weewx 4.8.0 PNG file issue

[Mks Mk]

we have installed (weewx-aqi), it calculates an air quality index.
the install and configuration were done and weewx just run fine with one issue we could not figured out the reason why.

in weewx Seasons (skin.conf) file the below lines were added:

    [[[dayaqi]]]
        data_binding = aqi_binding
        [[[[aqi_pm2_5]]]]


we can see the PNG file (aqi.png) was created in (/var/www/html/weewx) but it does not show on the weewx webpage, we have found out the link to this file is not added to the (index.html) during the webpage generate process.

we need your help on this issue.

You did not say which skin you are using.

Assuming it is "Seasons", you need to add "aqi" to option "plot_groups".

Look in skin.conf, in the [DisplayOptions] section, for option "plot_groups". It is a long list of plot_groups, such as barometer, tempdew, tempfeel, etc. Add "aqi" to the end.

we are using the Seasons skin and the "aqi" is there in the  "plot_groups" with the rest of other parameters under the "[DisplayOptions]".

the file "aqi.png" was made and it gets updated every 5 minutes but never showed up on the webpage. (((looking inside "index.html" file ....there is no link to "aqi.png")))

[Mks Mk]

the "weewx-aqi" is storing the data in different data base "aqi.sdb" and we are not sure if this does make different!

[Tom Keffer]

The file names should be "dayaqi.png", "weekaqi.png", "monthaqi.png", and "yearaqi.png". That is, not a simple "aqi.png".

Is that the case?

yes that is correct, the file name is  "dayaqi.png" 

[Tom Keffer]

I think you are correct that the problem is the extra database aqi.sdb that you are using.

The way the self-provisioning feature of Seasons works is that it checks the database to see if there is any data. By default, it is checking weewx.sdb. Unfortunately, there is no way to tell it to use a different database. 

I've created issue #803 to track.

In the meantime, you can force it to display the plot. I have not tested this, but go into the Seasons index template file index.tmpl (found at /etc/weewx/skins/Seasons/index.tmpl or /home/weewx/skins/Seasons/index.tmpl, depending on your install method) and replace this

    #for obs in $getobs($plot_name)
      #if $recent.check_for_data($obs)
        #set $show_plot = 1
      #end if
    #end for

with this

    #for obs in $getobs($plot_name)
      #if $recent.check_for_data($obs) or $plot_group == "aqi"
        #set $show_plot = 1
      #end if
    #end for

Let me know how that works out.

The file "index.html.tmpl" of weewx v4.8.0 contain slightly different lines than the one suggested but we went ahead and did these changes:

replaced this

    #for obs in $getobs($plot_name)
      #if getattr($recent, $obs).has_data

        #set $show_plot = 1
      #end if
    #end for

with this

    #for obs in $getobs($plot_name)
      #if getattr($recent, $obs).has_data or $plot_group == "aqi"

        #set $show_plot = 1
      #end if
    #end for

and it did work and the plot was shown on the webpage.

but how we can expand this temporary fix to include "aqi1" which belongs to another sensor and another data base "aqi1.sdb" 

we tried

#if getattr($recent, $obs).has_data or $plot_group == "aqi, aqi1"

#if getattr($recent, $obs).has_data or $plot_group == "aqi; aqi1"

#if getattr($recent, $obs).has_data or $plot_group == "aqi",  "aqi1"

none worked and weewx did not complain of these changes or gave any errors but refused to show the plot of both "dayaqi.png" and "dayaqi1.png"

[Mks Mk]

somehow this below line change fixed both plots

#if getattr($recent, $obs).has_data or $plot_group == "aqi" or $plot_group == "aqi1"

is it ok to keep or remove it?

thank you

[Tom Keffer]

This should do it:

      #if getattr($recent, $obs).has_data or $plot_group == "aqi" or $plot_group == "aqi1"
