BRP069C8x firmware 2.3.0 detected via /common/basic_info but unsupported: /dsiot and /aircon control endpoints return 404

[eloimuns]

Description

I have a Daikin air conditioner equipped with a BRP069C8x Wi-Fi adapter.

The adapter was automatically updated through ONECTA to firmware 2.3.0 less than one month ago.

I am trying to add it to Home Assistant using the official Daikin AC integration, which relies on pydaikin. The device is reachable over the local network and responds successfully to some informational endpoints, but Home Assistant cannot create the device and reports:

Error creating device, 192.168.50.10 is not supported.

From the debug logs, pydaikin first tries the newer /dsiot/multireq API, which returns 404 Not Found. It then falls back to the legacy BRP069 API. The legacy API can read /common/basic_info, /common/get_remote_method and /aircon/get_datetime, but all climate-control and sensor endpoints under /aircon/... return 404 Not Found.

I would like to know whether BRP069C8x firmware 2.3.0 uses another local API that is not currently implemented in pydaikin, or whether this adapter/firmware is expected to be cloud-only.

Expected result

pydaikin should either:

1. Support the local API used by BRP069C8x firmware 2.3.0, if one exists; or
2. Detect this adapter/firmware combination and report clearly that it is not locally supported.

---

Actual result

The device is reachable and partially identified as a BRP069-compatible adapter, but setup fails because none of the currently attempted control APIs are available:

• /dsiot/multireq returns 404 Not Found
• Legacy /aircon/get_control_info returns 404 Not Found
• Legacy /aircon/get_sensor_info returns 404 Not Found
• Additional legacy status/control endpoints also return 404 Not Found

Home Assistant ultimately reports:

Error creating device, 192.168.50.10 is not supported.

---

Questions

1. Does the BRP069C8x with firmware 2.3.0 use another local API that is not currently implemented in pydaikin?
2. Is there any additional endpoint or diagnostic output I can provide to help investigate support for this adapter?
3. Is BRP069C8x firmware 2.3.0 expected to be local-control capable, or is it known to work only through ONECTA/cloud?

I am available to test additional requests against the adapter and provide further debug logs if required.

The only changelog from firmware 2.3.0: - Introducing firmware version 2.3.0 for BRP069C4x gateways, enhancing gateway security and cloud connectivity.

[fredrike]

I don't think BRP069C ever hast been supported, it doesn't support local control.

But you are right, we could probably detect this during init and report that in a better way to the user. Would be perfect if you could help pin down exactly what to look for.

[fredrike]

Hm, you actually get responses from some of the endpoints.. It would be interesting to see if there actually are a control endpoint that we have not discovered.

Here is a discussion for BRP069C home-assistant/core#174184

[fredrike]

I guess that this is the ones we should look for and raise a better response from:

GET /common/basic_info: type=aircon subtype=qa ver=2_3_0

[fredrike]

This is now addressed in PR #145.

What changed

pydaikin could already read /common/basic_info on your adapter (that's why it reported type=aircon, subtype=qa, ver=2_3_0, adp_kind=4), but since all /aircon/... control endpoints return 404, setup fell through to a generic Error creating device, <ip> is not supported. with no further detail.

The factory now detects this exact fingerprint (type=aircon + subtype=qa + firmware 2_3_*) and raises a clear message:

Error creating device, 192.168.50.10 is not supported: BRP069C8x with firmware 2.3.0 is not supported by pydaikin.

For other unsupported devices it now also includes whatever was identified from /common/basic_info (type, subtype, firmware, adp_kind), so the failure is no longer a blind "not supported".

Answers to your questions

1. Is there another local API? Not one that pydaikin currently implements. The /dsiot/multireq (firmware 2.8.0) API returns 404, and the legacy /aircon/* API is unavailable on this adapter/firmware.
2. Expected local-control capable? The BRP069C8x with firmware 2.3.x appears to be cloud/ONECTA-only from pydaikin's perspective — no supported local control API is exposed.
3. The PR adds regression tests using the exact responses from your report.

If you happen to find any working local control endpoint on the adapter, please share it — that would let us add proper support instead of just a clearer error.
