Short Description
The Shelly 2PM Gen4 ANZ is a compact, two-channel smart switch with power measurement and cover control. It enables remote control of electric appliances via smartphone, tablet, PC, or home automation systems. The device operates independently on a local Wi-Fi network or through cloud-based home automation services. Compared to its predecessor, it features an upgraded processor and increased memory. It supports Venetian blind control, similar to the Shelly 2PM Gen3.
Remote access, control, and monitoring are possible from anywhere with internet connectivity, provided the device is connected to a Wi-Fi router and the internet.
Designed for retrofitting into standard electrical wall boxes, behind power outlets, light switches, or other space-constrained locations.
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, reliable communication.
This device is Matter-compatible (default device profile: Switch).
