Sharing a single dashboard to an outside source to view only

I’m not sure where I should post this so admin please feel free to move to the correct category or let me know where I need to repost this.

I would like to share my Energy dashboard with my Sparky, but I obviously don’t want him to have access to the underlying code etc. So in effect a “camera” pointing at the page but with the ability to be able to click on the various buttons to also see the long term graphs and info.
As my Sparky doesn’t live with us this would need to be available externally via a URL or similar.
I know there is a Wallpanel card (which I’ll admit I haven’t tried yet) but based upon other posts that I’ve read this doesn’t look like it would do what I require and the removal of just a bit of the path exposes everything that’s inside HA.

Hoping someone can help.
Thanks

HA hardly have any user access control, so it is not possible.
You might hide the other stuff, but it is still accessible and you can not hide it that well.
