA2 system what to do with no problem as well. I.E. my "cinema" button the BEO5 sends commands to my Lutron system through the MLGW (over ML) to turn off kitchen lights, turn on bar, etc.
VERY VERY COOL when you get your head wrapped around it.
This is a very nice way to have home automation without the need for a crestron/savant system. . the BEO4/5 can be your whole home remote as long as there is a B&O product to send the command over ML
Wanted to share.
I'm ready for something new that I actually want to buy!
