Charging stations: drivechain/charging stuck "false" after 3-phase to 1-phase switch

[Tonno87]

When a phase change occurs from 3-phase to 1-phase during a charging session, the MQTT parameter 'drivechain/charging' does not update correctly.

Before the phase switch, this parameter is reporting true as expected when charging. After the transition to 1-phase charging, it remains false and no further updates are published to this topic.

This prevents the 'Charging Stations' extension from functioning correctly, the soc is no longer updated while charging.

@Tonno87 can you gather the MQTT raw message logs during the switch?

I have a feeling charging is technically stopped and then restarted as 1-phase so the gataway enters "deep sleep mode".

Technically it should go into the "looking for charge start" as the car is shut down (is_charging = False -> hv_battery_active = False), and that should poll every 2 minutes or so

You are right: My easee stops charging for a few seconds and restarts the charging process again.
I wrote an automation to fire up a gateway refresh in this case, then this error occurs:

@Tonno87 can you gather the MQTT raw message logs during the switch?

In the next days, car is full now 😄
