For those of you that want the log file back after updating to 2025.11, you can use this integration.
Just keep in mind that it will not capture some lines when HA starts up. It should start pretty early it just may not capture all the debug logs about custom integrations.
Iām guessing this keeps the new log saving system intact and simply copies the data to a separate (like previously) log file?
It adds the logging handle back. So itās essentially the same as before, just a delayed startup because it loads it as an integration instead of loading in the bootstrap.
If this ends up being popular, Iāll see if I can load it faster.
Installed! Thanks!
Is it installable without HACS?
Yes, follow the directions in the repo.
Iām not a programmer, so my question could be stupid:
Could this module be modified to send all events to an external syslog server instead of a file?
You could modify it but it would be very risky. I would not do it. I think youād be better off looking at another service to do that.
The risk is related to logger and how it behaves when it cannot access a file because of a network dropout.
The custom integration works fine, thanks @petro. I use the log-viewer addon to see the logs, however the ānewā log files dosenāt load there. Is it possible to view the log fies with a web viewer?
You have to reload the addon after startup most likely. The addon only looks for the file
Not sure if this is the right place butā¦
Iām not overly concerned about ālosingā the logs but would like to be able to know the size of the file.
I use it to show me if something is going badly 
What is the location of the āactualā log file and can I interrogate it?
Thatās just it itās not there anymore and you cannot unless you put it back.
I also spent two hours last night trying to hit it from the HA api and that endpoint doesnāt seem to work anymore (and I would think redirecting REST to the internal storage would bee the natural alternativeā¦) with or without the file in place. It just 404ās. The only thing Iāve been able to do to hit it programattially is put it back with Petros solution and then command line sensor itā¦
This one id REALLY like to thump whomever did NOT think this one throughā¦Absolutely boneheadded decisionā¦
You have to install it.
Iāve changed my mind.
I really miss the logs being accessible outside of HA (in my config folder)
Given petro created this in āno timeā after the HA version release (without in any way wishing to denigrate the effort you put in) surely this could have been added as an option. It really is this kind of small but far reaching decision that I think is often a blot on the otherwise impeccable copybook of the HA āleadershipā.
I am using that custom integration and i am seeing it creates an home-assistant.log, an home-assistant.log_1 and an home-assistant.log_old. Is this behaviour correct?
The integration only creates .1 and .log. The other file is created by core
Thanks, but why the core creates that file if it doesnāt create a log file?
They never pulled out the rest of the plumbing. You get the file to go back the system starts working like it used to.
Because thisā¦
It did it before so it does it again.
Which is yet another indicator to me they should not have done it in the first place.
