I currently have 8 x10 items I control then with my pronto using an ir543. This has been set up for about a month. so far no problem until now. I can't get one of the wall switchs to work. It just stopped responding to pronto everthing else works fine. It works fine with my powerhouse remote. But it does not work from the key pad on top of my ir543. Any body have any ideas why it stopped working.

sometimes this is known to happen have u checked the wiring sometimes these products do go bad

thanks, It's now working again, I don't know why i didn't do anything. But before it started to work again I changed the code to another number. It still did not work so I think it sounds like the switch went bad. I just order a few new ones. If this happens again I will change the sitch. Thank you for the advice
