Product Information

Sonoff Basic R4 — Smart Switch

The Sonoff Basic R4 is a simple, affordable smart switch for beginners. Connect it to a light or appliance, and you can turn it on or off from your phone using the eWeLink app — from anywhere. It also supports eWeLink-Remote (a Sonoff feature that lets you control devices locally using another Sonoff device as a remote — no internet needed), which means you can control it locally without internet using another Sonoff device.

Ideal for controlling lights, water pumps, fans, or any device you want to switch on/off remotely.

Key Features:

  • Remote Control: Turn devices on or off from your phone, wherever you are.
  • Schedules & Timers: Set devices to turn on/off at specific times automatically.
  • eWeLink-Remote: Control locally without internet using another Sonoff device.
  • Smart Scenes: Create automation rules — e.g., “When I leave home, turn off the lights.”
  • Voice Control: Works with Google Assistant and Alexa.

💡 Pro Tip: This is the best starter device if you’re new to smart home. Use it to make your outdoor or hard-to-reach lights smart — like garden lights, balcony lights, or that one lamp behind the couch nobody wants to get up to turn off.

Basic R4 DIY Smart Switch

The Sonoff Basic R4 is a simple, beginner-friendly smart switch. It connects to your home WiFi, so you can control your lights or other devices straight from your phone, even if you're not at home!

You have two options:

  • Option A:
    • If your AC saves its power state after electricity is restored, you can use a Sonoff Basic Gen5 Matter to control it ON/OFF and set schedules.
    • If your AC does not save its power after electricity is restored, using a Sonoff Smart Plug or Sonoff Basic will not help and you should check the option B.
  • Option B ( If your AC has an infrared remote):
    • You can use the BroadLink RM4 Mini IR to control it on/off and change its temperature and other settings. Check this video to learn how to use the Broadlink to control your AC.
      • Note: The Broadlink does not remember the state of your AC (just like the remote), it just assumes it. So if the AC is off and you turn it on using the Broadlink app, it will turn on, and if it is on and you turn it on as well from the Broadlink app, it will turn off, because the ON/OFF signal is the same IR signal (unless your AC has separate buttons for on and off).
    • Other option compatible with Apple HomeKit

The Sonoff Basic and Sonoff Mini are smart home devices from Sonoff. Both connect via WiFi and can be controlled remotely using the eWeLink app on your phone. However, there are some key differences:

  • The Sonoff Basic is larger in size and can handle various appliances such as heaters and boilers.
  • The Sonoff MiniR4M is smaller and designed for controlling lights and other small appliances only. Its compact size allows it to fit into a single-gang electrical box behind a light switch.
  • Both devices support remote on/off control, scheduling, and are compatible with Matter.
  • Overall, the main difference between the Sonoff Basic Gen5 and Sonoff MiniR4M is their size and design, with the Mini being more compact for smaller installations.

  • The Sonoff Basic Gen5 is a DIY switch, meaning that you will need to use your own wires to link it to input and output.
  • The Sonoff S60 is a smart plug, it does not require any DIY work. You just plug it in your wall outlet.
