AQI Type Error in WeeWx 5.0 about weewx-aqi-xtype HOT 15 OPEN

This may be related to the fact my AQI sensor got so soaked in a rainstorm it shorted out, so no data is available, and the has_data issue previously raised.

The replacement parts are en route.

from weewx-aqi-xtype.

In python the min (and max) cannot have ’None’ in the list. The lists returned from get_series will need to be processed to remove these items.

from weewx-aqi-xtype.

How?

from weewx-aqi-xtype.

Sorry, that comment was meant for me. I did some initial triage and didn't want to lose it. Once I finish migrating to WeeWX I'll get on this.

from weewx-aqi-xtype.

Tell me if there is anything on this or your other project I can test.

The new air quality sensor's arrival from the manufacturer is imminent.

from weewx-aqi-xtype.

Latest commit removes any ‘None’ values prior to calculating NowCast AQI. Could you try it against real data?

Also, just curious, did this just start with upgrade to WeeWX V5? If so, any chance you also upgraded python?

Thanks

from weewx-aqi-xtype.

Sensor installed. No luck...keeps crashing with the error.

from weewx-aqi-xtype.

I’ll add some debug logging so we can see what the data really looks like.

from weewx-aqi-xtype.

Additional debug logging in latest commit. It will show the inputs to the NowCast calculations.

Also, did this just start with upgrade to WeeWX V5? If so, any chance you also upgraded python?

from weewx-aqi-xtype.

I'm not sure because of the gap caused by the hardware failure, but I never noticed it before the upgrade.

No recent python version changes...

1. Can you post the changes you had to make to seasons skin? Or even zip that directory.
2. Make sure you are running with the latest commit of weewx-aqi-xtype. Let me know if you need a release made.

Thanks

from weewx-aqi-xtype.

I am...and just added the types to observation stats.

Interesting, I’m seeing a blank line at

At this time, since debug =1 is broken in v5 it doesn’t really matter.
I’m trying to determine if it is base WeeWX or this xtype. I’ll let you know when I know more.

from weewx-aqi-xtype.

The error in seasons skin should be fixed in next WeeWX release. See 929 for details.
I hope the rss error is a side effect because that error has no information related to weewx-aqi-xtype.
