There are more and more Internet of things (IoT) supported nowadays. Yup, check out ITEAD Wi-Fi S20 Smart Socket that I have. It can make your 'dumb' electric appliances to be smart and get connected to the Internet. It comes with EU, US, UK and CN plug standard. Turn on/off any connected device with eWeLink app or by pressing the manual control knob of the WiFi outlet. Or set timers to auto-turn on / off it. Sound great? Let's find out...

Installation is pretty much simple and fast. Basically, you need to create account in eWeLink application. Connect S20 Smart Socket to your wireless router. That's it. No worry, just follow the steps by steps instructions in the app will do.



Software
E-Welink is a free universal smart home remote control software. It can remotely control hardware products of different types and brands including ITEAD. You can download it from Google Play Store and Apple App Store. It supports dozens of smart devices, including smart socket, LED lamp, fan, heater, air purifier, etc.



Performance Result
ITEAD S20 Smart Socket wireless range is excellent. I have no problem to get it connected from the farthest place - kitchen away from the wireless router. Yes, it can be connected on any wall socket in my double storage house. As for usage, it is straight forward. You can turn on / off the connected device manually through eWeLink app. Or set timer that suit your needs. That's it.



By the way, Amazon Alexa is supported as well. Too bad that I don't have Amazon Alexa to test it. So you need to try it yourself in this case. For your information, eWeLink is connected to their cloud server for all the process. If the server cannot be accessed, you still can control S20 Smart Socket but limited to local network only.

Advantages

• Ease your life & save electric bill
  
• Excellent wireless range
  
• Decent build quality

Limitations

• Lot of app permissions needed

What if wifi network's down?
Can it still turn on/off according to timer schedule?

Just like other IoT devices, no Internet == not working.

Sonoff basic still can turn on/off according to timer even when wifi is down.
Which is why I'm curious if it's the same thing with s20

It can still keep to all its schedules even with wifi down

Hai I have a problem with my Sonoff S20,
I test connect to my office Access Point = OK, connect to my house TP-AC1200 = failed

Do I need to set anything special on my house router ? * Note house DHCP enable + firewall disable

Thank you......

I got the same router. No problem connecting the s20 to it
Make sure to connect to the 2.4GHz band

i have this one.really convenience..pair it with two water pump to watering my superhot chilli garden..works perfectly


Attached image(s)

YA at first I accidently connect with 5GHz ... than retry again with 2.4GHz but cannot d

maybe reset the S20 and connect again like brand new

how to reset ? is it because i try ok in office ... change place cannot use ?

Yup you cannot connect it at one location then take it to another. The first time it connects to one wifi id then it looks for that id

I’m sure your office ssid and password is different from your home wifi
Just delete the device from your ewelink app and add it again using your home wifi

Thanks for reply

Already delete the device from list , but at home still cant found, even i try on new phone + new app + new acc + new search still cannot .... bring to office try can detect woh....

headache ...

you need to connect it again at home wifi

from the UI i can see there's not many stuff you can do... right?

With most of the sonoff devices i have i had to use compatibility mode to connect. Try that
