Screenshots
2 screenshots during a thunderstorm. One from weewx-wdc one from Belchertown.

I think I know what is happening.
I do not have 'rain' as data. Davis uses rain_in for that.

I'm attaching MQTT data for both the Davis WiFi Logger and the Davis WeatherLinkLive
The system weewx-wdc is installed on uses the WLL.

So, if I want the displayed card to show 'Rain' and the proper value, what should be in the skin.conf?

Current rain does not display though the Today's total on the card does update.

You mean the big '0.00 in' right above the 'Todays Total', right? Yeah, I also noticed this, this will very rarely go above 0.00. I looked through some code to understand what's happening here. So the skin uses this to render the stat tiles on the front page:

For eg. the outTemp: $current.outTemp, or the outHumidity: $current.outHumidity. For the rain, its the same: $current.rain. BUT: What is $current.rain? I assume in WeeWX terms its the rain observed during the last archive interval (just guessing) - but this is misleading and not very useful. The season skins also does not show this and only shows $day.rain.sum (the days total, see https://github.com/weewx/weewx/blob/master/skins/Seasons/current.inc#L32).

I would propose to remove the big '0.00 in' ($current.rain, since it does not make any useful sense) and instead combining the rain and rainRate tiles into one tile to show:

• Todays rain total
• current rain rate
• Days max rain rate

What do you think about this?

[gary-hammer]

I'd be happy with that, then I can just remove the rain rate tile.

Ok then, I will have a look as soon as I got time, will be included in the next release!

Thanks.
Look forward to the fix.
