Hmmm, have you seen the Circuit Cellar Home Control System? Those who
used to read Ciarcia's Circuit Cellar in Byte will know that he
started his own mag called Circuit Cellar Ink.

They have developed a new home control system, which is based around
a multidrop RS485 network. You might like to check this out and see if
anything to do with the project is applicable to what you're trying to
do.
