Xiaomi E1 Smart Wall Switch (No Neutral, 1-Key)

Xiaomi E1 Smart Wall Switch (No Neutral, 1-Key) is the no-neutral 1-key configuration from the E1 wall-switch family. It is designed for a wired lighting circuit where a neutral conductor is not present at the switch box, while still adding Zigbee-based smart control.

The linked seller SKU explicitly identifies the E1 family, Zigbee 3.0, the no-neutral wiring mode and 1 key. It is therefore distinct from the E1 wireless scene controller and from neutral-wire versions.

The exact marketplace listing advertises Xiaomi Mi Home and HomeKit compatibility. As a Zigbee device, it requires a compatible gateway rather than connecting directly to the home Wi-Fi network. Device availability can depend on the gateway firmware and Mi Home server region, especially for China-market Aqara E1 hardware.

No electrical load rating is published here because the dossier does not provide an exact manufacturer model code for this 1-key variant and the seller listing covers several E1 configurations. Installation should follow the wiring diagram supplied with the exact unit.

Key count and neutral requirement are material hardware differences, not cosmetic options. Match the exact SKU to the existing wall-box wiring and intended number of lighting circuits before installation. The smart features also depend on a compatible Zigbee gateway and app region, so it is worth confirming both the electrical variant and the gateway pairing path before replacing a conventional wall switch.
