[App][Pro] OCPP Server - Run any OCPP 1.6 EV charger from Homey

@nogren

Thanks so much for this app! It will allow me to move away from the cloud based NexBlue app to local control.

Although I am new to this and may have missed something, I do have a question: Why is there an 11kW maximum on set target power? Does the OCPP get this from the charger or is it hardcoded?

I have a 25A circuit so I could do 16kW charging (some cars have a 22kW OBC).
Perhaps an option to set the maximum allowed in the app?

Hi,

I am using OCPP Server v1.0.5 with a Ratio EV charger using OCPP 1.6J.

The charger connects successfully to the Homey OCPP Server, and remote start/stop charging works correctly.

However, whenever I try to set a charging power limit, either using the device slider or the Homey Flow card, I receive:

“Charger reported ‘Rejected’ for charge limit”

The charger continues charging at full power.

Could you please check the OCPP messages in my diagnostic report and see exactly why the Ratio charger rejects the SetChargingProfile request?

In particular, could this be related to using TxDefaultProfile rather than a TxProfile associated with the active transaction?

Being able to dynamically control the charging limit is essential for my setup, as I want Homey to regulate EV charging based on available solar power.

Diagnostic report ID:

abc4cef7-d01c-4d12-998d-7305ad2dc012

If needed, I would be happy to test a modified/beta version of the app with my Ratio charger.

Best regards,

Claus

Hi Claus

This is fixed on newer version (under test)

Can you please try with the test version?

If you send an email to homey@dnetlabs.co i can provide you the latest test version of the app.

Hi

This is very interesring. Does the OCPP Server app support a Ctek Chargestorm Connected 2 with two charging cables?

I can only confirm that it supports the one with one outlet. But perhaps Dnetlabs can confirm that there is code in the app to support two outlets?

Hi!

That I have understood, but thanks for confirming. It would be great of someone can confirm that it works with two outlets.
