Troubleshoot Wi-Fi Connection Issues in a Sonoff Smart Plug

Here are some troubleshooting tips to help you get your Sonoff Smart Plug to connect to Wi-Fi:

Make Sure the Plug is in Pairing Mode

First off, if your Sonoff Smart Plug won’t connect to Wi-Fi, start your troubleshooting by checking that the plug is in pairing mode. When in pairing mode, the indicator light on the plug blinks rapidly.

If the indicator light isn’t blinking rapidly, the plug is not in pairing mode. Unplug it from the power outlet and plug it back in. It should enter pairing mode automatically (indicated by fast blinking light).

If it doesn’t enter pairing mode, reset the plug by long pressing the power button (for about 10 seconds) until the light flashes rapidly.

Now start the setup process to see if it connects to your Wi-Fi network.

Reboot Your Router

If the plug is still not connecting to your home Wi-Fi, the Wi-Fi network might be faulty. You can resolve issues with your Wi-Fi network by rebooting your router.

To reboot your router, unplug it from the power source, then wait for about 30 seconds. Next, plug it back into the power source. This will reboot your router, thus refreshing the connection.

If your Sonoff Smart Plug doesn’t connect after rebooting your router, continue to the next step.

Check Your Wi-Fi Band

Sonoff Smart Plugs only work with the 2.4GHz band. If your router has a dual-band, it might be operating on the 5GHz band—which is not supported by Sonoff Smart Plugs.

Check your Wi-Fi band and ensure it’s broadcasting on the 2.4GHz frequency. You can do this via your router’s admin web page—depending on the brand of your router. If you’re not sure how to do this, refer to your user manual or try googling it.

Move the Plug Closer to Your Router

If the problem persists, another fix to try is moving the plug closer to your router. As you probably know, the plug may receive weak Wi-Fi signals from your router if it’s too far from it.

Bringing the devices closer helps to strengthen your Wi-Fi signals for easy connection.

Use the eWeLink App

If you weren’t using the eWeLink App for the setup, this might be the reason for the connection issue. Sonoff Smart Plugs only works with the eWeLink App.

So, if you’ve been trying to set it up with another app (such as the Smart Life App), switch to the eWeLink App and start the setup process again.

Update the Plug’s Firmware and the App

If your Sonoff Smart Plug firmware version is outdated, it might cause some malfunctions during setup. And this might be the reason the device isn’t connecting to your home Wi-Fi network.

Check your Sonoff Smart Plug’s firmware (via the app) and update it—if they’re new updates.

More so, you may experience some malfunctions if the app is not up-to-date. Check your app store and ensure you’re running the current version of the eWeLink App.

Server Issues: Wait for Some Time

If you’ve tried all the troubleshooting steps above without success, you might just have to wait as it could be a global server issue from the app or Sonoff.

You can try checking some forums like Reddit to see if other users are facing the same issues. If so, it could be a general issue, so wait for the problem to be resolved. Then try to connect your plug to Wi-Fi again.
