How do I automate based on the trigger of another device?

[parautenbach (Pieter Rautenbach)]

Work with "Triggered by" in automations

Based on my own testing, this is combination of values that characterize each action: Action id parent_id user_id Physical Not Null Null Null Automation Not Null Not Null Null UI Not Null Null Not Null A more comprehensive list of actions can be found here. If you are saying that your testing shows that Physical and UI produce identical combinations then, unfortunately for you, there’s no available means of distinguishing between the two.

And many more posts already on this topic.

Rather use the event listener under the dev tools to see all event data.
