export HA_URL="http://your-ha-instance:8123"

Or create a .env file in the skill directory (auto-loaded by ha.sh):
HA_URL=http://192.168.1.100:8123
HA_TOKEN=eyJ...your-token...
The CLI wrapper also checks $HOME/.config/homeassistant/config.json as a fallback
(JSON with url and token keys). Protect this file with restrictive permissions
(chmod 600) since it may contain your token.
curl -s -H "Authorization: Bearer $HA_TOKEN" "$HA_URL/api/" | jq
Or with the CLI wrapper:
scripts/ha.sh info
Note: Node.js is an optional dependency, only needed for inventory.js.
If Node.js is not available, ha.sh inventory falls back to a curl+jq listing.
node scripts/inventory.js
This generates ENTITIES.md with all entities organized by domain, including name, area,
and current state. Read ENTITIES.md before acting on devices to know what is available.
If running inside Docker:
http://192.168.1.100:8123http://homeassistant.ts.net:8123homeassistant.local often doesn't resolvehttps://xxxxx.ui.nabu.casa (requires subscription)This skill implements a layered safety system to prevent accidental actions on security-critical devices.
Always confirm with the user before performing these actions:
cover.* with device_class: garage)Never act on security-sensitive devices without explicit user confirmation.
For critical domains (locks, alarm panels, garage doors, covers controlling physical access), follow this workflow before executing any command:
Important: The agent (not the script) is responsible for enforcing this confirmation
flow. The CLI wrapper (scripts/ha.sh) checks blocked_entities.json as a hard block,
but interactive confirmation must be handled at the agent conversation level before
invoking any command on critical domains.
Users can permanently block entities by listing them in a blocked_entities.json file:
{
"blocked": ["switch.main_breaker", "lock.front_door"],
"notes": "Main breaker should never be automated. Front door is manual-only."
}
Blocked entities cannot be controlled under any circumstance, even with user confirmation. Check this file before executing any action if it exists.
The scripts/ha.sh CLI provides easy access to all HA functions:
