fastbird1 Posted January 19, 2015 Posted January 19, 2015 I purchased 6 of the 2GIG CT100 thermostats and a new ISY994I-Z. I also purchased a bunch of the door contacts and motion sensors. I have them all connected and can see them in the ISY. But I did not think this through. Goal: Shut off thermostat A/C when door is left open for longer than 10 minutes. That part was easy. But I want to turn it back on ONLY if it was off because the program shut it off. How do I know if the program shut if off, or if it was never on? Second question: I want to roll back the temperature after a period of time of no activity and door is closed (during day) - If motion is sensed or door is open and ONLY if the thermostat has been setback - I want to get it back to where it was. I am way over my head. Its a vacation rental in a hot area. Any help would be greatly appreciated.

Another program can detect the door closing and if the first program is running. A variable could also be used as a condition flag to tell if your ISY program did it. I use a series of programs to detect I am home. Every motion detector triggers a program that calls a retriggerable timer set for about 4 hours. If it times out then I am not home. Special consideration is used for expected sleep times so the timer will stay as put while I am sleeping. Special consideration is used when my usual exit door MS detects motion there, allowing only 20 minutes to cause the Home flag to reset..

fastbird1 Posted January 19, 2015 Author Posted January 19, 2015 Is there an example of how to store the temperature setpoint so that i can restore it when motion is detected?
stusviews Posted January 19, 2015 Posted January 19, 2015 Thermostat setpoints don't change unless you do something to change it. Do you mean to restore the setpoint if someone changes it?
larryllix Posted January 19, 2015 Posted January 19, 2015 Is there an example of how to store the temperature setpoint so that i can restore it when motion is detected? No. Possibly coming in ISY V5. You can run a series of temperature comparisons through the range of expected temperatures (successive approximation via value trial and error) and store the results in a variable. Now you can't store the setpoint saved in the variable back into the thermostat though. It would be much easier to set up a few programs with preset thermostat values and then call them under desired trigger conditions to get your preset setpoints. If condition A is on Then set thermostat this way Else Run Program stat2 (if) Program stat2 -------------------- If Condition B is ON Then set thermostat that way Else run program stat3 (if) Program stat3 ------------------- If --- Then set thermostat the other way Else --
