I also did not get that to work, so i use
“MMM-iFrameReload”
That works without issues
Looks like this
{
disabled: false,
module: 'MMM-iFrameReload',
position: 'top_left',
//header: 'Graph',
config: {
url: "http://YourIP:3000/d/99SonoTEST/overview?orgId=1&kiosk",
width: "365px", // Optional. Default: 400px
height: "320px", // Optional. Default: 800px
refreshInterval: 300, //300= 5min . Default: 3600 = 1 hour
}
},
