Introduction to Shelly^®

Shelly^® is a family of innovative Devices, which allow remote control of electric appliances through mobile phone, PC or home automation system. Shelly^® uses WiFi to connect to the devices controlling it. They can be in the same WiFi network or they can use remote access (through the Internet). Shelly^® may work standalone, without being managed by a home automation controller, in the local WiFi network, as well as through a cloud service, from everywhere the User has Internet access.

Shelly^® has an integrated web server, through which the User may adjust, control and monitor the Device. Shelly^® has two WiFi modes - access Point (AP) and Client mode (CM). To operate in Client Mode, a WiFi router must be located within the range of the Device. Shelly^® devices can communicate directly with other WiFi devices through HTTP protocol.

An API can be provided by the Manufacturer. Shelly^® devices may be available for monitor and control even if the User is outside the range of the local WiFi network, as long as the WiFi router is connected to the Internet. The cloud function could be used, which is activated through the web server of the Device or through the settings in the Shelly Cloud mobile application.

The User can register and access Shelly Cloud, using either Android or iOS mobile applications, or any internet browser and the web site: https://my.Shelly.cloud/.

Installation Instructions

Danger of electrocution! The mounting/ installation of the Device should be done by a qualified person (electrician).

Danger of electrocution! Do not connect the current transformer clamp to the Line, before wiring it to Shelly EM. Even if only the current transformer is connected, there might be high voltage across its connection cables.

Danger of electrocution. Even when the Device is turned off, it is possible to have voltage across its clamps. Every change in the connection of the clamps has to be done after ensuring all local power is powered off/disconnected.

Do not connect the Device to appliances exceeding the given max load!

Connect the Device only in the way shown in these instructions. Any other method could cause damage and/or injury.

Before beginning the installation please read the accompanying documentation carefully and completely. Failure to follow recommended procedures could lead to malfunction, danger to your life or violation of the law. Allterco Robotics is not responsible for any loss or damage in case of incorrect installation or operation of this Device.

Use the Device only with power grid and appliances which comply with all applicable regulations. short circuit in the power grid or any appliance connected to the Device may damage the Device.

RECOMMENDATION: Тhe Device may be connected to and may control electric circuits and appliances only if they comply with the respective standards and safety norms.

MOBILE APPLICATION FOR MANAGMENT OF SHELLY^®

Shelly Cloud gives you opportunity to control and adjust all Shelly^® Devices from anywhere in the world.

You only need an internet connection and our mobile application, installed on your smartphone or tablet.

To install the application please visit Google Play (Android - fig. 3) or App Store (iOS - fig. 4) and install the Shelly Cloud app.

Registration

The first time you load the Shelly Cloud mobile app, you have to create an account which can manage all your Shelly^® devices.

Forgotten Password

In case you forget or lose your password, just enter the e-mail address you have used in your registration. You will then receive instructions to change your password.

Be careful when you type your e-mail address during the registration, as it will be used in case you forget your password.

After registering, create your first room (or rooms), where you are going to add and use your Shelly devices.

Shelly Cloud gives you opportunity to create scenes for automatic turning on or off of the Devices at predefined hours or based on other parameters like temperature, humidity, light etc. (with available sensor in Shelly Cloud).

Shelly Cloud allows easy control and monitoring using a mobile phone, tablet or PC.

Device Inclusion

To add a new Shelly device, install it to the power grid following the Installation Instructions included with the Device.

Step 1
After the installation of Shelly in the console behind the power socket/light switch and the power is turned on Shelly will create its own WiFi Access Point (AP).

In case the Device has not created its own WiFi network with SSID like shellyem-35FA58 check if you have connected Shelly correctly by the schemes described above. If you do not see an active WiFi network with SSID like shellyem-35FA58, reset the Device. In order to reset the device, you will need physical access to it. On the back of the device, you will see a button. Press and hold it for 10 seconds. Shelly should return to AP Mode. If not, please repeat or contact our customer support at: support@Shelly.cloud

Step 2
Choose "Add Device".

In order to add more Devices later, use the app menu at the top right corner of the main screen and click "Add Device". Type the name (SSID) and password for the WiFi network, to which you want to add the Device.

Step 3
If using iOS: you will see the following screen:

Press the home button of your iPhone/iPad/iPod. Open Settings > WiFi and connect to the WiFi network created by Shelly, e.g. shellysem-35FA58.

If using Android: your phone/tablet will automatically scan and include all new Shelly Devices in the WiFi network that you are connected to.

Upon successful Device Inclusion to the WiFi network you will see the following pop-up:

Step 4
Approximately 30 seconds after discovery of any new Devices on the local WiFi network, а list will be displayed by default in the "Discovered Devices" room.

Step 5
Enter Discovered Devices and choose the Device you want to include in your account.

Step 6
Enter a name for the Device (in the Device Name field). Choose a Room, in which the Device has to be positioned. You can choose an icon or add a picture to make it easier to recognize. Press "Save Device".

Description of Shelly EM values:

1. Power Consumption
   This is the power which is actually consumed or utilized in an AC Circuit is called True power, Active power or Real power. It is measured in kilo watt (kW) or mega Watt (MW). It is the actual outcomes of the electrical system which runs the electric circuits or loads. This is the energy which you are paying. It is shown in blue color in the history graph.
   If you have solar panel and sell energy, you will see this power with "negative" value. It is shown in green color in the history graph.
2. Reactive power:
   This is the power that flows back and forth, it moves in both the direction in the circuit or react upon itself. The Reactive power is measured in Volt-Ampere reactive (VAR), Kilo Volt-Ampere reactive (VAR) or Mega Volt-Ampere reactive (MVAR). You are not being charged for this energy.
3. Power Factor:
   The power factor of an AC electrical circuit is defined as the ratio of the real power absorbed by the load to the apparent power flowing in the circuit, and is a dimensionless number in the closed interval of −1 to 1. A power factor of less than 1 indicates the voltage and current are not in phase, reducing the instantaneous product of the two. In a perfect situation the Power Factor is close to 1.
4. Voltage:
   Voltage, also called electromotive force, is a quantitative expression of the potential difference in charge between two points in an electrical field.
