Sensor de calidad del aire conectado a luftdaten.info ,Parte IV – Integrar en HA

Buenas , en estas líneas vamos a conectar nuestro sensor de calidad del aire a nuestro Home Assistant , lo primero crearemos un sensor para saber si esta conectado a nuestra red mediante un sensor ping.

- platform: ping 
  host: 192.168.1.26
  name: ping_luftdaten
  count: 5
  scan_interval: 300

Los datos los podemos extraer de varias formas , una de ellas es mediante el fichero data.json , para ello usaremos la integración local_luftdaten mediante HACS o directamente de la pagina https://github.com/lichtteil/local_luftdaten , también crearemos un sensor para traducir de hectopascales a milibares.

- platform: local_luftdaten
  host: 192.168.1.26
  name: estacion_luftdaten
  monitored_conditions:
    - SDS_P1
    - SDS_P2
    - BME280_temperature
    - BME280_humidity
    - BME280_pressure
    - signal  

- platform: template
  sensors:
    estacion_luftdaten_presion:
      friendly_name: 'Presión'
      value_template: >
        {{(states('sensor.estacion_luftdaten_pressure') | float / 100) | round(1)}}
      unit_of_measurement: 'mBar'

Crearemos un par de sensores para que nos indiquen la calidad del aire medido.

- platform: template
  sensors:
    # Air Quality Index = (PM10 mean over 1 day / 50) * 100
    air_quality_pm10:
      friendly_name: 'Air Quality PM 10'
      value_template: >-
        {%if ((states.sensor.home_assistant_pm_10_concentration_mean.state | float) * 2.0) <= 33 %}Muy buena
        {% elif ((states.sensor.home_assistant_pm_10_concentration_mean.state | float) * 2.0) <= 66 | float > 33 %}Buena
        {% elif ((states.sensor.home_assistant_pm_10_concentration_mean.state | float) * 2.0) <= 99 | float > 66 %}Regular
        {% elif ((states.sensor.home_assistant_pm_10_concentration_mean.state | float) * 2.0) <= 149 | float > 99 %}Mala
        {% elif ((states.sensor.home_assistant_pm_10_concentration_mean.state | float) * 2.0) <= 200 | float > 149 %}Muy mala
        {% elif ((states.sensor.home_assistant_pm_10_concentration_mean.state | float) * 2.0) > 200 %}Peligrosa
        {%- endif %}
      entity_id: sensor.home_assistant_pm_10_concentration_mean
    # Air Quality Index = (PM2.5 mean over 1 day / 25) * 100
    air_quality_pm25:
      friendly_name: 'Air Quality PM 2.5'
      value_template: >-
        {%if ((states.sensor.home_assistant_pm_2_5_concentration_mean.state | float) * 4.0) <= 33 %}Muy buena
        {% elif ((states.sensor.home_assistant_pm_2_5_concentration_mean.state | float) * 4.0) <= 66 | float > 33 %}Buena
        {% elif ((states.sensor.home_assistant_pm_2_5_concentration_mean.state | float) * 4.0) <= 99 | float > 66 %}Regular
        {% elif ((states.sensor.home_assistant_pm_2_5_concentration_mean.state | float) * 4.0) <= 149 | float > 99 %}Mala
        {% elif ((states.sensor.home_assistant_pm_2_5_concentration_mean.state | float) * 4.0) <= 200 | float > 149 %}Muy mala
        {% elif ((states.sensor.home_assistant_pm_2_5_concentration_mean.state | float) * 4.0) > 200 %}Peligrosa
        {%- endif %}
      entity_id: sensor.home_assistant_pm_2_5_concentration_mean  

Creamos un sensor que nos indicara la versión del software del sensor

- platform: rest
  name: Software Version
  entity_namespace: luftdaten
  resource: http://192.168.1.26/data.json
  method: GET
  force_update: true
  scan_interval: 600
  value_template: '{{ value_json["software_version"] }}'     

Ya habíamos visto como integrarlo en influxdb , ahora es el momento de poder extraer los datos que previamente vamos guardando en influxdb y trabajar con ellos y realizar las lectura promedio.

- platform: influxdb
