Aqara D1 Smart Wall Switch (1-Key)

The Aqara D1 Smart Wall Switch is a mains-wired single-rocker wall switch for smart control of a lighting circuit. This catalog entry represents the one-button D1 family and the marketplace source contains both wiring versions: a no-neutral version and a with-neutral version. Aqara's device documentation identifies these as lumi.switch.b1lacn02 (no neutral) and lumi.switch.b1nacn02 (with neutral). Choose the version that matches the wiring available in the wall box; the two versions should not be treated as electrically interchangeable.

The switch communicates as a Zigbee smart-home device and is intended to be paired through a compatible gateway. Mi Home device documentation for the D1 family describes setup from the Mi Home client through a Xiaomi multi-function gateway or an Aqara air-conditioning companion, so Mi Home support is credible for these China-market D1 models, although the exact device list can depend on gateway and app region.

This is the wired wall-switch product rather than the separate battery-powered Aqara wireless remote switch. Once installed, it can switch the connected circuit locally from the rocker and expose switch control and automation actions through the paired smart-home system. Because the source offer spans both neutral and no-neutral versions, verify the selected SKU and household wiring before installation. Mains wiring should be handled according to local electrical requirements, preferably by a qualified installer. The switch is best suited to users who want to retain familiar physical wall control while adding remote switching and scene automation through an existing compatible smart-home gateway.
