I bought de BRP09B42 with the cable, the side of wifi controller fits, but the connector on the board inside the Daikin unit is different. So now we should know how the pinout must be of the wifi controller to the diakin unit mainboard. On the french forum I also don’t see the pinout somewhere?
Hi,
I solved it how to connect the old wifi module. You need to buy the BRP069B42, and the EKRS21 cable (Daikin S21 reducer kit for Stylish)
Than you can connect the old wifi module, and shut down the new version, and you can use the integrated daikin module from homeassistant.

Does the new Daikin cloud app carry on working if you do this, or does the old wifi module take over?
You can choose to use both at the same time, so the cloud wifi adapter en de local wifi adapter. I did shut down the cloud adapter.
I did de wifi module RRP069B32, upgrade to 1.2.54 and that was no issue. The app tells maybe to upgrade later in the future, but if I use the wifi module with hass, I don’'t think about using the app from dakin. I don’t think the module itself checks for updates without the app.
I would not have any objections to connect to Daikin cloud directly. Same as it is working for Xiaomi Miio - Home Assistant integrations. Seems like more cleaner approach, then installing legacy WiFi adapter to units, which already have a WiFi with daikin cloud.
By the way Google home has direct integration to Daikin residential app. Also from references to external sites from above posts I can see that connection to cloud is already being reverse engineered
So fingers crossed, that in future this will be implemented to home assistant.
What I hate these new WiFi integrated units (I have two of them) is that stupid WiFi ssid broadcasting. Hate them for that.
I have one “standing” daikin unit FVXM35F, which does not have integrated Wifi. It has BRP069B41 wifi adapter installed and is connected to my home assistant instance. But Daikin residential app cannot add it to daikin cloud with this error:
Device cannot be added This device can not be added because the region of your device is not supported. Please contact your Installer for further assistance.
Region: EU.
Strange Daikin position, as nobody answers to my support requests
I bought this cable and this is working perfectly well!
Just got new airconditioning installed a week ago and very unhappy that I’m now locked into the cloud system.
I just don’t understand this move from Daikin, other than data snooping. All the server costs will be massive for them and I surely hope they don’t consider going to subscription based models after a while.
For now what I find is that the responsiveness of their cloud system is pretty shit. Often times the shut down command doesn’t get through and you have to do it 2 or 3 times. Same with the settings, once you activated the device through your app and you change something with the remote, the unit will just shut down.
So the units themselves are great, but man I’m disappointed about this cloud bullshit.
For pricing reasons, I think @Malento that indeed this is a very smart move from daikin point of view, since here the cloud will be costing very few per engine.
There are two things from my point of view:
1/ even with the cloud interface, this would have been totally possible to allow local control on a local api
2/ all other providers with cloud based experience) (netatmo, somfy, …) allow people to create their own api secrets to permit custom integrations. It’s a shame that Daikin is not proposing this.
Be an informed consumer and don’t buy products that only offer a cloud based application interface.
I requested my (yet to be installed) Daikin unit be compatible with the BRP15B61 interface or I would look elsewhere.

That’s kind of a dick statement to make and pretty ignorant to how the world works.
We’re talking about airconditioning units which main function is cooling a home. All the smart home functions are a byproduct.
And you might think you’re safe with your chosen interface, but if Daikin decides to stop support or move it to cloud only as well, you’ll be in the same boat. I hope you can rock on without issues, but calling people uninformed with these kind of situations shows little empathy.

Please read our code of conduct and keep it polite.
I’ll be fine as once in and operational I am in charge of any (unlikely imo) firmware updates that could potentially disable local control.
Not the way I do things. If it does not work how I want with my home automation I don’t buy it. If you and others did the same and supported manufacturers that offer a local interface we’d see more support for this.
Bad news everyone. A new version of the Daikin Residential Controller app was just released and it is offering firmware update 3.9.8 for the old controllers (I’m on 3.8.8).
It explicitly says this in the release notes:
Meaning they are probably removing or breaking local control even for the existing models… and forcing everyone to the cloud.
I have an order open for an extra airconditioner (Stylish model) and if it can’t be controlled locally as I read here I will cancel the order. Lines in the sand have been drawn.

Not completely correct I think.
After updating my units to 1_14_18 I indeed lost connectivity to Daikin Online Controller, but the local API is still available.
I don’t know if the API is effectively broken on 1_14_28, which is the latest version.
The Daikin Online Controller basically uses the local API in my case and doesn’t require a password or key to detect and use the units. It’s possible they have only changed the “out-of-home” part but I’m not going to test that to find out as I exclusively use HA and HomeKit. I already took a huge gamble to update to 3.8.8 last time.
Worst of all, none of these updates have ever improved or added anything. There is even stuff I can get working using the local API (Humidify on my Ururu Sarara) but they never bothered to add it to the app.
I would be ashamed if I was on that dev team personally 
I just sent the following email (in Dutch) to the Belgian info-address.
Until some time ago, Daikin indoor units, either from factory or retrofit, were equipped with a WiFi module type BRP069A* or BRP069B*
These modules were controlled by the Daikin app via a local API which also makes it possible to integrate them with home automation systems.
New devices today are often equipped from factory with the module BRP069C*, which no longer offers the possibility for a local API. Operation is only possible via a cloud connection. This has important disadvantages, such as not being able to integrate with home automation systems and the loss of control via the app when there is no internet connection.
I have the following questions about this:
- Is the local API on modules BRP069A* and BRP069B* also guaranteed in upcoming firmware updates, such as the version 1_14_28 for these modules?
- Will a local API be provided on the modules BRP069C* in the future, so that control via home automation systems is possible
- If yes, in what time frame?
- If not, will it be made possible for third parties to connect to the Daikin Cloud services so that these frequently used functionalities can be used again.

Thanks for doing that. I was about to do it, but you beat me to it. Hopefully you get a meaningful response. If you look at the google play store and the reviews and Daikin’s responses it just show they don’t have their IT under control and a local api is preferred. Somehow every problem is caused by excess logging on their server.
Hi all.
So, Daikin Belgium is lightning fast, given this is a deep technical problem and not “which A/C would you recommend?”
This is the (translated) response:
-
For the type BRP069A* or BRP069B* I don’t know that the local API would disappear. I can’t promise you anything but there is no reason at the moment.
-
We are asking to release a local API for the C version, but at the moment Daikin Japan is having a hard time about that. We hope that one day it will come, but convincing a Japanese is not easy.

There is an option to sign an NDA with Daikin Europe to access the cloud API. There are already a few requests and Niko is ready. Extra information. This NDA is only available to companies.
I would suggest everyone to email their local Daikin representation
