Shelly Dimmer 2 Smart WiFi Switch Manual

Smart WiFi Dimmer Switch USER GUIDE

The Shelly® smart WiFi dimmer by Allterco Robotics is intended to be installed directly to your lights in order to control and dim the light. It is intended to be mounted into a standard in-wall console, behind the light switches or other places with limited space. Shelly may work as a standalone device or as an accessory to a home automation controller.
SHELLY DIMMER CANNOT BE CONNECTED AND OPERATE A FAN. DOING SO MAY CAUSE DAMAGE TO THE UNIT OR FAN, INCLUDING CAUSING A FIRE!!!
LEGEND:
SW1 – Switch input 1 for on/off/dimming

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/.

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:
Step 2
Choose “Add Device”.
