Bluecorner (BLINK) Electric Vehicle Charger (EV) Active Load Balancing

Third party integrations

I’ve got a Bluecorner Curved Pro EV Charger installed with the OCPP server owned by Bluecorner (for billing of company car). It is connected to my smart meter to protect the grid connection from overload. I’d like to take over this connection with home assistant to throttle charging based on my solar output and grid prices. It is modbus RS485

communication so I was hoping to ‘fool’ the EV Charger into thinking it is overloading the grid connection and thus reduce charging amps to the car.

I’m planning on using an Elfin-E11A,edit: can’t get this to work so I’m going for an esp32. Keep you posted

Update: I’ve managed to read out the modbus of the eDP1B device, screenshots attached. For the rest of the integration, I’ve bought an esp32 to follow the guide mentioned here: GitHub - thomase1234/esphome-fake-xemex-csmb: ESPHome Modbus Server/Slave component to fake the Xemex CSMB
