Maybe so, but they don't provide homeowner access to their website to download the RA2 software. I designed and installed an original RA system in a 1700 SQ FT townhouse and programmed it manually. Even used the klugey RS-232 to Ethernet interface to link to a computer and control via 3rd party software.
But my RA2 system has too many dimmers, switches, and keypads to try to program manually, even though I've laid out all of the scene and zone logic myself. If my installer hadn't left me with a copy of the software, I would have no way to get it (or to your point, I'm just not smart enough). There is no way that I can see for an average homeowner to do this as a DIY without the aid of someone who is licensed to get access to the software. And an authorized installer isn't just going to give you the software for nothing.
