The new graphs introduced in 2025.2 look nice.
But I have a couple of sensors which report about each 1…2 seconds. When i open the default chart (just click on the entity history button), then it’s veery slow, and if I try to click… 8t’s freezing. The same on the mobile…
I can make a video if it is helpful.
Give these sensors a valid state_class. Then they will generate long term statistics and the pop-up cards will display 5 minute interval statistics data instead of the 1-2 second interval state data, which will load a lot quicker.
Thanks for the hint, I’m trying now. Indeed the 2 sensors I was mentioning are from esphome devices and I did NOT have state_class. I’ve added now state_class = measurement and … I wait until tomorrow (to have ~24hours) to check the results and I’ll confirm here
