PV divert and BMW i3

Hello all.

I am eventually able to use the PV divert feature on my OpenEVSE.
I had a tiny MQTT issue (had to reboot the wifi to get it to work) but the OpenEVSE now gets the updates and is able to modulate the charge.

However, I have an issue that seems specific to the i3.

When OpenEVSE lowers the charge (under 6A, even going to zero amp), instead of going in pause, the i3 goes into error.
It says the charge was interrupted and stays in this error mode until I manually disconnect/reconnect the charging cable.

I encountered the issue a couple of time when I was not using PV divert but modulating the charge manually: going down to 6A ended with the same “interrupted charge issue”.

Any idea of a specific parameter to deal with this?
