template学习

1、统计楼层开灯数量

{%- set ns = namespace(total_lights_on=0) %}
{%- set rooms = floor_areas('yi_lou') %}
{%- for room in rooms %}
  {%- set entities = area_entities(room) %}
  {%- for entity in entities %}
    {%- if states[entity] is not none and states[entity].domain == 'light' and states[entity].state == 'on' %}
      {%- set ns.total_lights_on = ns.total_lights_on + 1 %}
    {%- endif %}
  {%- endfor %}
{%- endfor %}
{{ ns.total_lights_on }}

2、遍历楼层实体

{%- set rooms = floor_areas('yi_lou') %}
{%- for room in rooms %}
  Room: {{ room }}
  {%- set entities = area_entities(room) %}
  {%- for entity in entities %}
    Entity: {{ entity }} - State: {{ states[entity].state if states[entity] is not none else 'unknown' }}
  {%- endfor %}
{%- endfor %}
