All done with the built in hubitat dashboard designer...
For the tablet I have just used an image I liked for the background. The life360 app for location info. For forecast I used theweather.com to build a widget and then used the link as a background image on a tile. The rest is mostly switches, dimmers and temp sensors. I have increased transparency on all tiles and used white/grey colours for off states or info only tiles and orange for on states. The two colour bulbs (bottom left and right) vary depending on white colour I have the bulb set to.
For phone dashboards I have created a few. One home page with most used functions and then dashboard links to each separate room. Each room then has all functions and a link back home.
Again, just used an image for the background, high transparency on the tiles and white/grey for off states and info and orange for on.
Some of the switches are routines, like the 'zzzz' are sleep routines which turn off all lights, tv, play rain sounds etc.
This covers most things i think. Let me know if you would like any further info.
