I have used x10 for many years. I recently acquired a Sony Tablet S which has an ir blaster. It also has a Sony remote control app which can also learn ir commands.

I thought that one of the things for which I could use the tablet would be as a replacement for my old Pronto. The tablet very easily learnt the commands from the Pronto - all except on and off. So no problem with bright,dim, A5, C12, etc. Each time (I have repeated this many times) the tablet would say it has learnt the codes but each time I play back on or off my IR543AH doesn't blink. The original Pronto commands on and off work fine.

I can turn on a lamp by giving a bright command but that won't work for macros or for turning something off.

Anyone have any ideas as to why?
