Thank you, that is helpful. Unfortunately the API documentation is lacking 
quite a bit of detail re CMD_READ_RAIN (0x57) so coming up with reliable

I'm not surprised. I'm seeing more fundamental problems where the GW2000 
does not respond to CMD_BROADCAST when connected via wifi but does respond 
when connected via ethernet.
