REST 請教

mcdull

如果有json 回傳, 希望用 rest + template 讀取 Sensor, yaml 應怎寫?
YAML

sensor:
  - platform: rest
    name: 'airsensors'
    scan_interval: '300'
    resource: 'http://10.0.0.1/sensors'
    value_template: 'OK'
    json_attributes:
      - result
  - platform: template
    sensors:
       co2:
         value_template: '{{ states.sensor.airsensors.attributes["result"]["datas"]["co2"] }}'
         unit_of_measurement: 'ppm'


Json

   "rc":{
      "c":0,
      "p":"操作成功"
   },
   "result":[
      {

               "tips":"室外气象条件很好，适宜运动。"
            }
         ],
         "visible":1
      }
   ]
}
