Glance window not showing entity history

Bump from this unresolved Discord thread. Pasting here for easier read:

I’ve noticed that recently entities are not loading their history graph when you open their “more-info” panel.

The history exists though, if I go into the proper “History” tab and load that entitiy. That data is there just fine.

I don’t think I’ve changed anything about that. Was there any change about this in the last update? I cannot pinpoint when it started happening, but it was recent.

Also it’s not 100% of the time. I initially thought it was specific entities, but it’s not. Either it works for all, or it doesn’t.

A quick search didn’t find similar reports in Discord, so might be some issue of mine?

Everything looks OK here. What HA version are you using, and what’s the browser? This is the official Glance card, not something custom?

Latest HA 2025.5.3. Browser is Zen, but trying Chrome does the same.

This is not the Glance card or anything custom. It’s the “More info” window that opens when clicking on any entity.

Solved for me.

It was the history-explorer-card. I had enabled the override to show that graph isntead of the default one, and it broke in HA 2025.5.0.

There’s a PR to fix it but not merged yet.
