Incompatible with current firmware

[MarkoBolt]

Seems like that the most recent firmware of the Daikin controller version: 436CC160000 is not compatible.

Model nr: BRP069A62

[tadasdanielius]

Thanks for bringing this up. Is there any errors or anything that might help us to make compatible with new version?

[MarkoBolt]

How can I assist with debugging?

Firmware: 436CC160000 Model: BRP069A62

I can see the following in Homeassistant:

Update: "Remove and add again" fixed it for me.

I have same error with following log. I checked the IP address and daikin own app gives different one (192.168.1.178) which may be (also) the issue, but could not figure how I could fix the IP address really. Adding new integration with the new IP does not work also.

This error originated from a custom integration.

by "adding new does not work" I mean that after giving IP next screen is and it does not add anything:

[tadasdanielius]

It might be useful to remove the old "integration" and try adding it again. Here are a few things to try:

1. Open your browser and go to http://your_daikin_ip/. This should result in an HTTP 500 error, but that's actually a good sign.

2. Try going to http://your_daikin_ip/mca. If you see something like this, then it's probably a good sign.

3. Restart the Daikin gateway, and immediately after it loads, try repeating the first step. The reason for this step is that a freshly booted device normally does not throw an HTTP 500 error but allows you to see some information and upload firmware. After some time, it starts to throw the 500 error.

I would recommend trying both the new and old addresses. Additionally, it would be helpful if you could log into your router and check the assigned address.

[MarkoBolt]

I have the same IP address and can find the unit after rebooting and see the following:

LAN adapter firmware:	1700390A
Smart grid:	disabled
IP address:	192.168.15.XXX
MAC address:
Serial number:
User interface SW:	v01.06.00
User interface EEPROM:	--
Hydro SW:	--

I did do some logging and got the following:

[tadasdanielius]

It seems like that daikin has closed local access to the gateway. Try to open in browser http://192.168.15.XXX/ and https://192.168.15.XXX/ Maybe they just changed the port or switched to SSL

[MarkoBolt]

http://192.168.15.XXX seems to connect to a white page in the browser.

[tadasdanielius]

Based from what you see is a good sign. There must be something with the configuration. I have 1700390A version as well. Seems to be working just fine. Have you tried to remove integration and add again? Any potential connection complexities between HA and Daikin gateway?

[MarkoBolt]

That worked for me. Remove and add again. So simple but weird that it is necessary.
