ha里自定义传感器我想判断是昨天还是前天代码怎么写

bugensui

我想根据某个设备的属性值的日期，判断是昨天还是前天，请问代码怎么写

{{state_attr('sensor.electricity_95598','last_date')}}

value_template: "{% if  %}昨天{% elif %}前天{% else %}未知{% endif %}

复制代码

template:
  - sensor:
      - name: electricity_last_date_entity_jiandan
        unique_id: electricity_last_date_entity_jiandan
        state: >
          {% set now = as_timestamp(now()) %}
          {% set last_updated = as_timestamp(states('sensor.electricity_last_date_entity')) %}
          {% set diff = (now - last_updated) / 86400 %}
          {% if diff < 1 %}
            今天
          {% elif 1 <= diff < 2 %}
            昨天
          {% elif 2 <= diff < 3 %}
            前天
          {% elif 3 <= diff < 4 %}
            大前天
          {% else %}
            未知

谢谢大佬，按照你的方法搞定了

还有个问题，我想请教下为什么你这里要加 trigger，我直接自定义 sensor，也是可以显示的，其实就是根据1个实体的属性值，创建1个 sensor，为什么要加trigger，好像不加，也是可以的，不知道有什么区别

其实这里最好是不加，但以原来trigger创建过的sensor的状态为值，保证实时更新是前天还是大前天。

其它几项模板实体需要加上trigger，这样重启ha后，而docker中的服务没有更新时，那些模板的值不会变成不可用。
