Daikin Cloud Controller - BRP069C4

[dorenberg]

So I guess we have to wait a bit. I have no clue how to fix it.

Hello,
I read all this post, and thanks for this good work based on nore-red. That's very impressive.
However, does anyone have a similar solution compliant with the new offical API here using OIDC auth ? https://developer.cloud.daikineurope.com
or any other solution (python ....) able to interface domoticz with this new daikin API. Thanks.

In this discussion Daikin AC is also discussed: viewtopic.php?t=21126&start=80

Thanks @waltervl for your quick answer.
So today, there is no straigthforward solution.

Hi All,

I had the same problem you are facing and I am now working in a concept that can integrate the Daikin Cloud API on any platform.
I am using NodeRed to call the Daikin API.

Next step is to publish the retreived values from daiking on MQTT so any platform can ingest from there.

It is not finished yet but here are the steps of this concept.

1. Create an account in the developer portal of Daikin.
2. Create an app.
3. Use Postman to make the first connection using OpenID. The return URI used is https://oauth.pstmn.io/v1/callback (select the option Authorize using browser.

Once this is done you can get the first acces token and refrersh token.

From here you can use "normal" https calls to refresh the access token. I created a sqlite database where I store the Access token and refresh token. This access token I can use in NodeRed the call the api functions of the daikin api. When the access token is expired I can call

POST https://idp.onecta.daikineurope.com/v1/oidc/token?
grant_type=refresh_token
&client_id=[YOUR_CLIENT_ID]
&client_secret=[YOUR_CLIENT_SECRET]
&refresh_token=[YOUR_REFRESH_TOKEN]

In nodeRed I can build this URL using the client_id and client_secret of the created application and the refresh_token I stored into my database.
The response is a new access token that can be used to make new calls to the api. And so on.

So this is not a shippable solution but I have the concept working. When I am finished with my project I can try to upload that here.

Thanks hetisweergezellig,
Your strategy is promising. Yes I'm very interesting in your solution as I already have MQTT devices working in my side!

Hi,

I am also very interesting in this solution.
I have a working MQTT and NodeRed and also an account in the developer portal of Daikin.
i tried different solutions but with no luck to connect to my Daikin Airco yet.

Probably a strange question...

I used to own Daikin airco's myself... And have build native support for it in Domoticz

Does this not work anymore?

[INendels]

The daikin lan interface in domoticz is for local control, my airco is now 1 year old, but can not be controlled localy.

Only through the cloud api. But i have not found a working one for domoticz or node-red

@Gizmocuz: on recent units there is no LAN interface anymore... so your native support can't control them.

Daikin has opened a cloud developer portal, but there are severe limitations on the number of calls per hour/day or so. So severe that it's simply unusable for me. They don't even differentiate the limit in function of the number of units you have (8 in my case). I also understand that the functionality is rather limited (for the time being ?).

One of my 8 units doesn't have a LAN interface, so I installed a Faikin module. Works better than the original LAN...

[INendels]

Do you have a link for this module, so i can see if i can use it in my daikin airco

[INendels]

Found it, it is open source esp32 module. This can be connected to a daikin s21, x50 or s403 connector.

At first i thought it was a typo because the f is next to the d.
But it is a real faikin module

Ordered it from amazon, so i can test it, can coexist with the original wifi module.
