System tile (old, not shown)
What it is
An old on/off tile for a system (from an earlier Project & Bridge layout). In this configurator version the code that draws it is never called, so it does not appear on any screen. Systems are now added with + Add a system on step 1.
What to enter
Nothing. It is not shown.
What it changes
Nothing, because it is not shown. (Its code would turn a system on or off for the project, which changes the hub settings and the app at the next deploy.)
If it goes wrong
If you need to add or remove a system, use the tiles under Systems in this home on step 1.
