Dear all. We have built a circuit, named Titino, that allow to program Arduino by using RS485 network. Titino allows at Arduino to use his RS485 driver to realize a powerful network.
If you mount Titino over an Arduino Pro Mini (Titino have the same dimensions) you will have RS485 node useful for realize a (cheap) building automation applications.
I hope this circuit is interesting for you.
Titino will be at Maker Fair Rome 2014.
