Is it possible to control Lutron RadioRA 2 lights with a URC TRC-780?

2-Way, most likely not.

Yes, it is.

TRCGroup:
I am comtemplating doing exactly this. I'd like to control the lighting system of my RadioRa2 main repeater via a TRC-780.

How are you able to do this? Via RS232 (serial), or IP commands via HTTP Get/Post?

Can you provide a simple example?

Thanks.

I control my RA2 system with 1-way RS-232 output from a MSC-400 to the main repeater. The codes are in CCP which are basically press and release codes.

You just need to create phantom buttons in RA2 in the main repeater. These can be simple button presses that control 1 zone or scenes that control multiple zones.

Then create a lighting page and buttons in CCP and drag the RS-232 codes onto the buttons that match the RA2 phantom buttons you created.

The phantom buttons can also be used in macros as well.

Any activity I press for my projector, closes the RA2 blinds and sets the lighting to match the activity!

Lutron RA2 is a great product!
