No, it takes care of itself. If both doors are open, the group is true. If either door is open, the group is true. If both doors are closed, then and only then can the group go false.
Might look something like this:
- Root group - AND or NUL operator
- Group “Any Door Open” – OR operator
- Device state, door #1 open (e.g. door sensor device Tripped variable
is TRUE) - Device state, door #2 open
- Device state, door #1 open (e.g. door sensor device Tripped variable
- Group “AC Control” – AND operator
- Group state condition, current ReactorSensor, group “Any Door Open” + options “sustained for” 30 seconds and “delay reset” 30 seconds (set the delays to your sensibilities–these are examples).
- Group “Any Door Open” – OR operator
Activities:
- “AC Control is TRUE” - device action to turn off the AC unit
- “AC Control is FALSE” - device action to turn on the AC unit
The use of the “sustained for” delay on the group state condition allows a door to opened briefly without turning off the AC (just passing through). Likewise, the use of “delay reset” means the doors have to stay closed to allow the AC to be turned back on. This dampens the switching action a little and prevents banging your AC on and off in time with the swing of the door (which may short-cycle compressors, etc).
You may need to use the variable/expression tricks in this video to save and restore the operating mode of the AC unit if you are doing it by controlling a multi-mode thermostat. But if it’s a simple on/off control or a thermostat only switching between OFF and COOL then you don’t need to do that, just set the state/mode of the AC control directly.
