A light in the Mudroom is turned on, and an event should propagate up so that the Main Floor and Home would switch to an “occupied” state. That way, any event in any part of the home will keep the Home in an occupied state.

• Design Pattern: Sensor Aggregation

@mjcumming

The problem in this scenario, is turning on that inside light will change the status of the home from vacant to occupied. So we then need a way to “lock” that state of the home while turning on that light so there is no change in occupancy.

• Design Pattern: Manual Trigger Detection

If it is night and the light was turned on by a Rule you know not to change the occupancy switch for that room.

@mjcumming

Another scenario, say the security system is armed “AWAY”. In this instance, the Home would be set to vacant, this event would propagate to all the different rooms, and appropriate actions would be taken ie turn off lights, music, change temp etc.

Just send an OFF command to the Group that contains all the Items that indicate occupancy.

You will probably want to draw out a state diagram to make sure you don’t have any incompatible state transitions. You can easily end up in a situation where a state transition event changes and you end up in two incompatible states.

For a setup this complex you will probably want to use a bunch of proxy items so you have some control over how the events propigate.
