You can use MT just fine without trakt, trakt is just an addition, right… So once you’ve imported your movies and series it will keep track of episodes and such. I started using mediatracker not too long ago. In the beginning just for testing because i was in the same boat as you, i wanted something that i could implement in HA for movies, series and games. For now i have just added stuff manually, I haven’t really looked into all the features because I spent time integrating mediatracker calendar component and card, as well as a python api wrapper.
I haven’t bothered with scrobbling in MT but of course that’s a nice feature. I am not actively on trakt but use it more for scrobbling from jellyfin, and locally I’m running something called jellyseerr.
I recently got my rasberry pi and set up home assistant for the first time.
Tracking books and other media is a feature I definitely want for my home.
Is there a best practice for integrating other services? I.e. MediaTracker can be installed as a npm package as well as a docker image. Are there any pros/cons for one way or the other? Which method was your choice and why?
