Predbat and EVCC

[zlakes01]

I use both Predbat and EVCC (Electric Vehicle Charge Controller) and both works fine. The reason I use EVCC is several charging modes including Solar charge. The issue is control of the home battery when EV is charging. I have tried with different automations but no of them was very reliable because of to meny parameters. There is a switch in Predbat switch.predbat_car_charging_from_battery that I want to use but if possible it will follow EVCC charging sessions. There is two binary switches binary_sensor.evcc_garage_charging and binary_sensor.evcc_driveway_charging that should trigg switch.predbat_car_charging_from_battery. Is it possible?

I red #2805 and the documentation. My setup for car charging works as it should. I have two cars and two chargers and Predbat calculate charging slots with kWh for car charging considering electricity price and stop battery discharge. I want to maximize PV usage so when pv production is enough for EV charging, EVCC integration start charging, in that case I need to say Predbat to stop battery discharge. I try to use car_charging_now. If I underseen it correct car_charging_now works only if Predbat car charging is enable (Hold for car is present). Is it possible to override Hold for car and use only car_charging_now in order to stop battery discharging?

It works as I wish when switch.predbat_car_charging_plan_smart is off and car_charging_now is active. When charging demanted from EVCC starts than Predbat calculate car charging slots and stop battery discharge.

One more question. When Predbat is in status "hold for car", it trigg "no discharge" which works well. It possible to change action when "hold for car" to "feed in priority"? Or even better, make it possible to choos which one would be active.
