The relay board you are asking about has good documentation on the webpage and also a C# example. The webpage shows examples using http commands , so it should be easy to do this with HomeGenie:
192.168.0.200/io.cgi?DOA2=10
This would use the default address (192.168.0.200) and make output 2 active for 1 second.
Another example would be to set output 1 inactive for 10 seconds:
192.168.0.200/io.cgi?DOI1=10
So in HomeGenie something like:
Net.WebService("192.168.0.200/io.cgi?DOA2=10")
How do you guys safely use these high voltage AC relays? I'm fine tinkering around with 5V, but I don't know about using 120VAC without a UL approved enclosure. Are there any cheap UL approved/enclosed 120VAC relays/switches that could be controlled via a low voltage output signal arduino/rpi?
