Introduction to Shelly®

Shelly® is a family of innovative Devices, which allow remote control of electric appliances through mobile phones, PC or home automation systems. 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 monitoring 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 website: https://my.Shelly.cloud/.

Technical Information

• Control through WiFi from a mobile phone, PC, automation system or any other Device supporting HTTP and/or UDP protocol.
• Microprocessor management.
• Shelly may be controlled by an external button/switch.

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 and the power is turned on, Shelly will create its own WiFi Access Point (AP).
WARNING : In case the Device has not created its own WiFi network with SSID like shellydimmer2-35FA58 check if you have connected Shelly correctly by the wiring schemes. If you do not see an active WiFi network with SSID like shellydimmer2-35FA58, reset the Device. If the device has been powered on, you have to power it off and on again. After turning the power on, you have 60 seconds to  press5 consecutive times either switch connected I1/I2. Or if you have physical access to the device, press and hold the reset button 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. shellydimmer2-35FA58.
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 the discovery of any new Devices оn 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”.
