Short Description
The Shelly 1 Mini Gen4 is a compact smart switch with potential-free contacts, enabling remote control of electric appliances via smartphone, tablet, PC, or home automation systems. It operates standalone within a local Wi-Fi network or integrates with cloud-based home automation services. As an upgraded version of the Shelly 1 Mini Gen3, it features a more advanced processor and supports Zigbee connectivity.
The device can be remotely accessed, controlled, and monitored from anywhere with internet access, provided it remains connected to a Wi-Fi router. Designed for space-constrained environments, it can be retrofitted into standard electrical wall boxes, behind power sockets, light switches, or other tight spaces.
Built-in web interface allows full monitoring and configuration. The device includes a multi-protocol wireless MCU supporting both Zigbee and Bluetooth for secure, reliable communication. It is also compatible with Matter.
