Plug In's

Not sure where to ask this so figured I'd put it here.   Two questions:
1) I see a lot of talk about HomeAssistant in the forums but no mention of it elsewhere (that I could find).   I take it MyServer integrates with HomeAssistant?   Or vice-versa?
2) Is there a Plex plugin/driver?

Thanks! Chris

Yes, there is a gateway driver. More info in the respective area here on the forum.
