I think the README tacitly says "redstone is not supported" since those blocks have multiple states:

  Note that blocks with multiple states, orientations, or interactive blocks require large amounts of specialized code to make them behave properly, which is way beyond the scope of this project. Some are supported, however:

  torches (all variants)
  slabs (all variants)
  stairs (non-connecting)
  rotated pillars, such as logs or basalt
  buttons (non-interactive)
  doors (including interaction)
  trapdoors (including interaction)
  beds

In particular, it seems buttons don't emit redstone signals.
