Detect Device Source

Is there anyway to detect the device type being used and direct home assistant to a specific default page based on the device (mobile or desktop) ? Example, I have a set of simple pages (to make wife happy) that are formatted to work well on a mobile phone. Default page is a menu that leads to other cards with the individual entities. The menu page buttons change to red if any entity in the area is on, door is unlocked, furnace is running, etc. Makes for a quick and simple view on a mobile phone. However when I am at home and on a desktop, I want a page with much more detail to be my default page.

Is this lovelace? If yes, you can use Compact Custom Header and set a different start page for each user and also hide tabs per user and much more:

It is Lovelace and I am using cch. I had not considered doing it based on user but that’s a good idea and should work. Thanks
