Yes, it looks like a classic three-layer architecture. However, the pattern doesn't talk about the layers. Rather, it talks about ports and adapters.
HA expose interface to consume the inside component through a port and adapter is the middleware software component to interact with a port. Adapter can be in multiple technologies.

Thanks for suggesting a follow up on the comparison between HA and classical layered architecture.
