MG/SAIC CUSTOM INTEGRATION

Important Notes:

• Using this integration causes the MG/SAIC mobile app to shut down, as per API requirements, since only one device can be connected at a time. Logging into the mobile app causes this integration to disconnect and fail to set up.
• This Integration has only been tested on a MG Marvel R model. Please provide feedback on sensors and information for other vehicles.

4. On the "Repository" field put the URL https://github.com/ad-ha/mg-saic-ha. On the "Category" select "Integration" and click "ADD"

6. Search for "MG SAIC" and download the repository.
7. Restart Home Assistant.

Manual Installation

1. Download the latest release from the MG SAIC Custom Integration GitHub repository.
2. Unzip the release and copy the mg_saic directory to custom_components in your Home Assistant configuration directory.
3. Restart Home Assistant.

CONFIGURATION

1. Go to Configuration -> Integrations.
2. Click on the "+ Add Integration" button.

Version History

0.2.1
- Revised vehicle type identification mechanics and conditions - closes SOC not showing in HA #6
- Added new step to config_flow to allow users to select the correct vehicle type if the integration fails to do so based on API data - closes SOC not showing in HA #6
- Added configuration options to the integration to manually change the update intervals.
- Revised translations

0.2.0
- Revised mechanics for connection with API and data retrieval
- Services testing and adjusting to API requirements
- Renamed and revised sensor data and info
- Revise units for sensors and adapting all sensors to SensorDeviceClass from Home Assistant
- Revise Unique ID generation for all sensors
- Revise Login method to avoid blocking calls during startup
- Improve detection and discard of "Generic Responses" during API setup and updates
- Improve vehicle type detection on integration setup.

0.1.0
- Refactor code to work with data coordinator
- Revised mechanics for connection with API and data retrieval
- Update saic-python-client-ng requirements to version 0.2.3
- Added new sensors for charging data
- Renamed and revised sensor data and info
- Revise config_flow to allow login with phone and email
- Initial implementation of services (some services still not available, but are implemented as a proof of concept). _Feedback on this will be helpful_
- Change update interval to 5 minutes once charging is detected
- Refactor API responses and values as needed. Charging sensors only display data if Charging is Active, otherwise 0 will be displayed
- Fuel Level, Fuel Range, EV State of Charge and Electric Range are vehicle dependent. Add logic to determine the vehicle type and show sensors accordingly.

0.0.2
- Revised mechanics for connection with API
- Added new sensors (Brand, Model and MY)
- Rename sensors based on Brand and Model
- Rename sensors to have them grouped by type (windows, doors, tyres...)
- Revise config_flow (_login with phone still not working and unavailable_)
- Initial trialing for charging details 

0.0.1
- Initial release

TO-DO

• Implement initial services for Locks action, AC control and ancillary services.
• Implement charging detection and corresponding sensors.
• Check API details for energy usage and stats, adding additional sensors.
• Check implementation against other EV/PHEV models.
• Add possibility to display metric or imperial data, including tyres' pressure.
