Sorry for not being clear. The Crestron/Savant panels are not typically purchased separately as 1 item. They're installed by certified system integrators as part of a total package where they wire up the whole house (often new construction).

There have been rumblings and predictions that Apple could expand HomeKit's capabilities to eventually be a real alternative to Crestron/Savant. The previous iterations of HomePod and Apple TV acting as a home hub really wasn't a credible threat but a new product like HomeView is a step closer to the "professional smarthome automation" space. E.g. Apple offering a wall-mounted PoE option is evidence of that.
