Unlike common sensors that react only to movement, SwitchBot reliably detects that you are in the room even with minimal activity thanks to the combination of mmWave radar, a PIR sensor, and an ambient light sensor. This is especially useful in a bathroom, home office, bedroom, or reading nook—the light will no longer randomly turn off just because you haven’t moved for a while.
With a wide 120° field of view and a range of up to 8 m for motion (and up to 5 m for static presence), it covers a larger part of the room without complicated planning. The practical magnetic base allows placement on a wall or flat surfaces and lets you adjust the angle and detection zone for more precise automations.
For reliable real-world operation, it features AI self-learning to help filter interference (e.g., a fan or air conditioner) and reduce unwanted triggers. It supports fast local automations even without a hub (up to 2 scenarios), and with a SwitchBot Hub it can handle more advanced smart scenarios. Thanks to Matter support, you can easily integrate it into common smart home platforms, and data can stay local without being stored in the cloud.
