We can fix that too, get rid of it.
I know I am tapping in a bit late, but I wanted to add one thing that might help. If you look CLOSELY in the lower right hand corner of the phone shot below you can just hardly see the green check mark + gear which is normally up top. The code below removes the HE logo/Dashboard name, and relocates the top right stuff to bottom and sets the opacity .2.
If you set these dashes to only have access to given devices you can effectively 'lock down' a device to only the dashboards you provide links to. You can also set the opacity to .0 and you will not see the "settings stuff". It will still be clickable, but out sight, out mind and all. Enjoy.

Code
.dashboard div .header{position:fixed;bottom:-1em;right:1em;z-index:999;opacity:.2;zoom:.6;-moz-transform:scale(.6)}
.wrapper{height:100%;margin-top:0;padding-top:1em}
.dashBack,.dashName{display:none}
.dashboard div .header>.flex-auto.justify-end,.dashboard div .header>.flex-auto.justify-end>.flex{display:inline-block}
