Short description

Shelly 1 Gen4 is a small form factor smart switch with potential-free contacts, which allows remote control of electric appliances 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 1 Gen4 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 1 Gen4 has embedded Web Interface, which can be used to monitor and control the device, as well as adjust its settings.

The device has multi-protocol wireless MCU which provides Zigbee and Bluetooth connectivity, ensuring a secure connection.

This device is compatible with Matter.
