I programmed my keypads to light up a function key of the garage door is open. But the wife always wants the MBR keypad to not be illuminated because it keeps her awake at night or something. So I can only see if the garage door is open in the MBR if I press a key on the keypad to illuminate it. If I could set something up via an output that just uses a small LED to indicate status, rather than the HUGE brightly lit keypad, I think the wife would go for that.
I'm planning to do something similar with my OmniPro. I'm going to use an HAI house status switch, and have it light up a button on the switch if a door is open. Pressing that button will send commands to close open doors, and then poll the status after a suitable wait.
