Node-Red module for streaming Easee charger data.

## Features

- SignalR streaming client
- Pre-defined list of REST API GET/POST commands
- Custom commands through REST API

## Howto

`npm i @runnane/node-red-contrib-easee`

Add the `easee Charger Streaming Client` node
Configure the node with username/password and the Charger ID.

## Streaming node

Configure the node with username/password and a Charger ID ("EH000000").
Streaming telemetry from the signalR enpoint will be available in the fourth output,
the `ProductUpdate` one.

## REST node

Use the `easee REST Client` node
Configure the node with an account username/password.
The REST node will not authenticate on its own, so you will need to authenticate/renew tokens.
However, if you use the `easee Charger Streaming Client` node,
you do not need to authenticate additionally with the REST node, as the signalR socket
will authenticate and renew automatically.

There are two ways of sending commands:

### Sending predefined commands by topic

Send the your selected command as the topic into the node.
You can set the charger, site and/or circuit variables directly in the node, or send them as
`msg.charger`, `msg.site` and `msg.circuit` to override.
Implemented commands that may be sent as topic, are:

- `login`
- `refresh_token`
- `charger`
- `charger_details`
- `charger_state`
- `charger_site`
- `charger_config`
- `charger_session_latest`
- `charger_session_ongoing`
- `stop_charging`
- `start_charging`
- `pause_charging`
- `resume_charging`
- `toggle_charging`
- `dynamic_current` (Without msg.payload.body for reading (GET), and with msg.payload.body for setting (POST).)
- `reboot`

Example, [get charger details](https://developer.easee.com/reference/get_api-chargers-id-details):

```javascript
node.send({
  topic: "charger_details",
  charger: "EH000000",
});
```

### Sending custom commands

Send the full path as msg.command, and optionally the POST body as msg.payload.
See [get_api-chargers](https://developer.easee.com/reference/get_api-chargers) for full list of commands.
When adding a body, the request will be sent as a POST, else as a GET. If you wish to send a POST without body, add an empty object as POST argument.

Example to [set dynamic current to 3x25A](https://developer.easee.com/reference/post_api-sites-siteid-circuits-circuitid-dynamiccurrent) by doing a custom command with POST body:

Set dynamic current:
```javascript
node.send({ 
  payload: {
    path: "/sites/1234/circuits/1345/dynamic_current",
    body: { phase1: 25, phase2: 25, phase3: 25 },
  }
});
```

Pause charging:
```javascript
node.send({ 
  payload: {
    path: "/chargers/EH000000/commands/pause_charging",
    body: {},
  }
});
```

## Development

### Code Quality

This project uses ESLint for comprehensive code quality and formatting:

```bash
# Check for linting issues
npm run lint

# Auto-fix formatting issues  
npm run lint:fix
```

**CI Integration**: ESLint runs automatically on all pull requests and blocks merging if issues are found.

See [ESLINT.md](ESLINT.md) for detailed ESLint configuration and [MIGRATION.md](MIGRATION.md) for completed JSHint migration details.

### Testing

```bash
# Run all tests
npm test

# Run tests in watch mode
npm run test:watch

# Run with coverage
npm run test:coverage

# Run specific test types
npm run test:unit
npm run test:integration
```

### Continuous Integration

The project uses GitHub Actions for CI/CD:

- **Code Quality**: ESLint checks (blocking)
- **Testing**: Jest test suite across Node.js 18, 20, 22, 24
- **Compatibility**: Node-RED compatibility verification
- **Security**: npm audit for vulnerabilities

All checks must pass before code can be merged to main branch.
