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 Shelly 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 the Shelly Cloud, using either Android or iOS mobile applications, or any internet browser and the
web site: https://my.shelly.cloud/.
