The Xiaomi Wireless Switch Bluetooth Version has been launched in China. The smart home gadget can trigger many Mijia devices as long as it is connected via Bluetooth 5.0 to a compatible mesh gateway device, such as the Xiao AI Speaker or the Xiaomi Multi-Mode Gateway 2. For example, you could use the button to trigger a single light or a whole smart scene; a movie night scene could include closing smart curtains, turning off lights and starting the TV.
Alternatively, you can use the Xiaomi Wireless Switch Bluetooth Version as a doorbell. You can set up three commands using click, double click and extended press controls. In fast mode, the gadget has a 350 ms response time and is expected to last for up to 50,000 presses. The device is powered by a CR2032 battery, providing an average of two years of life.
The switch measures 50 mm (~1.97-in) wide and 13 mm (~0.5-in) thick, with a white casing with anti-yellowing properties. When placed on a table, a silicone pad helps the gadget to stay in place. Or, you could use the accompanying 3M adhesive sticker to attach the device to the underside of a table or the wall. You can currently buy the Xiaomi Wireless Switch Bluetooth Version in China for 39 yuan (~US$5.50). It is unclear whether or when the gadget could be released in other markets.
