Asuswrt broke with 2025.12.2: Error setting up entry for asuswrt

Third party integrations
1

I upgraded HA from 2025.11.3 to 12.2 and looks like my asuswrt integration broke completely, showing as “failed to set up” in the Devices / Integrations page, and logging the following error on startup:

Traceback (most recent call last):

This is with an ASUS AiMesh setup running 3.0.0.6. No recent changes or reboots to the ASUS setup.

When I try to reload the HA asuswrt integration, I do see the following in my router’s logs:

Dec 8 19:13:24 HTTPD: [LOGIN][http][APP] success (<<HA's internal IP ADDRESS>>)

I did notice that 2025.12.2 did come with this change:

Bump asusrouter to 1.21.1 (@Vaskivskyi - #158192)

@Vaskivskyi any ideas on how to troubleshoot this one?

Thanks!

Looks like @Shuntfield also reported this here:

I am facing the same connectivity issue with my XT8 after upgrading to 2025.12.2

Hello, guys

I am really sorry for this issue on 2025.12.2. Unfortunately, unit tests for the backend library did not catch an important case of data formatting in the device API. The issue also did not happen on the physical device I have for testing

The fix was merged into the HA dev branch (Bump asusrouter to 1.21.3 by Vaskivskyi · Pull Request #158492 · home-assistant/core · GitHub) and will be released with 2025.12.3

If the same issue persists with 2025.12.3, please provide an error log. If your error log is showing issues with aioasuswrt library - this is an unrelated new issue in 2025.12.3 and should be checked here [asuswrt] 2025.12.3 Failed to set up: KeyError (aioasuswrt) · Issue #158822 · home-assistant/core

Both are related to the different 2025.12.3 issue with the second (SSH/Telnet) library aioasuswrt as I commented before

14

The original issue here was fixed in 2025.12.3. Any other issue should be reported properly separately

Thanks, fixed as of today
