My house has several keypad links in my ISY Automation system. On most keypads all the buttons correspond to different scenes in a room. How in the ISY 99i do I program a keypad so that if it is on Scene B (For instance) and a user presses Scene C then the light for Scene B will turn off (because now the room is in Scene C and not Scene ? On another topic... I have my ISY 99i system programmed so the X10 motion detectors in rooms of the home turn on certain scenes for a room based on the time of day. At night I have a dim scene (Scene A) turn on in the master bedroom. But what if my wife is reading or packing and needs more light? She walks to the keypad link and presses Scene B and the lights brighten. But once she walks back over to the chair she trips the motion detector and the lights return to the dim Scene A. My question is how can I program the system so that when a user manually presses a scene on a room's keypad link it will override the motion scene that would otherwise occur based on the time of day. Once the override is enabled I would then program it to turn off the lights in that room if motion is not detected for an hour Any help is appreciated, Thanks
