Node Home Assistant

Home Assistant utility library and command line interface

NOTE: This is a work in progress ymmv. Currently it's working in my very limited testing and uses the Server Sent Events interface Home Assistant surfaces along with the REST api.

Usage

Use as a command line tool

1. Install the module npm install -g node-home-assistant
2. Add an environment variable with your Home Assistant URL and Password exported as HA_URL and HA_PASSWORD
3. Run ha history as a quick test
4. See other commands and examples by running ha with no other options
5. The command line tool surfaces a lot of the defaults and configuration via environment variables, checkout config.js for a listing

Use as a library in your own project

1. Install module locally npm install --save node-home-assistant
2. Check out the _examples directory in this project which shows some usage of the API and Events listener interfaces
3. Quick example below:

const HomeAssistant = require('node-home-assistant');

const config = {
    baseUrl: 'http://localhost:8123',
    apiPass: 'supersecretpassword'
};

const homeAssistant = new HomeAssistant(config, { startListening: true });

// Call a service with domain, service, data
homeAssistant.api.callService('light', 'turn_off', { entity_id: 'light.office_hue_room' })
    .then(res => console.log('Light switched off', res))
    .catch(e => console.log(e));

// Events by event_type as sent by home assistant ('state_changed' and 'service_executed' from home assistant below)
homeAssistant.events.on('ha_events:state_changed', (evt) => console.log(`(ha_events:state_changed) ${JSON.stringify(evt)}`));

TODO

• CLI option to call service
• More tests
• Finish CLI Dashboard
