Hey all, What is the best way to setup a program(s) to have my ISY99 and I/O Linc (with sensor) let me be notified when the door is in the "off" state for more than 5 mins? I figure monitor for the change in state and in the "then" section do a wait 5 mins, but then what? Sorry very new to ISY programming. Thanks in advance, j
