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  TTP 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 website: https://my.Shelly.cloud/.

Installation Instructions

CAUTION! Danger of electrocution. The mounting/ installation of the Device should be done by a qualified person  (electrician).

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 following the installation instructions 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 AP WiFi network with an SSID like shelly- 1 pm-35FA58, please check if the Device is connected accordingly to the  Installation Instructions. If you still do not see an active WiFi network with SSID like shelly1pm-35FA58, or you want to add the Device to another Wi-Fi network, reset the Device. If the device has been powered on, you have to restart by powering it off and on again. After turning the power on, you have one minute to press 5  consecutive times the button/switch connected SW. You have to hear the  Relay trigger itself. After the trigger sound, Shelly should return to  AP Mode. If not, please repeat or contact our  customer support at: support@Shelly.cloud
