NanoStation 5AC loco - Failed to deserialize AirOS data

[thefipster]

Hi there, I tried to integrate my fleet of NanoStation 5AC locos but there seems to be a serialization issue according to the logs.

Initial Warning

Hi @thefipster thanks for reporting - are you sure this is on Core 2025.8.1? I've (amongst presumably fixing the issue you have) added redaction of data which doesn't seem to be in place on your logging?

[thefipster]

Hi @CoMPaTech,
you’re right — that’s my mistake. I was still on an older version when I tested. I’ve now upgraded to Core 2025.8.1 but the error remains, but with different logs:

Thanks, looks like a regression on my side, I'll start a PR for 2025.8.2

Thanks for jumping on this so quickly! If you need any extra details, logs, or testing on my side to help with the PR for 2025.8.2, just let me know.

[CoMPaTech]

Hope we get over the first bumps with 2025.8 (in general) so we can continue adding stuff. Besides ensuring reauth/reconfig (prepped but waiting for non-SSL PR to pass) some other stuff is already planned and/or considered adding via https://github.com/orgs/home-assistant/discussions/624

[CoMPaTech]

Just checking in, does it work in 2025.8.2 for you?

I tested it this morning and it works beautiful. Have added multiple NanoStation 5AC loco without any issue. Thanks again for the quick reaction, really appreciated.
