Display Precision not honored after 2025.7.0 | Home Assistant | Page 1

I am finding that the set Display Precision for a bunch of my Temperature and Humidity sensors is no longer being honored in the Front End.

#

Here ia the code for the bottom right button, sensor.env_master_ambient_humidity has an accuracy_decimals: 1 in ESPHome for the bme680 and the front end has a Display Precision of 1 decimal place. Changing it to 2 or 0 is no longer honored by v2025.7.0

entity: sensor.env_master_ambient_temp

  [[[ return states['sensor.env_master_ambient_humidity'].state + " %" ]]]```

It's up to the custom card to handle that.

#

You're just telling the template to print the state, which has nothing to do with display_precision

#

is there a way to round() it in the return states?

#

The source sensor has an accuracy_decimals: 1, so how can it have 20-15 places of accuracy?

craggy bobcat Jul 2, 2025, 7:03 PM

#

accuracy_decimals was changed to set the display_precision

#

not the raw state

#

But if the source sensor in ESPHome has of accuracy_decimals: 1 how can the state be 39.564338684082?

not the raw state

#

So what changed in 2025.7.0 that causes this and is there a way to fix it?

#

Is there a way to format the display on the [[[ return states['sensor.env_master_ambient_humidity'].state + " %" ]]]

craggy bobcat Jul 2, 2025, 7:12 PM

#

I'm sure there must be. That's just javascript right?

orchid thistle Jul 2, 2025, 7:12 PM

#

I am not sure to be honest

craggy bobcat Jul 2, 2025, 7:13 PM

#

guessing but maybe try this:

  [[[ return Number(states['sensor.env_master_ambient_humidity'].state).toFixed(2) + " %" ]]]

#

Nice, that works! Is there a guide for what other options are available? And that is just Java, thought it was Jinja or something like that

craggy bobcat Jul 2, 2025, 7:16 PM

#

Jinja is for core templates: {{ }}

#

That thing in custom button card is not a core template but just evaluates arbitrary javascript in the browser.

#

The odd part is this was changed in ESPHome 2025.6.2, but broke in Core 2025.7.0. Or was it that Core 2025.7.0 implemented the ESPHome 2025.6.2 change?

craggy bobcat Jul 2, 2025, 7:19 PM

#

I don't know what you mean it was changed in ESPHome. That pull request is a home-assistant/core pull.

orchid thistle Jul 2, 2025, 7:22 PM

#

Gotcha, I think I got crossed up looking at core change you sent and clicked the link to the Implemente HA suggested_display_precision Issue

#

Seems like if I set accuracy_decimals: 1 in the ESPHome config that is what it should send to HA
