Short Description
The Shelly 1PM Gen4 ANZ is a compact smart switch with power measurement capabilities, enabling remote control of electric appliances via mobile phone, tablet, PC, or home automation systems. It operates either standalone on a local Wi-Fi network or through cloud-based home automation services.
You can access, control, and monitor the device remotely from anywhere with internet connectivity, provided the device is connected to a Wi-Fi router and the Internet.
It’s designed for retrofitting into standard electrical wall boxes, behind power sockets, light switches, or other confined spaces.
The device includes an embedded web interface for monitoring, control, and configuration. It features a multi-protocol wireless MCU supporting Zigbee and Bluetooth for secure connections. This device is compatible with Matter.
