The Shelly 1PM Gen3 is a small form factor Wi-Fi-operated 16A smart switch with precise power measurement which allows remote control of lights and other electrical appliances (16A AC max/ 10A DC max) 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 1PM 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 some electrical wall boxes, behind power sockets and light switches or other places with limited space - including the Shelly Wall Switch 1. Shelly 1PM Gen3 has an embedded web interface which can be used to monitor and control the device, as well as adjust its settings. Different types of actions, scenarios, and schedules can be set to sync your environment to your daily activities or business needs, via the Shelly smart home ecosystem, including the Shelly Smart Control app - or link it with a popular home automation software such as Home Assistant via a Raspberry Pi!
