FYI I have a set of 4 dashboards designed for my Fire HD 8 wall-mounted tablets (rooted, running Lineage OS 14 and Fully Kiosk Browser), and then I have a dashboard designed for my phone. All done with the built-in dashboard app. The phone dashboard allows control of lights and Hubitat Safety Monitor, and viewing of my security cameras, but none of the weather displays I put on my tablets.
The tablet dashboards have dashboard links among themselves, but the phone does not. They are separate use cases for me. I just got the link to the dashboard for my phone and put a shortcut to just that one on my home screen.
