私は HASS 用のカスタム カードを作成するのが初めてなので、これは明白かもしれません。

私は基本的な時計カードを持っていて、レンダリング メソッドにコンソール メッセージを入れました。カードが表示されなくなっても、ログに書き込んでいるように見えますか? (つまり、別の lovelace ビューに移動しました)。

プロパティの変更をトリガーするためにを使用してsetTimeoutいます - ライフサイクルのある時点でタイムアウトを停止するつもりですか、それともライフサイクルに分解がありますか?

これが私のコードです:

  LitElement,
  html,
  customElement,
  property,
  CSSResult,
  TemplateResult,

import {
  HomeAssistant,
  hasConfigOrEntityChanged,
  hasAction,
  ActionHandlerEvent,
  handleAction,
  LovelaceCardEditor,
  getLovelace,
  LovelaceCard,
} from 'custom-card-helpers'; // This is a community maintained npm module with common helper functions/types
import { hass, provideHass } from "card-tools/src/hass";
import './editor';

import type { BoilerplateCardConfig } from './types';
import { actionHandler } from './action-handler-directive';
import { CARD_VERSION } from './const';
import { localize } from './localize/localize';

/* eslint no-console: 0 */
console.info(
  `%c  BOILERPLATE-CARD \n%c  ${localize('common.version')} ${CARD_VERSION}    `,
  'color: orange; font-weight: bold; background: black',
  'color: white; font-weight: bold; background: dimgray',
);

// This puts your card into the UI card picker dialog
