Hi guys. Have a XP-6 in a splited room. When door sensor is closed I want 2 small rooms and 2 IPads, one for each room with specific menus for each room. When door is open I want one IPad to show a standby menu and the other IPad controlling everything in the big room (I am talking about video, sound and lights already in place). The trick is the door sensor that I want to introduce and limit 1 or 2 IPads for controlling the space. Any advise. TIA
