Daikin Integration - Updated 2022-09-26

The local API has been turned off on the most common adapter that come with the residential split systems, like the BRP069C4x. It’s cloud only for those.

As was already stated in a previous post on this topic, we are hopeful that Daikin will open the API for local access in the future due to some hints from Daikin Europe. We’ll see.

Meanwhile there are alternatives like Faikin or direct ESP access as also already stated before in this thread.

i did it by myself and it was a lot of fun, but honestly you can’t expect all end user to be able (o to want!) to open their split, create the circuit and all the rest. I fully understand final users to be upset with daikin behavior, even more if really the user experience you get with the cloud API is the one reported by @leviathan400

I’m not saying it’s for everyone and it’s certainly not ok that Daikin has gone this route.

As I said in my post, we are hopeful that Daikin will open the local API again so we can have a proper integration like with the older models.

I just received 4x new Daikin Stylish (MY2023) and 1x Emura (MY2023)
I was able to open up one of the Stylish and found the included WIFI module is a BRP084A42-1
I didn’t see this particular model in the thread here, but I would assume that because it’s an A-series it still had a Local API ?

I also opened up the Emura FTXJ50AB, but the WLAN module seems very well hidden there, couldn’t find. It’s probably under the mainboard ?

Correct.

I just purchased a Daikin air conditioner FTKZ12VV2S specifically because it had built in WiFi.

My fathers house has a Daikin WiFi air conditioner and it was really easy to access the local API so I thought I wouldn’t have any problems integrating it with Home Assistant.

Unfortunately I set it up via the Daikin app and straight away upgraded the firmware, I can’t figure out how to control it via WiFi using anything other than the Daikin app.

What model?

Model:

FTKZ12VV2S

When I visit this URL: http://192.168.0.204/dsiot/multireq

In a browser I receive the message:

GET Method Not Allowed

So I finally managed to locate the WIFI module on my Emura MY23 :

Seems to be a single chipe, which states :
Model Type 1YA SS3404019
2P571193-2F
RC19001-2A

The board states :
E88441 OS-2S
PCML1852

Would anyone know if this the infamous C-series or am I lucky and is it his an A or B ?
It is clearly different to the B-series from my other Stylish units though.

And if this is a C-series, are there any replacement A or B units that would fit the same size ?

It’s a C-series unfortunately. Same as with mine. I’m currently looking into this again and the Faikin ESP32 looks very good or using “official hardware” would be something like BRP069B42 + EKRS21 connected to the S21 Port.

The problem with the BRP069B42 is that it’s quite bulky and won’t fit inside the Emura. Does anyone have experience swapping the C-series with the A-series that is inside the Stylish ?


It seems to be the same 5pin connector.

I don’t know if your units are compatible, but have you looked at the Faikin alternative? They are really tiny.

I just got mine from the UK (I had to use a reshipper to the US) and they are clearly superior to the stock Daikin units. They support MQTT and automatically get discovered in Home Assistant:

I am probably going to sell my original wifi modules as they originally cost $50 each, but now go for over $400 on ebay because the new ones are cloud-only.

I have the Same Problem.
4 Daikin Comfora AC Units, 3 with local Access und the last one with Cloud Controller. I found no S21 Connector on the PCB.


That sure looks like the connector to a jst ehr-5 in your photo.

If I am interpreting it correctly, you should be able to replace that module with an open-source Faikin.

EDIT

Wait, I did some more digging, and it seems that connector is smaller than the jst ehr-5 but your unit should have a X50A connector somewhere on it, which you can also wire into the Faikin controller, or a S403 which should work, but requires more careful effort as that connector has communication and high-voltage pins on it.

S403

I have a Stylish B-model (very recently bought, matt black), with the new BRP069B4x WiFi module. Fortunately, it works with HA, so the note on the integration page is not (completely) correct.

Just had to provide the local-ip to the integration, nothing else.

The note at the top of the page is talking about the C version,

This affects units fitted with the BRP069C4x wifi adapter

you have the B version about which it says in the supported hardware section:

The new version of WiFi Controller Unit BRP069Bxx is also confirmed to work,

Unless I am missing something?

Can you point out where it is incorrect so I can edit it?

I bumped into this thread, looking for a solution. I tried this one, but my devices don’t appear. Looks like an issue with the HACS integration, saw an issue logged in GitHub.
So as far as I can see and found out, I have no way to connect to my Daikin (C module) right now, nor local, nor cloud. Hopefully Daikin does something about it…

I have a - maybe stupid - question on this:

“We at Daikin Belgium and also Daikin Europe believe that there should be a local API for connection with home automation systems such as HA. Unfortunately Japan is a little more closed and they don’t agree.”

Wouldn’t DAIKIN need to make their API open to their end customers by the forthcoming EU Data Act?

Have you tried both integrations? There is a second one that someone worked on as a fork of the original. It is discussed in the Github repo.
