This is probably covered, but thought I'd offer two tweaks I made to make my dashboard better for my iPhone 11 (but I did these tweaks on my PC because it was easier for me)
(1) Color for "ON" icons. I could not read the white fonts on the bright default yellow color, so I changed to a darker color for the device types I had on the dashboard:
(a) Display the dashboard, and hit the gear icon.
(b) From the list, select a device type used on your dashboard (outlet for me)
(c) Select the "Template" menu (upper right), and select "On"
(d) Select the "Background Color" box and enter the rgb values as 120,95,10
(e) So steps (b)-(d) for any other types you want to change.
This gives a nice dark bronze color and the white font is readable.
(2) I wanted to better fit the icons to the iPhone 11 screen (4 across and six down) so I ...
(a) Repeated 1(a) above, if needed
(b) Hit "Advanced" menu (upper right) which brings up something that looks like C++ code
(c) at about line 28, change colWidth to 98
(d) at the bottom of the code change rowHeight to 93
