Apple HomeKit works without cloud services. It is entirely local with your phone, mac, iPad etc directly interacting with the devices. I'm sure some of the individual devices from partners may leverage cloud services but I have yet to purchase a device that requires it. The only "cloud" aspect is if you want remote access to your devices an AppleTV can act as a proxy/gateway that let's you control your device from the internet rather than the local network. The eco-system is a hot mess at the moment but the basic design is well thought out.
