EV data injection thorough MQTT

[hp197]

Describe the bug I have a problem with injecting data through MQTT. Mains seems to work, but EV keeps getting into NO_COMM error.

*** mqtt_receive_callback, is debug added by me just before the UpdateCurrentData call when [topic == "/Set/EVMeter"] (Line: 2566).

To Reproduce

Expected behavior No EV_NOCOMM error.

Screenshots

P.S. The documentation should be updated that injecting EV data requires 5 parameters (L1:L2:L3:W:Wh) instead of 3 (with the mains meter). I can do this afterwards.

Data in MQTT:

SmartEVSE-39644/Set/MainsMeter: -72:-55:-39
SmartEVSE-39644/Set/EVMeter: 0:0:0:0:1565180

This is retained data and updated every 5 to 10 seconds (depending how long the modbus query took).

Have you tried with a little lower value then 1.5MWh?

[hp197]

You mean with the Wh value in EV? Yes, I also tried with -1. This parameter is this value in the webinterface:

I read this as the total kWh handled by the meter as per this piece of code:

            if (WH > -1) {
                // Energy measurement
                EnergyEV = WH;
                if (ResetKwh == 2)
                    EnergyMeterStart = EnergyEV;             // At powerup, set EnergyEV to kwh meter value
                EnergyCharged = EnergyEV - EnergyMeterStart; // Calculate Energy
                RecomputeSoC();                              // Recalculate SoC
            }

Setting it to -1 results in the same EV_NOCOMM error.
