Hello Mark,
Well done ! I used your codes and they worked. How did you create them ?
For my X10, I have a RadioShack 15-1919R (part of a remote control setup. (the remote for it broke, an I was using a newer RS 15-1995). I was able to teach the neo from this remote, but never got the neo to work on the x10.
I even have a (big)pronto TSU2000. Was able to teach it the x10 commands from the RS1995, and it worked ok.
I even did copy and paste the codes from the bigpronto to the neo (in neohacker) but they didn't work.

Please let me know if I can assist with testing the other codes, or how you were able to create them.
Need units 1,2,4 allon alloff bright and dim.

Thanks
Steve
