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 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 ?
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.
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 ?
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.
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.
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.
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…
“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?
