I was experimenting with this ruleset, I want to incorporate it in a bigger puzzle later.

Normal heyawake rules apply.

Additionally, orthogonally adjacent rooms (those which share at least one bold border) can't have the same number of shaded cells.

Heyawake rules:

• Shade some cells, that the remaining unshaded cells form a single orthogonally connected polyomino.
• Shaded cells must not be adjacent to each other orthogonally.
• Any straight (orthogonal) line of unshaded cells must not cross more than one border.
• Clues in rooms (orthogonally connected region divided by borders) show how many shaded cells there are in that room.
