This is very interesting to me. I have a fan that I have been trying to control (through all learned commands) and I get very similar behavior.)

So, if I'm understanding this correctly, every button has an "A" and a "B" command that it sends, and you only want to learn the "A" commands. But then in the Nevo, each button push needs to send the appropriate "A" command followed by a null "B" command. Am I getting that straight? I don't really get what the "B" commands are even for. Also, what do you mean when you say the Nevos have an A/B feature?

Sorry for all the questions, but I'd love to understand this to be able to deal with it whenever it arises. In the case of my fan, some buttons are toggles, for example, the SPEED button cycles the fan between low, medium, and high speeds. Does that scenario still lend itself to the A + (null)B macro solution?
