Smart WiFi Relay Switch: Voice, Timer & App Control

One relay, three ways to control it

• Schedule it and forget it

  Built-in timers and schedules switch the lamp on at 07:00 with no manual action. Set an off timer for a ceiling fan so it stops after you fall asleep. The schedule runs on the module, so the routine keeps working through your daily life.

• Control it with your voice

  The module works with Alexa, Google Home, and IFTTT through the eWeLink app. A standard plug-in device can use a smart plug with wifi, but a hardwired lamp or fan needs a relay on the circuit itself.

• Share it with the household

  Device control can be shared with other household members through the app. A partner, a parent, or a housemate can switch the living room lamp from their own phone, so nobody has to ask who left the fan on.

How it wires into an existing circuit

1. 1
   Cut the power

   Switch off the breaker for the circuit and confirm it is dead with a tester at the switch box.

2. 2
   Wire the input and output terminals

   Connect the supply to the input terminals and the lamp or fan lead to the output terminals behind the existing switch. Seat each wire fully and tighten the terminal.

3. 3
   Restore power and test the button

   Turn the breaker back on. Press the control button on the module and confirm the status LED responds.

4. 4
   Pair it in eWeLink

   Add the device in the eWeLink app on a 2.4GHz network. Send one manual on and off from your phone to confirm remote control works.

From the dark bedroom to a lamp that is already on

The dark morning

Every morning starts the same way: get up, feel along the wall for the switch, and stumble through a dark room. Lamps and ceiling fans on a standard wall switch give you no schedule and no remote. If you forget one running, you find out hours later.

A relay that fits the wall

The module sits behind an existing switch and takes the place of the manual connection. It handles loads up to 10A and 2200W at 100-240V AC, so a standard lamp or fan keeps working exactly as before. The fixture stays where it is, and the control moves to your phone and your voice.

Lamp on at 07:00

Set the schedule once in the eWeLink app and the lamp turns on at 07:00 without anyone touching a switch. Share access with a partner or family member and they can run the same device from their own phone.

From first wire to first schedule

1. First use
   Module wired and powered

   With the breaker off, the module connects behind the switch. Restore power and confirm the status LED responds to the control button.

2. Day 1
   Paired with the app

   Add the device in the eWeLink app on a 2.4GHz network. Test a manual on and off from your phone to confirm remote control works.

3. Week 1
   First schedule running

   Set the lamp to switch on at 07:00. Check the next morning that it turned on as scheduled and adjust the timing if needed.
