Post 2026.3 update - Mushroom update card "Picture entity" not displaying

Configuration Frontend

Hello,

I have updated to HA core 2026.3 all looks reasonable except for the Mushroom Update card.

This is where I can’t get the entity picture to be display even though it has been selected correctly in the card.

I have looked at the new local brands integration documentation (for the entity picture - Icon / Logo) but it doesn’t help with my problem.

I think this could be down to a missing token issue but I’m not sure.

For example, looking at the attributes of the “update.home_assistant_core_update” entity via developer tools / status…

I can see the path for the entity picture which seems correct.

But this is where I can see that there is no token passed at the end of the “picture entity” URL path…

The problem is I don’t know how to address and where fix this, or change the requirements as stated in the link below.

This could be a problem or bug related the Mushroom Update card only as I can choose the entity picture in the native Tile card successfully.

Any guidance or solution how to resolve this would be greatly appreciated ?

I have a post about it too.
The path is in the updat entity, but if you go to the path on the web site, then you get an error 403.
It is not the mushroom cards, but the actually core, supervisor and so on th are missing the icons files.

Thank you for your feedback… :ok_hand:t2:

it’s so difficult to determine where the issue lay, hence the post.

I guess we have to wait for an update…

Sorry, perhaps I am missing smth, but see no issues with entity_pictures:

These entities have differently defined urls in “entity_picture” (and thus differently stored images):

Hi,

Thanks for your time and reply…

Yes I agree as stated lower down in my initial post that I can choose the picture entity for the same entity -

“update.home_assistant_core_update”

in the native “Tile card” successfully however not in the mushroom update card as depicted in my first post.

Hence It may be a Mushroom update card bug issue for that card only…

The picture entity is broken for all of my update entities using the Mushroom update card.

I need to verify this before placing a bug report with the mushroom card as this issue occured instantly post the HA Core 2026.3 update.

I noticed the difference between the two cards in the web inspector is that the Tile card had a token number passed to it at the end of the URL where the mushroom card did not. I believe that this is the API token mechanism required to be able to display the entity picture.

However that is the limit of my findings.

I use the entity_picture attribute in the update entities for my update dashboard and all the other ones work.
It is only the ones for the OHP products that fail and if I try to follow the url manually, then it will fail for those too, where as all the others work.

I am using a template for ALL update entities, so I can not just switch to a picture entity for some of them.
