This app is able to turn on TV through hdmi-cec, find the TV and stream the music using Google Cast protocol. App provides endpoints to
- turn on tv
http://localhost:3000/on
- turn off tv
http://localhost:3000/off
- check tv status (standby/on)
http://localhost:3000/status
- schedule turning off
http://localhost:3000/scheduled-off/{minutes}
i.e http://localhost:3000/scheduled-off/45 will turn off tv after 45 minutes
- cancel scheduled turning off
http://localhost:3000/schedule-cancel
- play random Spotify playlist using Google Cast protocol It turns on the TV, starts streaming a playlist from predefined, hardcoded set, and turns on the shuffle mode
http://localhost:3000/spotify-start
- play specified Spotify playlist using Google Cast protocol Like above but you can specify playlist uri with the url path
http://localhost:3000/spotify-start/{spotify-playlist-uri}
