As I observed, `下に` can be read in two ways: `しも.に` and `した.に`.

  * As far as I know, `した.に` can be used to indicate objects spacial arrangement. 

  * How about `しも.に`? Dictionary says that it also means `down; below; downward` ([source](https://jisho.org/search/%E3%81%97%E3%82%82%E3%81%AB))

When to use each reading form?
