Daikin integration issue with new unit BRP069C4x

The problem

Hello,
I just bought new Daikin air conditioning. Based on model BRP069C4x. I already have an older one "B4x" perfectly integrated. With the C model when I try to integrate I receive an unexpected error message and it is impossible to integrate my units.

Hello,

I'm coming back to you because I dug a little deeper into the subject.

If I understand correctly, Daikin has just changed its communication policy with its air conditioning units. It would no longer be possible with “C” models (BRP069-C) to control them locally directly. I just installed the "Daikin Onecta" integration (using API) instead of the "Daikin AC" and everything works very well, even with the old units. In return, internet use obligatory.

For air conditioning this is not very critical. We're not talking about home protection. It'll just be too hot or too cold or nothing at all, and go back manually isn't that difficult.

Note that new information appears with the Onecta integration, including for old units (under Daikin AC). It's not just a change of method. For example the daily, weekly and annual electricity consumption (fine for graph). The new features of the Onecta interface (smartphone) go back to the integration.

If there is another solution I will look at it closely but for now this one (Daikin Onecta) suits me perfectly

Thanks.
