Wi-Fi Smart Wall Switch Module for Alexa Voice Control

Built for the wiring you already have

• Control hardwired lights and fans

  The 10A max load switches lamps, ceiling fans and other wired appliances. Plugs cannot reach those fixtures, so this is where the module earns its place.

• Clear N/L terminal markings

  Input and output terminals are labeled N and L right on the housing. You check each connection against the marking before you close the box, so the install check stays simple.

• Wi-Fi with a status light

  The module runs on standard 802.11 b/g/n Wi-Fi. A small status button and a Wi-Fi symbol indicator show connection state at a glance.

Three ratings to check first

The switch you keep walking back to

The switch you keep walking back to

You get up to shut off a lamp you forgot, or you walk into a dark room you meant to light. Every manual switch keeps you tied to the wall, and the lamp stays on when you leave the house. Most smart home upgrades ask you to rip out working switches to fix that.

Smart control without new switches

The module is a bare Wi-Fi relay that mounts in the junction box behind the switch you own. Your plate, wiring and fixtures stay where they are. Unlike a wifi smart plug, it reaches a hardwired ceiling light or fan that has no outlet to plug into.

Done right, then left alone

Rated for a 10A maximum load on 90-250V at 50/60Hz, the module fits standard mains. Power off at the breaker and let a qualified electrician make the mains connections. Once it is on your network, the lamp or fan answers your phone and Alexa from the couch or from another city.
