Let's go with the event bits as you have them here, but file a follow-up issue to do something better. We really can't depend on real devices not having random other events going on...

Approving so this is not blocked on me, but:

1. Please make sure the problem about expressed state is reflected in the test plan issue.
2. Please fix the backwards PICS for the WaitForMs.

Generally, test plan step numbers in the YAML would help with following these!
