While I am waay not the expert on this, you do not need to populate the Ruby codes. Just select the Insteon template and do a quick reload.
I believe it will start to locate your Insteon devices by itself, but if it doesn't, just put add an Insteon device and watch it go.
As far as it being beta, my guess is yes since it seems to be a bit touch and go. (I have lots of difficulty. After all, I am over 40!).
