My working Compleo (innogy) eBox Smart override

[toszlanyi]

Hello people,

Just wanna share my modifications to this ocpp integration to operate my eBox S to my needs.
Main goal was to protect the hardware, especially the contactor to keep it alive as long as possible.
The principles are well documented inside the code but the main feature for this override is:

• start a session under minimum load (6A) and ramp up to the target current after the contactor is confirmed closed
• stop a session by sending a TxProfile of 0A which prevents the contactor opening under load
• use of existing _maximum_current ui slider, only sending TxDefaultProfile and TxProfile (didn't want to create another one as my eBox max current is always at 16A that I never change)

@lbbrhzn - maybe that hardware protection concept is a general optimization method that could be used upstream, in case all other wallboxes follow the same principles.

I also got some additional sensors worked out.

• cumulative energy meter as the eBox doesn't propagate one
• an additional charge percentage meter for the car SOC difference
• a German translation for the connector status ("happy wife, happy life")

I've got many more, like a sophisticated solar surplus charging automation etc. ...
So tell me what you think and also if you find more improvement capabilities. Cheers!

!!! DON'T JUST COPY / PASTE !!! UNDERSTAND THE CODE AND DECIDE FOR YOURSELF WHAT TO DO !!!

The file ebox.py just needs to be copied inside the ocpp folder and linked in api.py - details in the code header:

Template sensors are in this yaml file:

PS: The cumulative energy meter requires the eBox firmware fix published with version 3.0.4
