Short Description
Shelly 1PM Gen3 is a small form factor smart switch with power measurement, 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 be operated through cloud home automation services. The device also features an improved processor and increased memory compared to its predecessor.
Shelly 1PM Gen3 can be accessed, controlled, and monitored remotely from any location with 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, light switches, or other spaces with limited room.
The device includes an embedded Web Interface for monitoring, control, and configuration of settings.
