Automation issue since HA 2026.1.0

Configuration
1

Hello,

I have an automation issue,
yesterday I updated to 2026.1.0
and I found that since then the heating automation stopped running.
it wasn’t triggered at all.
So it was pretty warm when I came home.
maybe the trigger was missed?
so I ran the automation manually to stop everything

So I went to the traces

and see only 4
while my stored traces is set to 50

because I need to be able to investigate this.

where are my traces from before the update to 2026.1?

I checked a few other triggers,
as far as I can see they ran as expected, still the traces are gone

Updating HA causes a restart & a reload of all automations, which will wipe your automation traces from before the restart.

Check the 4 automation traces you have and see why the automation didn’t run till the end. Better yet, post your automation and the latest trace when it should have run. Someone will be able to tell you what happened.

that is good to know, but I hope some day a preserve option will appear.

Today the automation went smooth without any issues. But triggered manual.
it’s an 796 line automation(some parts can be optimized) but I don’t want to bother someone with that.

I actually think, Yesterday I had an incorrect REST sensor, now it’s removed,
the config showed still valid, but can that maybe break the triggers?
