That distinction is correct: homeostasis requires maintenance, and can typically be modeled as a result of some control process which optimizes (or at least satisfices) some cost over time. It can be often thought of as equilibrium, not on the system state space but on the space of system trajectories in time.
Attractors? The system might have several states that are good enough, and it might bounce between them?
Or the cat decides to shred the elastic...
