You definitely can mix the two, and we actually find it a very useful thing so you can have your metadata available to query alongside the time series data. TimescaleDB will only make a table a hypertable if you tell it too, otherwise regular tables should work as you'd expect. And since we appear as a table in the contexts that it matters (JOINs, querying, inserting, etc), you shouldn't have any issues mixing the two.
