There are many conceivable ways to map 30edo onto the onto the Lumatone keyboard. However, it has 6 mutually-exclusive rings of fifths, so the Standard Lumatone mapping for Pythagorean is not one of them. Many other mappings will also fail to cover the whole gamut.
Antidiatonic
The closest thing to a diatonic scale is using the bc val, which is a near optimal tuning for Mavila temperament.

If you want to concentrate on the more xenharmonic consonances available, the Lovecraft mapping is about as good as you can get.

Bryan Deister's mapping
Bryan Deister has used a layout for 30edo that was inspired by the layout for 29edo (rather than being made for any specific temperament), as demonstrated in minuet in 30edo (2025). The right-moving generator is a somewhat flat Pythagorean whole tone (~9/8, 5\30; and in the video, the row segments that include note 0 are colored solid red). The up-moving generator is a somewhat flat tridecimal supraminor second (~14/13, 3\30); neither would be able access the full gamut on its own, but together they cover the full gamut with a generous allotment of repeated notes (indicating that if this layout was to represent a particular temperament, that would have to be a rank-3 temperament if having an octave period, or a rank-2 temperament dividing the octave into multiple periods). The range is a bit under five octaves, with octaves slanting up (while wrapping around) at the same angle as the right-moving generator.
