chromecast

name	chromecast
description	Control LG TV and Chromecast via natural language. Triggers: tv on/off, music, yt/stremio [query], app names (netflix, plex, etc.), pause/resume/mute, volume.

Chromecast

Control the Chromecast via go-chromecast.

Run all commands via the Bash tool. Report results concisely.

The skill loader provides the base directory above. Set this before running any scripts:

SCRIPTS="<base directory>/scripts"

go-chromecast: always pass --addr flag - without it, go-chromecast prompts interactively and loops with EOF errors in a non-TTY shell. Always source config.sh and use $CHROMECAST_ADDR:

source $SCRIPTS/config.sh && go-chromecast $CHROMECAST_ADDR <command>

Volume/mute: always use lgtv - go-chromecast and ADB volume/mute commands silently fail.

App launching: always use launch-app.sh - wraps ADB monkey with focus confirmation.

---

Shorthand triggers

All triggers require the tv prefix (e.g. "tv next", "tv pause", "tv yt query").

"tv on"

$SCRIPTS/wake-if-needed.sh

"tv off"

lgtv off

"tv yt <query>"

$SCRIPTS/yt-search.sh "<query>"

If the user says just "tv yt" with no query, launch the YouTube app instead:

$SCRIPTS/launch-app.sh com.google.android.youtube.tv

"tv stremio <query>"

$SCRIPTS/stremio-search.sh "<query>"

If no query, just launch Stremio:

$SCRIPTS/launch-app.sh com.stremio.one

"tv music"

First run wake-if-needed.sh if the TV may be off, then:

$SCRIPTS/music.sh

"tv <app name>" (app launch)

$SCRIPTS/launch-app.sh <package>

"tv status" / check power status

$SCRIPTS/check-power.sh

Wait for app focus

$SCRIPTS/wait-for-app.sh <package> [timeout_seconds]

---

Configuration

Edit scripts/config.sh to set your TV's IP:

TV_IP="192.168.0.x"

All scripts source this file. $ADB and $CHROMECAST_ADDR are derived automatically.
