Entity number precision acting weird after upgrade

[agroszer (AdamG)]

Hi,
Upgraded HASS from 2024.12 to 2025.8, some sensor values display went crazy despite precision set to a single digit.
For example 2 calculated helpers, sensor.temp_avg_mb2 is fine sensor.hum_avg_mb3 is not.

I have also sensors acting as such

Tried settings precision to default/custom 99.9 to no avail…

Also weird that sensor readings seem to be all 99.9 precision

what’s wrong?

What card is that?

See the 2025.7 release notes topic. 2025.7: That's the question - #11 by karwosts

If it is a template sensor you can do this: 2025.7: That's the question - #58 by abmantis

config is like:

Mindbogging is that some work some not, no idea why.

Sounds like multiple-entity-row makes my life miserable, but why randomly?

[tom_l]

@agroszer

no idea why.

I gave you two links that explain why.

[agroszer (AdamG)]

Looks like multiple-entity-row 's format: precision1 was the solution.

Thank you

Still stuck with this problem, I know I can use round=true or with a number, and yes I know I can set a default precision, but in some cases all this will not work, example with a mini-graph card:

type: custom:button-card
aspect_ratio: 1/1
icon: mdi:home
entity: sensor.t_huiskamer
name: huiskamer
size: 30%
custom_fields:
  graph:
    card:
      type: custom:mini-graph-card
      entities:
        - sensor.t_huiskamer
      show:
        icon: false
        name: false
        state: false
      line_width: 5
  hu: |
    [[[
      return `<ha-icon
      icon="mdi:water-percent:"
      style="width:14px;color: skyblue;">
      </ha-icon><span style="color: var(--text-color-sensor);">${states['sensor.h_huiskamer'].state}%</span>`
    ]]]
  temp: |
    [[[
      return `<ha-icon
      icon="mdi:thermometer:"
      style="width:14px;color:var(--accent-color);">
      </ha-icon><span>${entity.state}°C</span>`
    ]]]
styles:
  custom_fields:
    graph:
      - overflow: unset
  card:
    - overflow: unset
    - width: 120px
    - height: 110px
    - font-size: 12px
  grid:
    - grid-template-areas: "\"n i\" \"temp hu\" \"graph graph\""
    - grid-template-columns: 50% 50%
    - grid-template-rows: 1fr 1fr 1fr
    - overflow: unset
  name:
    - font-size: 12px
    - color: rgb(107,148,237)
  state:
    - font-size: 10px
    - color: rgb(107,148,237)

@jayjay

but in some cases all this will not work, example with a mini-graph card:

Then you need to report that to the developer of the third party card.

Thank you Tom, had not thought about this, cause it was in so many different cards and and representations of values, many of which I could repair with a simple round statement in the retrieval of the entity.state or value expression.

But you see no other option to adapt the code line:

 </ha-icon><span>${entity.state}°C</span>`

in another way? Cause as said there are more cards affected like this one!

And it looks terrible, I disabled several pages from my front end to not see all of these.
