Extend existing Charge controller for charging Electric Vehicles with OCPP and WiFi communication

Extend an existing charge controller for charging Electric Vehicles with Wifi and communication with an OCPP Backend. I want to make an existing semi smart charge controller capable of configuring trough wifi and able to communicate with an ocpp Backoffice. I want to remove the screen and configuration only trough wifi. Capabilities today are: - Smart charging capable, reduces charging current when demand elsewhere increases. - The load balancing feature allows you connect up to 4 controllers to one mains supply. - Switched 230Vac output, for contactor/relay. - Can be used with fixed cable, or socket and charging cable. - Automatically selects current capacity of the connected cable (13/16/32/63A) - Locking actuator support, locks the charging cable in the socket, automatically unlocks on a power failure. - Powered RS485 communication bus. - Built-in temperature sensor. - All module parameters can be configured using the display and buttons. - Firmware upgradable. - The controller operates at a mains voltage from 110-240Vac Important part is this: The controller will be build with the following service => [login to view URL] So you will need a bom and gerber file. You will also be able to see if the parts are available and common. The project of the existing controller is located at the following address: It is this controller I want you to extend and rewrite [login to view URL] THE CONTROLLER SHOULD MAINTAIN ITS EXISTING CAPABILLITIES AND MUST BE ABLE TO COMMUNICATE WITH AN OCPP BACKEND
