German §14a EnWG compliance #26
Description
I am now trying to extend the fake csmb for using another GPIO pin of the ESP32 so that I can use the grid operator switch device for power dimming <= 4.2kW in cases of high load on the grid. I want then to register the wallbox as a device compliant with the German §14a EnWG (controllable consumption unit). For these types of devices, cheaper prices per kWh are available from many vendors, currently around 20-22 €ct/kWh. Anybody else around who has done similar things already? Please share your approach!
