How to add weather forecast for the next few hours using Yahoo (or yr.no)? (I find only current day and next day)
$wf(cond,0,1)$ this are going to give you the conditions of 1 hour from now, changing the 1 for 2, change it for 2 hours from now, and so on. you can use the same with temp, icon, etc.
if I use text, is ok, but if I use Komponent (weather icon), nothing appear. Can be a language problem?
No, the komponent need to be created to use this codes, maybe you can find a kompo made to give hour forecast, but the majority are made to give day forecast, not hour forecast. I have one made with some linear weather icons, if I find it, I can upload it to my Google drive and you can download it to use and see if you like it.
