SwitchBot Relay Switch 1 is a compact wired relay module designed to add smart control to existing electrical switches and devices without replacing wiring. Certified for Matter, it connects via Wi‑Fi and Bluetooth and can be managed through Apple Home, Alexa, Google Home or SmartThings. The module supports connection of SwitchBot Bluetooth devices and extends automation capabilities while fitting behind standard flush-mounted electrical boxes.

Advantages

The device provides smart control for lights, outlets, gates and other electrical loads without rewiring. Matter certification ensures interoperability with major smart home platforms. Built‑in Bluetooth repeating extends the range for other SwitchBot devices, and multiple switch modes (Toggle, Momentary, Detached, Edge) allow compatibility with different physical switch types. Safety features include a V0 fire‑rated enclosure and automatic overheat protection that disconnects power if temperature exceeds 100°C.

How to use

Install the SwitchBot Relay Switch 1 behind a flush‑mounted electrical box and connect it to the existing switch and power supply according to the provided wiring diagram. After powering the device, add it to your network using the SwitchBot app or Matter‑compatible controller, then configure desired switch mode (Toggle, Momentary, Detached or Edge) to match the physical switch. Pair up to ten SwitchBot Bluetooth devices if needed and assign automations, schedules or voice control via Apple Home, Alexa, Google Assistant or SmartThings. For safety, ensure correct wiring and follow local electrical regulations; installation by a qualified electrician is recommended if you are not experienced with electrical work.

Recommendations

Use the Relay Switch 1 for upgrading existing lights, sockets or garage doors where replacing wiring is impractical. Verify compatibility with your switch type and ensure the connected load does not exceed the listed maximum currents. For reliable Bluetooth and Wi‑Fi coverage in larger homes, position the module where it can act as a repeater and consider additional network extenders if necessary.
