Fork of dersimn's chromecast-mqtt-smarthome-connector, but with some configuration tweaks.
Control behaviour by defining ENV variables MQTT_HOST, MQTT_PORT, MQTT_USER, MQTT_PASSWORD, MQTT_CAFILE.
git clone
pip3 install -r requirements.txt
MQTT_HOST=10.1.1.50 python3 connector.py
Set the log level with the LOG_LEVEL environment variable (possible values).
All environment variables may also be set with a _FILE suffix to support Docker secrets in Swarm mode.
docker run -d --net=host -e "MQTT_HOST=10.1.1.100" nielsrowinbik/chromecast-mqtt-smarthome-connector
Using MQTT you can find the following topics. FRIENDLY_NAME is the name used to connect
to each Chromecast.
chromecast/maintenance/_bridge/online -> bool
chromecast/maintenance/FRIENDLY_NAME/online -> bool
chromecast/maintenance/FRIENDLY_NAME/connection_status -> string
chromecast/maintenance/FRIENDLY_NAME/cast_type -> string
chromecast/status/FRIENDLY_NAME/current_app -> string
chromecast/status/FRIENDLY_NAME/volume -> JSON
chromecast/set /FRIENDLY_NAME/volume -> float
chromecast/set /FRIENDLY_NAME/volume/muted -> bool
chromecast/status/FRIENDLY_NAME/player -> JSON
chromecast/set /FRIENDLY_NAME/player -> string
chromecast/set /FRIENDLY_NAME/player/position -> int
chromecast/status/FRIENDLY_NAME/media -> JSON
Change volume using values from 0 to 1.0:
- Publish e.g.
1.0tochromecast/set/FRIENDLY_NAME/volume
Change mute state: publish false or true to chromecast/set/FRIENDLY_NAME/volume/muted.
Play something: Publish a json array with two elements (content url and content type) to
chromecast/set/FRIENDLY_NAME/player, e.g. ["http://your.stream.url.here", "audio/mpeg"].
You can also just 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.
For other player controls, simply publish e.g. RESUME, PAUSE, STOP, SKIP or REWIND to
chromecast/set/FRIENDLY_NAME/player. Attention: This is case-sensitive!
