Hide devices linked to user

Tags: #<Tag:0x00007f3f175470d8>

I have to users, that I’ve linked mobile phone devices to. These are tracked via my router & nmap.

The problem I have is that on the overview screen I see my two People/users and the 2 devices used to track these 2 users. I only want to be able to see the status of the users/people.

How can I hide the mobile phone devices but still use them to track my users/people?
