iFrame card auto refresh

Configuration
5

You can add something like a meta refresh.

<meta http-equiv="refresh" content="5">

this header refresh page every 5 sec.

You need create custom web page in your <config-directory>/www/my_custom_web_page/index.html
For example:

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8">
    <meta http-equiv="refresh" content="5">
    <title>My custom web page</title>
  </head>
  <body>
   <iframe src="https://you-iframe-url"  frameborder="0"></iframe>
  </body>
</html>

And just use custom page like iframe

  • type: iframe
    url: “/local/my_custom_web_page/index.html”

It’s actually partly documented here: Webpage Card - Home Assistant
