Extended More-Info Card

A custom Home Assistant Lovelace card that provides a pixel-perfect replica of the native ha-dialog-header (close, history, settings, and kebab menu) along with the entity's default more-info controls, followed by any user-defined extra Lovelace cards.

Requires: browser_mod v2+
This card is designed exclusively to be used as the popup content inside a browser_mod more-info dialog override. It relies on the popup dialog context to render correctly and should not be used directly on a Lovelace dashboard.

browser_mod setup

Primary usage — popup_cards (recommended)

browser_mod's popup_cards feature intercepts the native more-info tap for specified entities and replaces it with your custom card. This is the primary intended use case for this card.

Add this to your configuration.yaml:

browser_mod:
  popup_cards:
    fan.bedroom_fan:
      type: custom:extended-more-info-card
      entity: fan.bedroom_fan     # must be specified here as well as in popup_cards key
      content:
        - type: button
          name: "5 min"
          tap_action:
            action: call-service
            service: script.fan_run_timer
            data:
              fan_entity: fan.bedroom_fan
              timer_entity: timer.fan_bedroom_timer
              duration: 300
        - type: button
          name: "15 min"
          tap_action:
            action: call-service
            service: script.fan_run_timer
            data:
              fan_entity: fan.bedroom_fan
              timer_entity: timer.fan_bedroom_timer
              duration: 900

Why is entity specified twice? browser_mod uses the top-level key (fan.bedroom_fan) to decide which entity tap to intercept, but strips that information before passing the card config to your custom element. The card therefore cannot infer the entity automatically — it must be explicitly provided in the card config as well. This is a known limitation of how browser_mod works, not a bug in this card.

For multiple entities, add a separate entry per entity:

browser_mod:
  popup_cards:
    fan.bedroom_fan:
      type: custom:extended-more-info-card
      entity: fan.bedroom_fan
      content:
        - type: button
          name: "30 min"
          tap_action:
            action: call-service
            service: script.fan_run_timer
            data:
              fan_entity: fan.bedroom_fan
              timer_entity: timer.fan_bedroom_timer
              duration: 1800
    fan.lounge_fan:
      type: custom:extended-more-info-card
      entity: fan.lounge_fan
      content:
        - type: button
          name: "30 min"
          tap_action:
            action: call-service
            service: script.fan_run_timer
            data:
              fan_entity: fan.lounge_fan
              timer_entity: timer.fan_lounge_timer
              duration: 1800

Secondary usage — browser_mod.popup via tap_action

You can also open the card explicitly via a card's tap_action:

type: tile
entity: fan.bedroom_fan
tap_action:
  action: fire-dom-event
  browser_mod:
    service: browser_mod.popup
    data:
      content:
        type: custom:extended-more-info-card
        entity: fan.bedroom_fan
        content:
          - type: button
            name: "30 min"
            tap_action:
              action: call-service
              service: script.fan_run_timer
              data:
                fan_entity: fan.bedroom_fan
                timer_entity: timer.fan_bedroom_timer
                duration: 1800
