Looks like you've got some great pointers to get you started. Just wanted to add that for your lights, you could probably just use Basic Rules. There is nothing "basic" about this app, it has become a powerful if/this/then/that app.
If you can break the rule in basic logic "when this happens, do this, then do some other things," then the Basic Rules is the tool for the job.
Rule 1 When sunset, set the light to 7% then wait and when time is 1 AM turn off.
Rule 2 When motion is active set the light to 100% then wait until motion stops and stays inactive for 3 min, then set the light to 7% (with time restriction). Your rule would look like this:
Rule 3 is a repeat of rule 2 but with different restriction.
