Aqara E1 Smart Wall Switch (Wireless, 1-Key)

Aqara E1 Smart Wall Switch (Wireless, 1-Key) is the wireless one-key controller from the E1 wall-switch family. It is intended for scene and remote-control actions and does not need to be wired into a mains lighting circuit.

The linked SKUs explicitly identify “wireless 1 key” and Zigbee 3.0. That separates this version from E1 wall switches that physically switch loads with neutral or no-neutral wiring.

As a Zigbee device, the wireless E1 requires a compatible hub/gateway. The source listing advertises Mi Home support for this E1 family; however, newer Aqara regional ecosystems vary in whether E1 child devices are exposed in Mi Home, so server region and gateway firmware matter.

Use it where a physical button is useful for smart scenes—such as controlling a smart lamp, curtain or group of devices—without adding a wired switching circuit. The page does not publish a battery model or exact dimensions because the current dossier lacks a manufacturer code tying this SKU to one specific E1 hardware revision.

Wireless wall-style controllers can look very similar to mains switches in marketplace photos. Confirm that the selected SKU is the wireless key/scene-controller version and that the intended gateway exposes that child device in the selected app region. If the goal is to switch an ordinary wired lamp directly, choose a wired wall-switch variant instead; this wireless model sends automation commands only.
