# Chromecast MQTT connector Provides status information and control capabilities of your Chromecast devices via MQTT. ## Installation requirements * Python 3.7+ * pychromecast * paho-mqtt You can install the requirements in their correct versions using `pip3 install -r requirements.txt`. ## Discovery and control Using MQTT you can find the following topics. `friendly_name` is the name used to connect to each Chromecast. ``` # - read only chromecast/friendly_name/friendly_name chromecast/friendly_name/model_name chromecast/friendly_name/address chromecast/friendly_name/connection_status chromecast/friendly_name/cast_type chromecast/friendly_name/current_app chromecast/friendly_name/player_duration chromecast/friendly_name/player_position chromecast/friendly_name/player_state chromecast/friendly_name/volume_level chromecast/friendly_name/volume_muted chromecast/friendly_name/media/title chromecast/friendly_name/media/album_name chromecast/friendly_name/media/artist chromecast/friendly_name/media/album_artist chromecast/friendly_name/media/track chromecast/friendly_name/media/images chromecast/friendly_name/media/content_type chromecast/friendly_name/media/content_url # - writable chromecast/friendly_name/command/volume_level chromecast/friendly_name/command/volume_muted chromecast/friendly_name/command/player_position chromecast/friendly_name/command/player_state ``` Control the player by publishing values to the four topics above. Change volume using values from `0` to `100`: * Absolute: publish e.g. `55` to `chromecast/friendly_name/command/volume_level` * Relative: publish e.g. `+5` or `-5` to `chromecast/friendly_name/command/volume_level` Change mute state: publish `0` or `1` to `chromecast/friendly_name/command/volume_muted`. Play something: Publish a URL to `player_state` (just as string, not as json array, e.g. `http://your.stream.url.here`), the application then tries to guess the required MIME type. Or you can publish a json array with two elements (content url and content type) to `chromecast/friendly_name/command/player_state`, e.g. `["http://your.stream.url.here", "audio/mpeg"]`. Or you can publish a json object with any of the following properties, e.g. `{"url": "http://http://your.stream.url.here", "content_type": "audio/mpeg", "enqueue": false}`. Known properties from pychromecast BaseMediaPlayer.play_media() function: ``` "url": "http://http://your.stream.url.here" "content_type": "audio/mpeg" "title": null "thumb": null "current_time": null "autoplay": true "stream_type": "BUFFERED" "metadata": null "subtitles": null "subtitles_lang": "en-US" "subtitles_mime": "text/vtt" "subtitle_id": 1 "enqueue": false ``` For other player controls, simply publish e.g. `RESUME`, `PAUSE`, `STOP`, `SKIP`, `REWIND`, `PREV` or `NEXT` to `chromecast/friendly_name/command/player_state`. Attention: This is case-sensitive!
