Automations with OCPP / PV excess

[nrace87]

Hi
I just wanted to ask if someone has already made some nice automations with the OCPP sensors. My idea is a simple PV surplus/excess EV charging.

I tried with EVCC already and I like the design a lot but for me it is not working/the right way. So I just want to check what would be transfered to the grid and then start charging with 16/14 amps and maybe check every 20sec if the power to the grid and to the car are matching and correct it then with occp amps in the range from 6-16 amps.

So I am really happy for ideas how you maybe already did it like this. Maybe to share some blueprints and ideas.

Thanks a lot :)

Have you seen the blueprint from here:
[ha-blueprint-autel-ocpp](https://github.com/mavnz72/ha-blueprint-autel-ocpp/blob/main/Blueprint/EVSE_Solar_and_Free_Power_Charging_Controller.yaml)

It is quite informative

I have written one in pyscript for a multiple charger installation, but it is not quite ready.

Oh nice, thanks a lot. That's quite close to the function I am looking for.

I will try to adopt this for my ABB Terra AC Wallbox or maybe it is possible to do it quite general. Hope there will be some sun here then to test it 😄

Man that looks great (Just looking at the code)! No idea how to make it work, but might have to try and figure it out.

Looking at EVCC but need to use the MQTT feature to get information from Solar Assistant.

I do have 2 EVs so have anything that handles two would be ideal.
