RL, Thanks for your reply. Was planning on the Serial Port Expander as
needed that for my UPB lighting already in place. Didn't realize I
would have to wrte rules though. All indicators from the help I
recieved on this board point to going with thermostats and biting the
bullet on the ELK touch$creen if I want a fancy interface without
relying on a PC.

I will take a close look at the RCS thermostats you recommended.

Thanks again, Ray
