@Pukka not quite sure I understand about selecting the source, if you do not want the demand sharper or solar then these can be turned off.
The new divert code will play nicer with other ‘sources’ and hopefully not conflict with them.
We i need one of the new wifi esp32 for the new features?
The initial version will be on the ESP32 but once stabilised and tested will be back ported to the ESP8622
The new code should be much better at managing the charge so hopefully you will not need to interact with it. For the existing version I would suggest switching to ‘Normal’ mode rather than unplugging the car.
Thirdly: can the charging rate be reduced below 6 amps. On my Tesla M3 I can reduce the charge rate to 4amps if using the granny charger cable, the OpenEVSE lower limit is 6 amps.
@glyn and I have spoken about this. Officially the min charging rate is 6 amps, but we know at least the Tesla can go lower. Any change in this area would need a firmware change on the EVSE, not just the WiFi module.
