Hey experts I have 4 x Aircons that were all working with 9.X core using the Daikin AC integration. When the 10.0 upgrade occured I removed all 4 due to them not working and tried to add them again. I have tried with 10, 10.1 and 10.2 and still cant get these to work. HA identifies all 4 as discovered and identifies that teh appropriate integration is Daikin AC but trying to add them (with just the IP V4 address) fails. In the HA log the specific ERROR entry is:-
2025-10-12 01:04:11.801 ERROR (MainThread) [pydaikin.daikin_base] Exception in TaskGroup: Cannot connect to host 192.168.0.234:80 ssl:default [Connect call failed ('192.168.0.234', 80)]
I get the same message (exc IP ADDR) for all 4
At the same time as the 10.0 upgrade occured I had just had a sigenergy solar and battery system installed at home and it turns out that is very talkitive on the network and caused issues with other Daikin Alira X modules so it took some time to address that (moved the Sigenergy onto a different 192.168 class C) and to determine that this specific issue with the 4 heads was an upgrade related one.
If using a browser with a URL of http://192.168.0.234:80 (which is one of the BRP069B41 controllers) I get Error code: 403 HTTP_FORBIDDEN. (which I dont know enough to know if thats relevant or not.) According to the Daikin app on my phone the firmware version on all 4 of the controllers is 1.16.0
From a networking perspective my HA box is in the same class C as these 4 A/C's and my phone(via Wifi) and the daikin app on the phone has no issues controlling all 4 of these and 2 others that I control in HA using the "local Daikin" HACS integration. Im in AU and here they (the other 2) are called Alira X split systems. The 4 Im having trouble with are all Daikin CTXJ heads with a common outdoor unit.
I added the following to my configuration.yaml but didnt see anything extra of use in the log file
