Cover does not open as per sun elevation and time control

[black-snake]

Hi @hvorragend,

I have version 2026.01.14 and I have a strange issue:

Yesterday morning and this morning I realized that some covers in my home did not open although they should have whereas others have opened.

It was past 08:40 o'clock in the morning today when the cover still did not open. There was no manual override or the like since midnight.

I already used the validator but could not find an deviation between the two cinfigurations. Also, the force variables haven't been true sine a few days and they are mutually exclusive (i.e. they can't be both true at the same time).

I did not change the configuration in the last days and it seemed to work fine with openening the covers.

I can only answer that if you show me the trace.

[black-snake]

Yeah, I understand. I will observe this tomorrow morning, too. Today's traces aren't available anymore because it currently only retains the last 5 or so and no traces from the morning are available anymore.

I will collect them tomorrow, hoping that it will occur there again...

Thanks for the quick reply, @hvorragend.

EDIT: @hvorragend Sorry! Forget about this one, I realized I pushed the button for the covers this morning accidentally. But I think I have another cover behaving wrongly. Will post that as soon as I verified.

Hi, finally, I see the issue again.

It happens sporadically only and it varies among the covers. It seems as if it is not necessarily always the same cover.

Please find attached the trace from this morning where the sun elevation got above -4.5° and the covers did not open. In my expectation, they should have opened.

@hvorragend Please find the configuration and traces below for the cover which was not touched.

Thanks.

@hvorragend Looking at the branch decision tree of @black-snake it seems like the issue is a misconfiguration of the shading parameters. The trace at 7.30 UTC time started the shading activity.

In my case the opening activity actually started but didn't trigger the opening of the cover. My trace:
trace automation.schlafzimmer_cover_control_automation_cca 2026-01-29T05_15_00.219550+00_00.json

I think it was cased because my cover was at 9% open (my shading position)? I use this in the evening via another automation to keep the air holes of my cover open, because I like to sleep with my window open. Need to confirm tomorrow.

I have 4 other covers with nearly the same configuration. Only difference is that I activated the "Evening Closing" automation from your blueprint on them which closes them completely to 0%.

Here an example:
trace automation.buro_cover_control_automation_cca 2026-01-29T05_15_00.244628+00_00.json
