Smart homes often use AI, but not always. Voice assistants use machine learning to recognize speech and understand commands. Some cameras use AI to detect people, packages, or pets. Thermostats may learn schedules and adjust automatically. Many devices also use simple rules that do not rely on AI, like turning on lights at sunset or when motion is detected.

The mix depends on the product and the features you enable. AI can improve convenience, but it also adds privacy and data concerns. Choosing devices with clear controls lets you decide how much AI is involved in your home. If you prefer less automation, you can disable learning features and stick to basic schedules and manual controls for predictable results everyday.
