Shelly 1L works with neutral line or without neutral line. Bypass is required for resistive loads below 20W without connected neutral.

Note 3:

Shelly 1L has not dry / voltage-free / pontential-free contacts.

Note 4:

The device only works on 2.4 GHz WiFi b/g/n.

Note 5:

The device does not work only on 5 GHz WiFi ac.

Note 6:

The device supports REST API control and MQTT protocol.

The WiFi Relay Switch Shelly 1L may control 1 electrical circuit up to 4.1A. It is intended to be mounted into a standardin-wall console, behind power sockets and light switches or other places with limited space. Shelly may work as a standalone device or as an accessory to another home automation controller.

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 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 web site: https://my.Shelly.cloud/.
