Alfen Eve Pro EV chargepoint interface via TCP modbus

Yes, I tries to consume the maximum available power and changes phases and current in both directions. If the current is less than 6A, it stops charging

That’s great, that’s a feature missing in evcc!! Will test asap I have the DM in Belgium, have a look later at the code, thnx for sharing!!

I expect the DM this summer, so I am already testing it now. There is no impact yet if there is an issue with it

didnt look at your code, but if you dont have an DM, how are you getting data from your analogue meter? with some smappee or shelly tool ?

EDIT: a quick look, i see you created helpers, isnt it better to make them yaml too, easier to copy/paste if you want to share your code, cause you probably created them using UI and edited the options there?

Edit2: did you also configure your Alfen? Probably not? You just disabled load balancing and solar charging there, since you use the integration to configure those? If not, maybe some screenshots of you Alfen config can be usefull too?

Edit3: you are checking every 10 sec, isn’t that an overkill? That means you are changing current quite a lot on the evening when you are home , the captar is limited to 15 min, maybe checking like every 5 min instead of 10 sec is more then enought? Or if you check like > 6000 for xx min ?

Or why did you choose 10 sec?

i open an issue on github, maybe we can discuss there :slight_smile:

Dude, this is awesome! :slightly_smiling_face: Me as an enthusiast but not a programmer can learn so much from this!
I will try to adapt your automation and script to my needs, Thank you for sharing! :+1:

its indeed awesome, also changing it for my needs, gonna create a simplified veersion

Hello,

I successfully installed the Alfen integration from leeyuentuen yesterday. Is it possible to start an automation if a special RFID tag is placed on the wallbox?

Thank you.

Best regards

Just start new project (still in alpha) to use TCP Modbus in home assistant

advantage: multiple connection possible
disadvantage (atm) only read, no update.

still just a start, still need to add more address based on the documentation

Is it the ± the same as : GitHub - ThaStealth/alfen_modbus: Alfen Modbus Component for HomeAssistant

Great, then i don’t need to continue with that project.

I never tried it, I’m using your http version

Advantage of modbus, multiple connection possible.

Was maybe to think to combine modbus and http version.
Modbus to get the data, and the http to do to changes

Sounds like a bright idea. Modbus is able to check the status on an ongoing basis and only when a change is needed to one of the parameters we open a connection, make the change and close the connection again. The only risk is that another application keeps the connection open and ‘we’ will not be able to make any adjustments.

Are you still considering resuming this? The other option: GitHub - ThaStealth/alfen_modbus: Alfen Modbus Component for HomeAssistant

Hasn’t seen any recent development and doesn’t seem to work right now.

could you please continue? The ThaStealth integration is not working well anymore and it looks like it is discontinued
