Hi All,
I posted the demo sketch for reading Insteon commands to the wiki:
It waits till it receives an insteon command via the serial modem, and then reports it via serial. While it seems to work well on my home setup, it would be great to confirm it functions for others as well.
In addition, I've added some better diagrams to the home automation shield page:
One diagram labels the different parts of the board to help clarify the functions/features. The other diagram at the bottom illustrates which pins do what.
Enjoy!
Alan
