I want to build a alarm system with multiple states and actions depending on what caused the alarm. First some Setup Information I’m running openHAB 2.3.0 on a local Debian 9 Server (x64, 8GB RAM). My Smarthome componeds are mostly Homematic and I use the CCU2 as bridge with the homematic bindin…

You may want to check out triggering items, here is an example: rule "Member pressed" when Item group_1 received command or Item group_2 received command then logInfo("GroupTest", "Member " + triggeringItem.name + " to " + triggeringItem.state) end

You might find member of myGroup rule triggering helpful, as it allows identification of the triggering Item. [image] Features for Rules that work with Groups Tutorials & Examples Introduction This post provides an overview of two features that have been added…

Looks like Member of goes into the right direction. But one problem left. How do I ignore windows that where already open at the moment of arming?

I think using ‘changed from … to …’ in the trigger should work: when Member of MyGroup changed from CLOSED to OPEN then ... This won’t trigger if a window is already open and receives an OPEN update.

You can use an if condition in the rule that checks armed.state == ON as an example. If its off then the rule won’t continue.

from CLOSED to OPEN is not safe, because the wind could close the window and reopen it.

If you want to account for that possibility, the only way I can think of is to have a rule that triggers when the security system is armed which populates a “triggering group” with only the windows which are closed at that time. This triggering group is then used in the trigger of the main rule. Som…

That sounds good, I will test that. Update: Seems to work so far :slight_smile:
