How to read boiler error codes (F.25) from Vaillant VC PL 186/3-5 using ebusd?

[gp3991]

Hi,

I’m using ebusd with my Vaillant VC PL 186/3-5 boiler and have it integrated with Home Assistant. Everything works fine, but I can’t see any sensor or entity showing the error codes.

From time to time, my boiler shows this F.25 error, and I’m trying to find the root cause. I’d like to monitor these faults directly through ebusd.

Is there a way to read or log such error codes using ebusd?
