EV car charger control from HA Modbus
Posted: Sat Dec 13, 2025 6:30 pm
Hello,
I have inverter H1-5.0, battery EP5 and EV charger APEX-7S .
I have a Citroen car which does not natively manage the % of charge limitation.....
On HA
- I have a foxess ModBus add on
- the Citroen add-on ( but as it is unofficial, I do not know how long it will work).
So I would like to create an automation to start and stop the car throw EV charger ( like it is possible to do in the application ) depending on the car state ( connected and % of charge).
But I do not find EV charge capability on the modbus add-on (only fox battery management).
Is there a way to manage the car charger from the ADD ON or adding this capability ( as it can be done throw the Foxess app, I guess the back functionality exists.
I am not a developer expert, but still a developer and I can help if needed on the HA add on development
Thanks
