Daikin AC Integration BRP069C4x

Making the Cloud API open != local API
See 🚀 Exciting News: Announcing Daikin Europe Developer Portal! 🚀 · Issue #182 · rospogrigio/daikin_residential · GitHub

Rate Limitation: To continue offering the Onecta API for free to all our customers a default rate limitation will be implemented.

What changes can already be prepared from your application?
Make your current application compatible with the upcoming rate-limitation of 150 calls/day. This will allow everyone to query at least every 15 minutes for temperature changes in their home of all their devices. Temperature variation in the home is often not so fast that a faster update rate is required.

So it seems the cloud API will be documented, which is nice. But a rate limit to get the device info every 15 minutes could be a bit troublesome…

@MassiPi
Have you documented your findings somewhere?
How did you connect the ESP to the S21 port? Do you have a schematic?

I have been putting together a guide on the ESP32 here:

Need Daikin Wifi? Use the Open-Source Faikin ESP32 Hardware instead of the official wifi Modules

Disclaimer - I have nothing to do with the Faikin project, but I do have five Daikin mini-splits, which were becoming a pain with Home Assistant. I am starting a new thread here, because visibility in the forum regarding the “Faikin” Wifi module for Daikin Mini-Split units does not seem to be well known. I did a search for “Faikin” and only a few posts showed up. I only stumbled across the Faikin after extensive googling looking for a way to make my Mini Splits work with Home Assistant again af…

i didn’t even use custom cables, just 4 dupont female-female

no schematics, but honestly it’s as easy as hell

So I’m back with an update and the solution that fixed my daikin connection problem…!!!

Daikin AC Integration BRP069C4x

I was blissfully unaware of Daikin turning to the dark side with the changes made to the api until my wifi had some issues and connectivity was down for a few hours. After fixing the wifi issues, I noticed that my HA integration with my Daikin AC was no longer working. The Daikin kept showing up as unavailable. (I have no clue why this only happened now) Tried the following: Rebooting HA Removing the Daikin integration and re-adding it by just supplying the ip address which ends up in a “Fail…

I left the issue unattended until I ran into another problem with my HA refusing to connect my first ESPHome device. It was showing up in discovered devices but I was unable to add it to HA.
So thinking back about the daikin issue that had been plaguing me I found that what the two problems shared was the wifi AP they were connected to. (Aruba)
So after digging into the logs I noticed that the Aruba APs also had a firewall active that was blocking traffic from my HA VM (in vlan 30) from sending certain traffic to the daikin (and esphome device) also on vlan 30 connected through wifi.
Since I didn’t need my Wifi AP to act as a firewall, the solution was to add this rule:

After waiting 5-10 minutes I was able to add the ESPHome device AND my long lost Daikin Airco unit!
No idea why I was unable to figure this out sooner maybe because I missed the fact that an Aruba AP somewhere in the process activated a firewall was left out of the realm of possibilities.

Hallo, ich versuche meine Daikin Klimaanlagen in Homeassistant zu Integrieren. Habe Daikin Residential Controller (ONECTA) homeassistant Installiert aber es funktioniert nicht.Kann jemand ein Rat für mich.

[sebl05 (Sebastiaan L.)]

I receive an unexpected error when trying to add the IP address in the host field to add my BRP069C4x (Daikin AC Unit). Can’t quite work out what I’m doing wrong. Any tips or tricks anyone?

[guzma]

I have the exactly same issue. Got four BRP069C4x units in EU, but for every IP unit I’ve tried to connect, I receive error message “Unexpected error”

Hello, i have daikin stylish code module wifi BRP069C4x
I try integrated in Homeassistant , but non find no work.
You have solve this problem?
Can help my solved?
Thx you

[guzma]

I figured it out! Official Daikin HA integration right now doesn’t support BRP069C4x module (read carefully the official page, it is mentioned there). So I downloaded Daikin Onecta via HACS, which works with this unit absolutely perfect!

@AYanguas did you or anybody else find a solution for the missing “Compressor Frequency” so far? I have just bought a new prefera (FTXA with BRP069C4x) unit, and I have the same problem, not getting the “Compressor Frequency” reading as sensor in HA through the Daikin Onecta integration. This is crucial to me, as so far the other units (FTXMs with BRP069A4x) were giving this information via the standard Daikin integration and some automations are based on the compressor frequency reading.
As I am able to see the older FTXMs from both integrations, I have noticed that the compressor frequency is delivered as sensor via the old integration but it is not delivered via the new Daikin Onecta integration, which means, the new units may be able to give this information also, but the integration is not picking it up (yet I hope). The new Onecta (or the old depreciated Daikin controller) mobile app never gave this info either for the old units, so none can be sure if the new units are actually capable to provide the compressor frequency info or not…
Any news or help will be highly appreciated.
