If it is listed as supported by Faikin, you are probably good to go. There are multiple ways to hook them up.
They are also cheaper than the genuine Daikin Wifi modules.

When you speak about other ports as s21, which one ? Because I saw other ports but it is on other cards and other version, not on the same one.
There are 3 different connectors mentioned on the Github page:
S21X50AX35A
You can use any that are supported for your system, though most common to use is the S21 port.
I’ve received the faikin and seems to not work… even if it is connected to S21.
No AP wifi seen by my phone or computer from Faikin. No led on it too…
Seems to not have enough power ???
You may need a different port that provides more power, or check to be certain that you have the wiring correct.
OK, based on Wiring · revk/ESP32-Faikin Wiki · GitHub
I will check it but on the documentation, EKRS21 seems to be OK normally ???
While adapter cables can be sourced (from PAP to EH, such as the EKRS21), it is still possible to build your own.
Looks like it. I built my own cable for the S21 port as it was easiest - at least for me and at the time.
Hi All,
I have been using the Faikin boards for quite some time without any issues. I also disabled the on board cloud wifi modules.
Since Faikin does not report error codes, would it be a good idea to have both the on board and Faikin operating at the same time?
I’m only asking because I am a bit concerned of a firmware pushed by Daikin can change something that Faikin depends on.
Do you believe that the above would be possible please?
In my case, my Daikin’s no longer have access to the internet, and I do not apply firmware updates to them. I have a set that are still on the OEM wifi modules, but will be removing those. I personally see zero need for them to have any internet access - as designed, they operate without the need for internet connectivity.
Agreed.
I am only interested in the error codes as a Faikin does not support them (currently at least).
There is nothing else I need from the daikin cloud.
Installed the first Faikin today and was also confused with correctly configuring the Timezone I am living in on the Faikin module. On the internet I was unable to find anything useful about the latter either.
After some trials I found out how to correctly configure the timezone within the Faikin configuration (Faikin-S3-MINI-N4-R2: b3be82a+ 2024-03-08T15:03:39):
- Click on the link (info) next to “Timezone”.
- On the Timezone-info-page search for the country/city you are living in.
- As i.e. for “Vancouver” you’ll find on line 230:
{“name”:“Vancouver”, “tz”:“PST8PDT,M3.2.0,M11.1.0”}, - Copy the last block (PST8PDT,M3.2.0,M11.1.0) into the “Timezone”-text field on the referring Faikin configuration page (without the quotation marks!).
- Save.
Hope this helps other people confused with how to properly configure the timezone to use directly within the Faikin configuration.

Works suprisingly good. I’m very happy with it and just ordered a bunch more for all of our AC units.
I have two ceiling air conditioner unit with this kind of remote:
(BRC073A1)
On the pdf i saw the S21 port is where it should be connected. Does this mean i need to remove the wired thermostat in order to connect a Faikin board?
Thanks for the great job. Did you use a level shifter on the I/O data pins (5v → 3.3v)? From technical sheet ESP8266 is not tolerant to 5v. Thanks in advance!
Nope, not required
Still working fine since last year
Great! I’d like to have more information about the CN_WIR connector. I’ve googled a lot, with poor results. Do you know where can I study?
