How to just show actual value in history chart?

The change to displaying 5 minute LTS data (long term statistics) rather than state data in the more info pop-up was introduced to speed up display of graphs on slower connections/hardware. Particularly for graphs with a lot of data. The 5 minute max/min/average is only 864 LTS data points for 24 hours. A 10 second updating sensor would be 8640 state data points to display.

You have two options to see the state data:

  1. click the “Show more” link in the pop-up card this will take you to the history panel where actual state data will be displayed. If you go back in time longer than your recorder purge_keep_days setting (10 days by default) this will revert to LTS data.

Or

  1. Remove the state_class from your sensor. This will prevent LTS (long term statistics) being collected for that sensor and the pop-up card will revert to showing state data.

NOTE: removing the state_class from energy sensors will prevent them from being able to be used with the energy dashboard.

You could also use a 3rd party graph card (e.g. apexcharts) to display the state data in your dashboard. Or use the 3rd party browser_mod custom component to make your own pop-up card replacements.
