Node-red get entity parent / group

Third party integrations Node-RED

How can I get an entity ‘parent’ or ‘group’ in node-red.

Example. I’ve a ‘states node’ with regex _adjust$ that captures a lot of entities. Next step I would like to lookup what ‘group’ it’s attached to (e.g. livingroom, bedroom).

Looking at the data there’s something called parent_id. Can I set that value somehow in HA?
