Read/Update Temp via RS-232?

[schalliol]

If one has a Lutron HVAC system and wants to use a home automation system with say a music display, security, etc, is there a way to read the current temperature so the automation display can display this as well?

You can ask the RA2 system for its current temperature by sending ?HVAC,(ID),1. (ID) is the integration ID of the zone that you want to read the temperature of. The response will look like ~HVAC,(ID),1,(TEMP).
