Sample configs for MQTT Home Assistant integration.

### Location
Unfortunately, the MQTT Device tracker uses a home/not_home state and the MQTT Json device tracker does not support
the discovery schema so a manual entity configuration is required.

device tracker yaml:
```yaml
device_tracker:
  - platform: mqtt_json
    devices:
      your_car_name: homeassistant/device_tracker/YOUR_CAR_VIN/getlocation/state
```

script yaml:
```yaml
alias: Car - Location
sequence:
  - service: mqtt.publish
    data:
      topic: homeassistant/YOUR_CAR_VIN/command
      payload: '{"command": "getLocation"}'
mode: single
icon: 'mdi:map-marker'
```

### Lovelace Dashboard
Create a new dashboard, or use the cards in your own view. The `mdi:car-electric` icon works well here.

script yaml:
```yaml
alias: Car - Start Vehicle
sequence:
  - service: mqtt.publish
    data:
      topic: homeassistant/YOUR_CAR_VIN/command
      payload: '{"command": "startVehicle"}'
mode: single
icon: 'mdi:car-electric'
```

TODO
- Utility meter that resets for monthly LIFETIME ENERGY USED. This seems to only be updated after a full charge, along with other data points.
