Describe the bug Load skin fail after update weewx version 4.6.0 but I kept my weew.conf file. I downgraded to previous version 4.5.1

[James-76]

Interesting - I just upgraded to 4.6.0 to see what would happen and it appears to be running fine on my website https://blisteringbarnacles.co.uk/

wget http://weewx.com/downloads/weewx-4.6.0.tar.gz
tar xvfz weewx-4.6.0.tar.gz
cd weewx-4.6.0
python3 ./setup.py build
sudo python3 ./setup.py install

/home/weewx# diff weewx.conf weewx.conf.20220208215340
26c26
< version = 4.6.0
---
> version = 4.5.1

I hate python debug as it seems to be terrible at giving useful information so I will admit I can't tell you why it is complaining.

Hi, thanks. The isue comes from graph.conf file because if I use default graph.conf.example it does not give an error. Add my graphs.conf.txt

[James-76]

After slowly deleting sections, and using wee_reports to test it, it was started complaining when I added the following section back in under [homepage].

I then commented out the [[[lighting_strike_count]]] section and then it started working.

This means that there is something about how you have defined lightning_strike_count into your setup or something has changed with the weewx code with how it is being worked out.

     [[llamps]]
    title = "Número i distància dels llamps"
        subtitle = "Podeu consultar més gràfics de llamps al següent <strong><a href="/graphs/?graph=llamps" style="color:#e5554e">enllaç</a></strong>"
        #time_length = year
        #aggregate_type = max
        #aggregate_interval = 86400 # 1 day
        #gapsize = 86400000
        type = column
    yAxis_label = ""
        [[[lightning_strike_count]]]
           name = "Número de llamps"
           stacking = normal
        [[[lightning_distance]]]
           name = "Distància llamps (km)"
           stacking = normal

[dtalens]

Thanks @James-76, if I remove [[lightning_strike_count]] from my graph.conf file it will work again. Just deleting it from the [homepage] section still failed, I had to remove it from other sections so that it doesn't give an error. Now the question would be why does this happen?

[James-76]

The error is saying that it is getting back '%' rather than an integer when looking up the StringFormats

Sounds like the obs_group is not possibly correctly defined for lighting_strike_count?

What have you defined in extensions.py for lighting_strike_count, and what happens when you search for that in belchertown/skin.conf?

eg here is my example for sunshineHours

# grep sunshine /home/weewx/bin/user/extensions.py
weewx.units.obs_group_dict['sunshineHours'] = 'group_radiation'

# grep group_radiation skin.conf
        group_radiation    = watt_per_meter_squared

root@pi:/home/weewx/skins/Belchertown# grep watt_per_meter_squared skin.conf
        group_radiation    = watt_per_meter_squared
        watt_per_meter_squared = %.0f
        watt_per_meter_squared = " W/m²"

As you can see watt_per_meter_squared is defined under [[StringFormats]] as the stringFormat for sunshineHours.

[James-76]

gjr80 has commented on weewx-user which is similar to what you are seeing https://groups.google.com/g/weewx-user/c/VfpSRxNQits

"I see now there have been some changes have been introduced in WeeWX v4.6.x to how default labelling and formatting of observation types is determined and it appears that group_energy/watt_hour may have fallen through the cracks. I think we can work around the issue in your case by adding some additional lines to user/extensions.py:

weewx.units.default_unit_format_dict['watt_hour'] = '%.1f' weewx.units.default_unit_label_dict['watt_hour'] = u' Wh'

Again you will need to restart WeeWX for the changes to take effect and hopefully the first report cycle should add you missing units/formatting.

Gary"

[dtalens]

I added this code to the extension.py file but it still fails:

import weewx.units
weewx.units.obs_group_dict['lightning_strike_count'] = 'group_count'
weewx.units.default_unit_format_dict['lightning_strike_count'] = '%d'
weewx.units.default_unit_label_dict['lightning_strike_count'] = ""
