I'm not sure what threads you read, but there are a few that discuss this issue. Rule Machine (assuming that's what you're using) doesn't have a direct way to access the physical vs. digital status of locks/unlocks, perhaps a decision they made due to the fact that not all locks support this (it is supported for switches and dimmers; I guess that is more common).
One workaround for a specific lock is here:
This can likely be adapted, if even needed, to work for other types of locks. That being said, the implementation seems a bit odd to me since an app should be able to just access the physical/digital status, if supplied, directly rather than hunting through the description text for it (which alone might be a workaround without this in RM if your lock consistently reports something that could be used there).
However, you may wish to consider other things people have recommended instead. For example, a physical unlock is highly likely to also trigger motion in the area (by definition, a person should be there doing it). Do you have a motion sensor (or more) that you could use and check as a condition in your rule/app instead (you can still trigger based on the lock)? Or is there another workaround like presence you haven't considered? Explaining your actual desired outcome might give other people ideas to share that you'll also like.
