EM2GO Home: Workaround for old fw current and phase setting #16201
base: master
Are you sure you want to change the base?

Yes that is correct, but not with the old fw version. |
Then there should probably be two different templates for the Home |
For this purpose, we are setting "mA" capability in the charger golang file if the new firmware is installed:

which is nice. |
Agree. That's how I found the EM2GO Home in the first place. |
Very well. We have added mA capability in the template and set mA support in the charger when not using the workaround. |

Should that not better be placed before enabling again?

In general you are right, but the chargers old fw is always starting with 3p, even if we send the command in the first place. That´s why we first need to enable it, then set the phases, This is happening within 60ms, so it should not be an issue for the EV.
Hello guys, |
We‘ll check about that. May add an extra ModBus register (for fw ≥1.3.) How does Opel EVs behave, when the delay is less than 120 seconds? Will it throw an error? |
We would like to you to consider the following PR as a workaround for the EM2GO Home charger to address the following issues:
This PR tries to fix issues mentioned in EM2GO - Phasenumschaltung (EMH011AC1RW) #12382, em2go startet immer bei 11kW - PV Modus - Regelt nicht schnell genug - bricht ab #14307, EM2GO-Home Probleme mit (Modbus-)Verbindung & Phasenumschaltung #14488 and evcc & EM2GO-Home Wallbox & KIA EV6 - Lade- und Verbindungsabbrüche und keine Phasenumschaltung / aktueller Stand #14643.
The workaround should only apply, if the firmware is <1.3 which will be tested by sending a current setting of 6.1A to the charger. If the returned value is 6A, the firmware is <1.3. If the returned value == 6.1A then it is assumed, that the firmware is >=1.3.
