Hi Adam - thanks for the kind words. This particular thread is about multi-device actions, so most presence sensors don’t have commands (actions), but if you were using a Virtual Presence sensor for example, yes, this could be used with those as well.
As to the question on Triggers, be sure to check out the sister thread for Multi-Device Triggers and Conditions - the short version is that Triggers are always OR’ed together and with Conditions you can adjust the containing condition between AND/OR and the inner Multi-Device Condition will match that.
To accomplish something that only executes when both devices are in a certain condition, you would add the devices to both the Triggers and Conditions and make sure the condition is set to ‘all’ (AND).
Triggers:
- If any of Presence1, Presence2 changes to ‘present’
Flow:
- If all of Presence1, Presence2 is ‘present’
- Then Do X
- Else Do Y
