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 (mobile phones, tablets
etc.). They can be in the same WiFi network or they can
use remote access (through the Internet - Shelly Cloud).
Shelly® has an integrated web server, through which the
User may adjust, control and monitor the Device. An API
can be provided by the Manufacturer. The User can register and access the Shelly Cloud, using either Android or
iOS mobile applications, or any internet browser and the
web site: https://my.shelly.cloud/.
