Topic per title, basically.
For me: after setting up all the integrations and fall overs using the arr stack and Jellyfin (inc Sabnzdb etc)… I keep circling back to Nova video player.

It’s arguably not even self hosting…but there something undeniably cool about sticking a USB stick into a router, installing a single app on your TV and boom, done. EDIT: of course, it can consume the *arr stack, integrate with Ombi etc
IOW, I really like stuff that simple to set up and punches above its weight class.
Maybe use ESPHome on to run the servo back and forth a few times and have an automation in Home Assistant to trigger the servo when it detects the toilet running. The hard part would probably be getting power near the toilet and connecting the servo to the handle in some fashion.
