eltin,
I'm not really sure it is possible to get switch status or send ON only command. There is a small chance of that, beause of "scenes" feature of advanced remote control.
As far as I remember (I've lost manual), there is a way to record several "scenes" with remote. Each scene means that one button can turn on several switches simultaneously. The thing is that required switches must be turned on prior to programing a scene. So I guess remote somehow "knows" which switches are on.
Again, I'm not sure it is working that way. I'll get back to this a bit later, sorry.
