Sensirion SPS30 via Tasmota missing device classes and units

[arnowelzel]

The problem

I use a Sensirion SPS30 connected to Tasmota and reporting values via MQTT.

In Tasmota the SPS30 reports four values for particle matter: PM 1.0, PM 2.5, PM 4.0, PM 10. All values are expressed as ug/m³.

However in Home Assistant, only PM 10 is correct as "particle matter". All other values don't use the same device class and therefore are only reported as numeric values.

The following partial JSON shows the issue - for PM10 HomeAssistant reports µg/m³ as unit_of_measurement and pm10 as device_class. However all other values are missing that.

The result is, that in the UI these values are only visualized as state and can not be used for graphing.

@arnowelzel please share what the sensor update from the tasmota device looks like. In the Tasmota console, type in status 8 and share the output here.

@emontnemery Here you go:

stat/tasmota_C04EDC/STATUS8 = {"StatusSNS":{"Time":"2024-03-05T19:25:48","SCD30":{"CarbonDioxide":693,"eCO2":662,"Temperature":22.9,"Humidity":35.8,"DewPoint":6.9},"SPS30":{"PM1_0":1.90,"PM2_5":2.01,"PM4_0":2.01,"PM10":2.01,"NCPM0_5":13.16,"NCPM1_0":15.14,"NCPM2_5":15.19,"NCPM4_0":15.19,"NCPM10":15.19,"TYPSIZ":0.45},"TempUnit":"C"}}

I think you missed the sensor. Ah you got 2 :) I got this: 19:57:20.851 MQT: stat/tasmota_5D42D3/STATUS8 = {"StatusSNS":{"Time":"2024-03-28T19:57:20","SPS30":{"PM1_0":1.41,"PM2_5":1.73,"PM4_0":1.93,"PM10":2.03,"NCPM0_5":8.99,"NCPM1_0":10.89,"NCPM2_5":11.18,"NCPM4_0":11.22,"NCPM10":11.22,"TYPSIZ":0.60}}}
