Shelly Plug S

SHELLY - Shelly Plug S Mini Wi-Fi Smart Plug

La connected socket is one of the basic devices for any beginner in the connected home. It is indeed one of the easiest to install and use. But there is plug connected and plug connected. This can range from the most basic (10A, simple ignition, etc.) to the most complex, like this Shelly Plug S.

sold € 26 excluding promo at Domadoo, this WiFi socket has a lot of advantages like a consumption monitoring, the data extraction, controllable by voice, system of security and it will also delight home automation fans because it is can be controlled locally thanks to its API and can therefore work with boxes like Home Assistant, Jeedom, Eedomus, Domoticz or even Homey ...

Shelly Plug S: A safe Wi-Fi outlet

Unboxing

The Shelly brand specializes in the design and sale of products for home automation and belongs to the Bulgarian Allterco Robotics. Their products have the particularity of being suitable for home automation through their app.

The connected socket Shelly Plug S is delivered in a packaging incorporating the visual code Shelly, namely a small format (cardboard 7,5 x 4,7 x 4,7 cm) in glossy print, white and blue, quite nice. Always the fun word game with MAKE IoT SIMPLE, IoT being the acronym for Internet of Things or Internet es Objets (IoT in French).

There is the visual of the plug but above all the highlighting of its characteristics and specificities: the operation in Wi-Fi, SSL connectivity, cloud service ...

The Shelly Plug S is well inserted in a cardboard wedge (so we have 100% recyclable). It has a design that is both compact and rather well felt. Without being a canon of beauty, its manufacture in double materials (white and transparent plastic) is quite harmonious. Especially since the bright parts will highlight the light indications of the LEDs. The overall quality is very good, solid and there are no problems with the finish.

At the dimension level, this WiFi socket is compact since she measures 7 cm in length and 4,4 cm in diameter for 60 grams. The 7cm includes the 2cm male plugs and when inserted it will pop out of 3,5 to 4 cm approximately.

There is of course a physical button on the underside (or the top depending on your wall sockets) to control it manually, but also to allow its installation.

The big question is always: " but can I use it with my wall sockets and with all my devices? ". The answer is yes, with a few rare exceptions. It's a take of type E / F, therefore the European standard, totally adapted to our electrical devices. It mixes both the female earth plug (socket E) and the type SchuKo because it also has the metal earth tabs on the sides (socket F) which are now standard.

The female part of the plug is type F, that is to say with the tabs on the top and bottom. There is also a " child protection »Which will avoid coming to introduce objects and sticking to it ...

As with all of its products, Allterco Robotics focuses on compliance with European standards in force 2014/53 / CE (making radio equipment available on the market), 2014/35 / CE (relating to the voltage of these products), 2004/108 / CE (CE marking with regard to electromagnetic compatibility (CEM)) and RoHS 2.

Its small size and successful design mean that this socket can be put quite easily, in the smallest space. Only the physical button is quite small and not necessarily very well placed. Let's look at the features. But before that, did you know that we say a socket? Because with this small object, we come to take the current where it is, in the network.

Shelly Plug S: installation and use

The Shelly app

 

Allterco Robotics has developed the Shelly application to drive all of its products and thus provide them with a single ecosystem. As much to tell you right away, it has undeniable advantages, but the installation system is downright lousy. As for the thermometer / hygrometer Shelly H&T, we took a long time to install this product. If that doesn't work right away, take your trouble patiently.

First of all, it is necessary to create an account then create one or more parts. The products installed must be associated with a zone in order to be able to be used. They are stored in a waiting area while waiting. To create these parts, select « Add room » and let yourself be guided. You can come and put the photo you like, name it, ...

During this time, or after, plug in the plug. It will flash blue and red to signify that it is in pairing mode.

There is also different status of the LED:

  • Fast blinking blue : AP mode
  • Slow blinking blue : STA mode (without cloud)
  • Solid blue : connected to the cloud (STA) and running (it is plugged in, the current is flowing)
  • Red Fixed : socket on
  • Fast blinking blue and red : update

If it doesn't blink, press 10 seconds on the physical button and it should.

Once done, in the app, tap « Add device », enter your Wi-Fi settings, then wait. Once the plug is detected, select it and do " add ". You will return to the home screen and you will have to wait for a message to inform you that the product is available for the future and attached to your Wi-Fi network.

But it's not that simple ... Now we have to wait for the headband " Discovered devices »Is displayed ... What may never happen. We made several attempts, used several telephones, without success. Not to mention the times when devices disappear. When it works, you have to select module by clicking on the banner and choose the room where you want to install the socket.

The installation could not be more painful: you have to install the module on your Wi-Fi and then install it in a room. Add to that cloud connections all over the place and an unstable app that loses settings along the way, and you end up with a lousy installation procedure that makes you want to throw it all away! But, once calm has been regained and the mission accomplished, the Shelly Plug S is beautiful and well in place, but above all can be configured as desired!

By selecting the plug, you will be able to access the parameters that will delight more than one:

  • timer : You will come here to determine precise times when to switch the plug on or off (sunrise, after x seconds ...)
  • Weekly schedule : This is a schedule for switching on and off at specific times.
  • Safety : Very interesting parameter. You will be able to define a security which will put the socket on standby if the power exceeds a certain value. It can prevent power surges. It is really very good!
  • Internet Security : you can come and assign a fixed IP to the module, manage the network connection, etc. Very practical for home automation.
  • I / O URL Actions : useful for automations via API's.

Consumption monitoring is really well done. You will have a visual for the day, week, month, year or over a specific period. The histograms are quite readable. By clicking on it, you will have the precise value over the period. In addition, each record (day, week, etc.) gives you the total consumption at the top left of the graphs. This is a very big strong point! A real pleasure !

With Amazon Alexa

Activate the Skill Shelly Cloud with your Shelly credentials and let the app search for compatible equipment. Your device will quickly appear in the app.

 

As with all plugs connected, you can turn it off and on with the virtual button, but also the pilot by voice saying for example " Alexa, switch on socket X " or " Alexa, turn off socket X ". However, no consumption follow-up, neither visually nor orally. Too bad but the functionality is not integrated into the voice assistant.

With Google Assistant

To use it, come and activate the add-on Shelly Smart Home. The device goes back into the app Google Home.

Like with Alexa, you have a virtual button to turn it on and off, but it is of course possible to ask " OK Google, turn on Shelly Plug S ».

Daily, the Shelly Plug S is very stable. It does not disconnect and is very responsive. Mainly by voice. With the Shelly Cloud app, there is a little latency to turn it off (1 to 2 seconds). The big strong point is also the possibility of extracting consumption data from the outlet in spreadsheet form. You will be able to do even more extensive follow-ups! It's the only connected outlet we've tested that allows this (and safety!)! So she is perfect, or almost.

We invite you to get a more precise idea of ​​the H&T via our video (like, subscribe, it's nice):

In conclusion, Shelly hits hard again with this product. The Plug S, connected via Wi-Fi, will give you your power consumption by the hour, the day, the week, the month, the year and at will! She is voice controllable and usable with home automation solutions ! The Shelly application allows a presentation of values ​​in the form of a graph but is always also poor installation level, to put it another way. You also have the ability to extract raw data consumption monitoring, but also to define a maximum power from which it is faulty for protect your devices. Offered at a rate of € 25.99 at Domadoo, the Shelly Plug S will delight beginners and home automation enthusiasts.
Did i choose Alexa or did she choose me? Let's say that as a beta tester, it's a bit of both! And I do not regret having met our favorite assistant nor this adventure undertaken with Alexien Modo. Technophile, self-taught and loving popularization, I try to make our common passion easy to access!
