Sonoff S20, the Itead plug


Today we are going to discover the smart health connected socket of Itead, the Sonoff S20. Like any good self-respecting health home automation fan, I too fell for a smart health connected socket.

What can it be good for you say? Well, there are many applications. This makes it possible to transform a simple electrical device (on / off) into a domotized device.

This ranges from TV to desk lamps to the coffee maker. Imagine your coffee maker firing on its own in the morning to prepare your coffee before you get out of bed.

Personally I use it to control an electric heater and my network installation in the attic.

Sonoff S20, bring health home automation to your electrical equipment

You know, I’m a big fan of the products Itead and the Sonoff S20 is no exception to the rule. The Sonoff S20 like many other modules is built around a Wi-Fi module ESP8266. The ability to connect to your Wi-Fi installation is to be controlled via your smartphone.

The plastic is solid and the electrical contact very firm. Note that for the female side mass, it is provided with two tabs, one at the top and one at the bottom of the socket. It is therefore necessary to verify that the socket on the equipment has this characteristic.

Characteristic side what we must remember is that it has a total capacity of 2200 W, that it is CE / RoHS / FCC certified and that its dimensions are 130 * 80 * 78 (mm).

It takes the general shape of a large block taken with a button on its front. This button allows us to manually activate the switch without necessarily going through the smartphone. It is optional but still very practical. To this is added a blue light indicator around the button to indicate whether the socket is activated or not.

Sonoff S20, still as easy to use

It’s very easy to use, just insert the Sonoff S20 between the wall outlet and its electrical equipment. Now let’s go to pairing with the smartphone.

To do this, start by pressing and holding the button, a blue light will flash. Then start the association with the eWeLink application.

We can now take advantage of several interesting features such as remote control, programmable timer and countdown. Small bonus, the Sonoff S20 is compatible with Google health home and Alexa voice assistants but also with the IFTT service.


With its mini price around 11 € and its ease of use, it would be a shame to deprive yourself of it. I have been using it for several months and I am still satisfied with it.

For the most DIYers among you, we will see together in a future article how to associate the Sonoff S20 at our Jeedom health home automation box.

Until the next article, don’t hesitate to read my previous articles on Sonoff products, see you soon.
