Homeassistant

Home Assistant

The robomotion homeassistant CLI connects to Home Assistant for smart home control and automation. It reads device states and sensor values, calls services (turn on/off, set temperature, etc.), activates scenes, fires events, and queries state history.

When to use

• Control smart home devices — turn on/off lights, switches, etc.
• Read device states and sensor readings
• Call Home Assistant services and activate scenes
• Query state history and fire custom events

Prerequisites

• robomotion CLI installed
• Package installed: robomotion install homeassistant
• Home Assistant URL and long-lived access token configured via Robomotion vault

IMPORTANT: Session Mode Required for Multi-Step Operations

Each CLI command runs as a separate process — connection IDs from connect do NOT persist across calls. You MUST use --session on connect and pass --session-id to all subsequent commands.

Workflow

1. Install (once): robomotion install homeassistant
2. Connect with session:

   robomotion homeassistant ha_connect --session --output json
   # → {"outClientId":"<client-id>","session_id":"<session-id>"}
   

3. Use the returned client-id and session-id in all subsequent commands:

   robomotion homeassistant ha_get_state --client-id "<client-id>" --entity-id <entity> --session-id "<session-id>" --output json
   

4. Disconnect when done:

   robomotion homeassistant ha_disconnect --client-id "<client-id>" --session-id "<session-id>" --output json
   

Always append --output json to get structured JSON results.
