Charging with Smart4four EQ and Renault ZOE is no longer possible from version 3.6.0

[Elektrofix-OL]

Describe the bug
I built a wallbox for a colleague. The Smart4Four can't be charged with 3 phases.

To Reproduce
Steps to reproduce the behavior:

1. Connect the plug to the vehicle, no charge
2. Firmware to 3.5.1
3. Connect the plug to the vehicle, charge
4. Firmware to 3.6.0
5. Connect the plug to the vehicle, no charge

Expected behavior
That the Smart4four charges on the wallbox in the same way as a Smart4two

continue exams
Before we changed the software, we swapped the hardware from a SmartEVSE 3.7.2 to a SmartEVSE 2.30, because the Smart4four charges easily on another wallbox of mine with a SmartEVSE 2.0x.

It seems as if the SmartEVSE from 3.6 has changed the modulation on the CP, so that the Smart4four cannot cope with it.

The only way I can think of pinpointing this problem is if you go to the middle of the list, e.g. :
git checkout 5d99287
pio run -t upload
.... and see if the problem still exists. If it does, go down on the list, if not, go up, until you find the commit that causes the problem.

Then we probably understand what is causing the problem and we can probably solve it easily.

I understood you had problems in the past compiling from source, are you wiling and able to do this?

Try setting MinCurrent to 7A, this helped with a Kona:
#40 (comment)

[mbuijs]

FWIW, I updated my SmartEVSE v3 from serkri's v1.7.2 to v3.6.10 in 1 step a few weeks ago. My Zoe ZE40 has been charging properly on a daily basis.

MinCurrent is set to 6A in my config.
