Short description

Shelly1 Mini Gen3 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. The device is an improved version of Shelly Plus 1 Mini with a more advanced processor and increased memory.

Shelly1 Mini Gen3 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.

Shelly1 Mini Gen3 Mini has embedded Web Interface which can be used to monitor and control the device, as well as adjust its settings.
