Honeywell HPMA115S0 - json attributes help request

Configuration
1

Hi all. I’m new into Home Assistant. Just switching from Domoticz as I move house and decide to start from scratch in HA.
I have successfully set HA and communications through MQTT (mosquitto) for some testing sensors and switches but found an issue with pollution sensor connected to D1 mini with AFE firmware.
In MQTT topic I’m receiving

{‘PM25’:‘21’,‘PM10’:‘22’}

configuration.yaml

sensor weather:

  • platform: mqtt
    name: “Pollution”
    state_topic: “/weather/HPMA115S0/all”
    unit_of_measurement: “mg/m3”

this is what AFE firmware declare:
String JSON {PM25: Intiger, PM10: Intiger}

Could someone give me a hint of how the sesnor_attribute should look like, please?

I would like to collect separate value for each PM - 2.5 and 10

Many thanks.
Regards
Mario

Hi Mario,

AFE Firmware T6 v2

below is an example with Bme280, bh1750 and honeywell hpma115s0

assuming

  • mqtt topic for BH1750 sensor is : bh1750
  • mqtt topic for HPMA sensor is : hpma
  • mqtt topic for BME280 sensor is : bme

the firmware can handle BME680 and AS3935 sensor which additional params.

sensor:
  - platform: mqtt
    name: "Light level"
    state_topic: "bh1750"
    unit_of_measurement: "lux"
    value_template: '{{ value_json["illuminance"].value  }}'
  - platform: mqtt
    name: "PM2.5"
    state_topic: "hpma"
    value_template: '{{ value_json["PM25"].value  }}'
    unit_of_measurement: "μg/m3"
  - platform: mqtt
    name: "PM10"
    state_topic: "hpma"
    value_template: '{{ value_json["PM10"].value  }}'
    unit_of_measurement: "μg/m3"
  - platform: mqtt
    name: "Temp"
    state_topic: "bme"
    value_template: '{{ value_json["temperature"].value  }}'
    unit_of_measurement: "°C"
  - platform: mqtt
    name: "Humidity"
    state_topic: "bme"
    value_template: '{{ value_json["humidity"].value  }}'
    unit_of_measurement: "%"
  - platform: mqtt
    name: "Pressure"
    state_topic: "bme"
    value_template: '{{ value_json["pressure"].value  }}'
    unit_of_measurement: "hpa"
  - platform: mqtt
    name: "Relative pressure"
    state_topic: "bme"
    value_template: '{{ value_json["relativePressure"].value  }}'
    unit_of_measurement: "hpa"
  - platform: mqtt
    name: "Dew Point"
    state_topic: "bme"
    value_template: '{{ value_json["dewPoint"].value  }}'
    unit_of_measurement: "°"
  - platform: mqtt
    name: "Heat Index"
    state_topic: "bme"
    value_template: '{{ value_json["heatIndex"].value  }}'
    unit_of_measurement: "°"

Cheers!

Thanks Adrian :slightly_smiling_face:

After upgrading your firmware to 2.0 now is working perfectly. So that it looks like v 1.0 had a bug, isn’t it?
