Product Description 【Lights On When You Enter, Off When You Leave】 Pair the SwitchBot mmWave Presence Sensor with the SwitchBot Bot for fully automated lighting — no rewiring, no renovation. The radar sensor detects your presence and the Bot physically presses your existing light switch. Walk in and the light turns on. Walk out and it shuts off after a customizable delay. 【mmWave Radar — Detects You Even When Still】 Unlike traditional PIR motion sensors, the mmWave radar sensor detects stationary people — whether you're reading, working at a desk, or sleeping. No more lights cutting out just because you haven't moved. Reliable presence detection, 24/7. 【SwitchBot Bot — Makes Any Existing Switch Smart】 The Bot attaches directly to your existing light switch, coffee maker, or any device with a physical button. It controls the switch mechanically via Bluetooth — no electrician, no rewiring needed. Compatible with toggle switches, rocker switches, and push buttons of all types. 【Save Energy Effortlessly — Never Leave the Lights On Again】 Left the hallway light on? Bathroom light running all night? Not anymore. The Presence Sensor reliably detects when a room is empty and the Bot switches the light off automatically. Cut your electricity bill without ever having to think about it. 【Wireless & Battery-Powered — Set Up in Minutes】 Both devices are completely wire-free. The Presence Sensor runs up to 2 years on a single battery charge; the Bot is powered by a CR2 battery. Attach with the included adhesive pad — no drilling, no tools required. Set up through the SwitchBot App in minutes. 【Wide Compatibility — Alexa, Google, Siri, SmartThings & Matter】 Bot supports: Alexa, Google Assistant, Siri Shortcuts, IFTTT, SmartThings, and LINE Clova (Hub required). Presence Sensor supports: Alexa, Google Assistant, IFTTT, SmartThings, and Matter (Hub required). Link both devices through the SwitchBot App and integrate them into your existing smart home setup. 【Note: Wi-Fi Remote Control Requires a SwitchBot Hub】 This set operates locally via Bluetooth. For Wi-Fi remote control — such as controlling devices away from home or using voice assistants — a SwitchBot Hub (sold separately) is required. The SwitchBot Bot also supports HomeKit via Matter with the Hub 2 (2nd Generation), allowing you to add it directly to Apple Home.
