I've used the RTI keypads to control UPB lighting in a HAI system which worked perfectly. It's a good system if you are looking to do whole house automation (lighting HVAC and some models even have security and CCTV) but the panels allow you to make up your own RS-232 commands that can do anything from turn one light off, to setting temperatures, arming the alram and throwing relays to close your garage doors with one button press. It's a fraction of the cost of a crestron automation system and can do the same things for automation. Your just need a RP6 and CM-232 module.
