weewx-aqi plugin

[miso k]

Hello,

I am trying to install weewx AQI plugin

https://github.com/jonathankoren/weewx-aqi

My weewx is 4.2.0 with extended database, pm10_0 and pm2_5 values.

I dont have weewx-purpleair, but custom sensor, which fills out the database through FilePile. So I modified the weewx.conf to:

# Options for extension 'aqi'

[AqiService]

    [[standard]]

        data_binding = aqi_binding

        standard = user.aqi.us.NowCast

    [[air_sensor]]

        data_binding = wx_binding

        usUnits = usUnits

        dateTime = dateTime

#        temp = extraTemp1

#        pressure = pressure

        pm2_5 = pm2_5

        pm10_0 = pm10_0

but I got the errors:

Dec 15 23:07:06 WeeWX /weewxd: AqiService: ValueError AQI calculation for pm2_5 on 1608069960 failed: NowCast AQI could not be calculated for the observations. Too many missing. Missing 2, which meets or exceeding the limit of 1

Dec 15 23:07:06 WeeWX /weewxd: AqiService: ValueError AQI calculation for pm10_0 on 1608069960 failed: NowCast AQI could not be calculated for the observations. Too many missing. Missing 2, which meets or exceeding the limit of 1

Dec 15 23:07:06 WeeWX /weewxd: AqiService: not storing record for dateTime 1608069960

what I have done wrong?

Thanks,
