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/.

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.
