HA 2025.7 breaks decimal point filtering

[bbs2web]

Entity card, with the following code, shows many decimal points:

  - entity: switch.sonoff_1001fc3bdd
    name: Extractor
    type: custom:multiple-entity-row
    secondary_info: last-changed
    show_state: false
    state_color: true
    entities:
      - entity: sensor.dht_bedroom_1_bathroom_temperature
        name: Temperature
      - entity: sensor.dht_bedroom_1_bathroom_humidity
        name: Humidity
      - entity: switch.sonoff_1001fc3bdd
        toggle: true
        name: false

The temperature and humidity entities themselves have relevant decimal point filters applied though:

This changed after upgrading Home Assistant to 2025.7

What it used to look like:

Used the work around detailed in the linked duplicate, not sure why this only bit me after upgrading to HA 2025.7.

This is a duplicate, so no point to keep this issue open. The card shows a raw value like most of custom cards. What changed in 2025.7 is a presentation of some ESP entities in HA.

I can confirm this issue, it appeared for me as well recently. Despite having rounding set on the entity, multiple-entity-row shows the full precision (e.g., 25.700000762939) instead of the rounded value. This behavior seems to have changed recently – previously the UI respected the rounding. I'm using this for ESPHome sensors in Home Assistant.

Happy to provide more details if needed!

my code:

`type: entities
title: Szoba
state_color: false
show_header_toggle: false
entities:

• type: divider
• entity: sensor.gyerekszoba_temperature_esphome
  type: custom:multiple-entity-row
  name: " "
  show_state: false
  entities:
  • entity: sensor.gyerekszoba_temperature_esphome
    name: Hőmérséklet
    styles:
    width: 60px
    text-align: middle
  • entity: sensor.gyerekszoba_humidity_esphome
    name: " "
    icon: mdi:water-percent
    show_state: false
    styles:
    width: 60px
    text-align: right
  • entity: sensor.gyerekszoba_humidity_esphome
    name: Páratartalom
    styles:
    width: 90px
    text-align: middle
    `

result:

I can confirm that the issue was resolved for me by adding
format:precision1
to the affected entities. After applying this change, the excessive decimal precision is no longer shown.

Came here in panic, thanks for the precision suggestion.

I also had to add this everywhere, because what used to be a single line with the value and unit, now gets wrapped to two lines.
