Short description

Shelly 1L is a small smart switch, which handles the problem of many light switches being difficult to automate, because they can operate without Neutral. Shelly 1L solves this problem, because it only needs the hot line. The device allows remote control of the appliance connected to it through a mobile phone, tablet, PC, or home automation system. It can work standalone in a local Wi-Fi network or it can also be operated through cloud home automation services.

Shelly 1L can be accessed, controlled and monitored remotely from any place where the User has internet connectivity, as long as the device is connected to a Wi-Fi router and the Internet.

It can be retrofitted into standard electrical wall boxes, behind power sockets and light switches or other places with limited space.

Shelly 1L has an embedded Web Interface which can be used to monitor and control the device, as well as adjust its settings.
