Support for Sunsynk via SmartHome Integrations / DeyeSmartDongle

[mdeakin99]

Is your feature request related to a problem? Please describe.
I have managed to read/write to my SunSynk inverter using https://smarthomeintegrations.co.za/product/smartdeyedonglev4-international-shipment-self-flash-firmware-bundle/ and the associated EPS device it creates. I have manage to update all of the sensors but would like figure out how to force charge/discharge etc as these services dont appear for the integration

Describe the solution you'd like
Get the integration working with predbat. Share the output/setup of the integration with anyone else that needs it in the future.

Describe alternatives you've considered
I tried using https://github.com/kellerza/sunsynk/ but couldnt pull data from the inverter. This option requires less hardware and the adapter doesnt need to be near the Home Assistant instance.

Additional context

Let me know how best to share what information I have currently. I am happy to test anything you need me to given you might not have access to this inverter yourself.
