Iframe card

I am trying to add an iframe with waze travel time component on my UI and i put in my config this:

- type: iframe
  url: https://embed.waze.com/it/iframe?zoom=5&lat=41.828570&lon=12.681369&pin=1&desc=1" width="300" height="400"

But i get this in the frontend:

The console gives me these errors:


Why no map is visible?

Local storage is per-domain. Since you’re using an iframe I think it looks like your HA domain is trying to access local storage it isn’t allowed to. Your security settings are probably blocking access.

Assuming this is from Chrome:

To be safer you might want to add an exception for your HA site only.

Can you show me how to add an exception?
Thanks…
