Short answer.
No, it is currently not supported. But google around and try to find the protocol specification and I’ll try to integrate it. The app looks similar to previous models.
@fredrike I will try my best to see if I can get anything from google or maybe even Daikin. Besides that, is there anything else on my end I can do to extract some information?
You could try to intercept the communication between the app and your ac. I’m not sure how to do that though, you have to Google. There is usually quite good information on the whirlpool forum.
Hi everyone, I just have installed a brand new Daikin Perfera unit (https://www.daikin.eu/en_us/press-releases/form-meets-function-in-the-new-perfera-air-conditioner.html), and I cannot connect it to HA.
It does not use the usual Wifi adapter, but it has a wifi board built-in, which is supported by the following new app from Daikin, called Residential Controller: https://play.google.com/store/apps/details?id=com.daikineurope.online.controller&hl=it&gl=US
When I add the integration, it ends with “success”, but eventually creates a device called “Unnamed device”, containing only 2 non-functioning entities: the AC Inside Temperature sensor, and a climate.daikin_ac climate entity.
For the record, I also have another unit with the Wifi adapter, using the Daikin Controller app, that I was able to configure without any issues (it provides 6 entities, perfectly working).
Is there any chance the Perfera model will be supported in the future?
Is there any way I can help developing/debugging?
Thank you for letting me know, bye!

As a start you can try to find out if Daikin have a publicly available API for this new board.
Thank you for the quick answer!
So, it appears that it does have an API but it is not responding to the older commands, such as “common/basic_info”, “aircon/get_sensor_info” etc.
Now, if I try to access just the main URL of the device, the “older” (i.e., working with HA) replies with:

Now, how can we try to obtain the list of the callable API? I tried sniffing the traffic from the app to the device but with no luck.
Any suggestion? Shall we wait for Daikin or somebody to undisclose the APIs?
Thank you
If you cant find it by searching then you need to contact Daikin.
I tried to ask, let’s see if I can get an answer…

Is there any way the commands can be found by searching within the app files in the phone maybe? What do you think?
Mmmm bad news here… I searched the files of the Controller app and I found the usual API commands (get_control_info , etc…) in a file called base.vdex , but found nothing similar in the same file within the Residential Controller app… and no reply from Daikin in the meantime. Any other suggestion? 
Further update: the only open port on the device is the http one (80).
I installed an HTTP sniffer (HttpCanary) on my phone and analyzed the HTTP traffic of the app, and it just calls the Daikin Cloud APIs, which then will probably forward them to the unit. Calling similar URLs directly (I saw a /v1/info call) always ends in a “page not found” error (I also tried /info or /v1 …).
Probably, even if we could get the right URLs, we would need some kind of authentication.
Anything else I could try? Is it possible to sniff the traffic from the router to the device??
Bye
Could you test to extract the strings from the apk, I found the entrypoints from one of those.
@fredrike I have already tried (see post #42), but had no luck…is there some specific place you suggest I should search?
Some more info: today I tried to disconnect the WAN cable from my router, and to operate the Daikin device… well, the app showed an error “looks like your mobile is disconnected”, so maybe the new devices can only be operated via cloud connection…
Ok, so perhaps we need to use the cloud for this. What entrypoints on the cloud do you see?
What I did to reverse my Daikin was to look at the strings in the firmware (I think the firmware was included in the android apk).
Mmm not sure what you mean… how am I supposed to look for the cloud entrypoints?
Also, I searched the .vdex files and found nothing interesting, do you remember the name of the firmware files, by any chance?
Thank you
I have been trying to dismantle all the apks and running strings and searching in all binary files but I can’t seem to find any entrypoint, maybe you can try as well when you have some time? Maybe I’m missing something…
Thank you again!
I have one A/C of this.
Tomorrow I will try to do a mitm in order to get the protocol
