@sean wow, thanks. That’s perfect. Just one point - I’ve it in top_center segment and the image is alligned to the left of that column. how to align it to center?

I had no idea, how it works, but I guess via this modul is possible to get every data from every site, right? So, If I’ll need to get from here the last table on the bottom, is there way, how to do it?

thanks, Zdeněk

I think MMM-Widget could solve this problem.
Install that module and adjust config like this;

{
          //disabled:true,
          module: "MMM-Widget",
          config: {
            widgets: [
              {
                position:"top_left",
                html:`
                < img src="" id="IMG" >
                < script >
                var draw = function(img) {
                  img.src = "http://portal.chmi.cz/files/portal/docs/meteo/rad/mobile/ra6_30min.gif?" + Date.now()
                }
                var img = document.getElementById("IMG")
                draw(img)
                setInterval(function() {
                  draw(img)
                }, 1000 * 60 * 10) // will be refreshed every 60*10 secs.
                < /script >
                `,
                width:"200px",
                height:"200px"
              }
            ]
          }
        },

(Remove space around side of < and >)

I think that problem is caused by image cache.
For performance, usual browser(and server) uses cache-control, so, your gif image would be cached.
The easy solution will be change your URL slightly, like this;

http://portal.chmi.cz/files/portal/docs/meteo/rad/mobile/ra6_30min.gif?SOME_RANDOM_SEED_VALUES

But all of iFrame modules are not supported this feature.
