Aqara D1 No Neutral 1Key

The Aqara D1 No Neutral 1-Key is the single-rocker version of Aqara's D1 mains-wired smart wall switch. It is designed for wall boxes without a neutral conductor and directly controls one lighting circuit. Aqara's official developer device list identifies this configuration as lumi.switch.b1lacn02, and Aqara's D1 support documentation confirms that the switch uses a Zigbee communications module.

Unlike Aqara's separate battery-powered wireless remotes, this D1 model is installed in the wall and switches the connected load. The no-neutral design uses the live conductor and the load connection rather than requiring a neutral wire in the box. The D1 family supports local rocker operation as well as smart-home control and automation after pairing.

Aqara's official D1 support documentation describes adding the wall switch from the Mi Home client through a compatible Xiaomi multi-function gateway or Aqara air-conditioning companion. Together with the exact D1 model mapping, that makes Mi Home compatibility well supported for this China-market model, although availability can still depend on the gateway generation and Mi Home region/device list. The switch should therefore be treated as a hub-connected Zigbee subdevice rather than a standalone Wi-Fi switch.

For installation, confirm that the selected no-neutral version matches the wiring in the wall box and that the connected lamps meet the switch's electrical requirements. Because this is a mains-voltage device, installation should follow local electrical codes and be carried out by a qualified person where required. After pairing, the physical rocker continues to provide normal local control, so the lighting circuit remains straightforward to operate even when app control is not being used.
