Thanks neslekkim, I did find that source code when I was looking into this late last week.
I'm a bit concerned that the Relay module might not be supported going forward (GoBus 1.5+). I bought the Go and the Relay a while ago and have been looking forward to the upcoming Ethernet & Temp/Humidity modules so that I could work on a home automation project (controlling gable fans based on temp & humidity).
Are there plans for updated Relay modules that will work on the Go in conjunction with the Ethernet and Temp/Humidity modules?
Thanks!
