Re: [weewx-user] How to get the daily rain sum

[Invisible Man]

Ok, so I'm switching to templates, but I'm doing something wrong, because I 
can't get that rain sum. In my case it just prints 
"$since($hour=0).rain.sum.format("%.3f")" instead of showing the value.
How did you do it?
This is my `mastodon.txt.tmpl` (there are a few errors in my template e.g I 
shouldn't add ℃C etc, but nevermind) :

```

$day.outTemp.max)<br>

-Vitesse: $current.windSpeed (moyenne), $current.windGust (rafale)<br>
<br>
$current.dateTime.format("%d-%b-%Y %H:%M")
``

This is the generated mastodon.txt :
