Hi all,
I got my new EV Charger integrated into Home Assistant and thought others might find that useful.
Code here
Firstly credits to SmartyVan, I had some basic Home Assistant MQTT integration setup but his video and code is next level…!
To get this working I thought would provide the steps as it wasn’t straight forward 
Steps
Physical install of the Victron EV Charger Make sure that the firmware is updated, this has to be done either via the VRM portal or locally you will be best to ask the installer as the firmware is only available to those with a Victron professional account. If you have any issues installing the firmware install it at least twice preferably locally. Yes that sounds strange, but it worked for me.

Configure GX Firstly update the firmware on this via the VRM portal. You need a relatively new version of Venus OS to work properly. 5. Setup, configuration & operation My EV charger did not automatically appear and I had to search and manually update
Configure EV Charger Follow the manual to connect the EV charger to your WIFI. Make sure it’s the same network as your GX device. Configure the GX device comms and also include the GX in the whitelist. Check comms if this doesn’t pass you must resolve that first Manual - EV Charging Station
Solar forecast If you would like to include the solar forecast you can refer to this. GitHub - BJReplay/ha-solcast-solar: Solcast Integration for Home Assistant
You should now be able to see the EV Charger in the GX (and VRM portal) and from the EV Charger see stats like solar, battery etc
Please use my example code and you should be able to get a dashboard with controls up and running.
