Here's an interesting one. I installed a 6 button KeypadLinc and a SwitchLinc, both installed in the kitchen in a 3 way switch substitute.
I have 2 scenes:
"Kitchen Switch - Ctrlr" which contains
1. Kitchen Switchlinc as a Controller
2. KeypadLinc as a responder. This actually turns the lights on.
When I press the SwitchLinc it tells the KeypadLinc to turn on the lights.
I also have another scene "Kitchen Switch - Resp" which contains
1. Kitchen SwitchLinc as a responder
2. KeypadLinc as a controller.
The idea is that the SwitchLinc LED follows the state of the KeypadLinc LED.
On MLHD if I try to turn on "Kitchen Switch - Ctrlr" it gives me an error saying ISY failed to process the request. "Kitchen Switch - Resp" works fine. I think that "Kitchen Switch - Ctrlr" is supposed to be illegal since you're not supposed to be able to propagate controllers.
Funny thing is if I do the same on the ISY both scenes work fine.
