OpenEVSE was written for and has only been tested on 16 x 2 displays. You will need to rewrite the LCD libraries and LCD display code to support 20 x 4.
The elapsed time counter was only shown when Ammeter was disabled.
This may be what you are looking for...
J1772Controller.h
time_t m_ElapsedChargeTime;
Perfect! Work:)

In the OpenEVSE 5x version, the Charging state displayed the duration of the car charging. I have the 6x version and instead of time I have kW and kWh. I inserted the 20x4 display - I changed the settings and wants to add time to line 3. What should I do?
