Prevent History page from preloading values

I may be alone in this, but most of the time I visit the history page it’s to investigate a single entity ID or a small set of entity IDs… and when I punch up https://<HA-IP>/history, I have to wait for the entire data set to load. It may only be a few seconds each occurrence, but if History could instead load with a blank Entity field rather than loading the state histories of every available entity ID, it would save me that time. Perhaps a “view all” button would allow the current function to be retained.

Agree on this, please do not forget to vote for your own request.

Thanks–first time here.

You can specifiy the entity you want the history about in the URL:


You can get the same from the UI when pressing Show more on the entity popup:


About multiple sensors, here’s something interesting I noticed by playing around. If you do this for multiple sensors:


It actually behaves as one would expect (showing the history of only the listed sensors), but only for a few seconds. Then it will switch to the full history view with all entities. Sounds like a bug / unintentional feature.

Yeah, I know about chasing down individual entity history from the popup. But this is cool:

I hadn’t tried that. It would be great to see a slick UI built for this… maybe something like the Lovelace UI for building an Entities card:

this would be so much more useful, mine takes ages and ages to load…

the history for multiple entities gets a vote from me too

I started writing a new history card that improves on the problems I feel the original history panel has:

  • Can be configured to display any combination of entities, in single or multiple graphs, in any order
  • Configurable colors and graph styles
  • Pixel perfect alignment of the horizontal time axes of all graphs (the lack of this is driving me nuts on the original history panel !)
  • Zooming and panning
  • Easy navigation on the history timeline with a more efficient date range picker and quick jumping by day or week
  • Much faster than the original history

Still lots of work though. Might put that up as a custom card if anyone is interested, once I consider it generally usable.

Hey, this thread got me motivated. I wrote a new history custom card that does pretty much everything this FR asks for (and much more). Let me know what you think !
