I use Real Debrid with Stremio + Torrentio. I just need to figure out how to add the manual torrent search & download plugin for Real Debrid since I watch a lot of obscure British TV, not everything is hosted already.
If you mean caching content to RD I think you can do this with the Unchained app, if you use Android, or you can do it pretty much anywhere you like using the RD website.
Then you can use the DMM addon to watch it on Stremio, or probably it will show up with any addon that supports RD, or if not then you can simply use the Debrid manager that is available at Torrentio, or as a standalone addon.
