Short Description
The Shelly 1 Mini Gen4 is a compact smart switch with potential-free contacts, enabling remote control of electrical appliances via smartphone, tablet, PC, or home automation systems. It operates standalone on a local Wi-Fi network or through cloud-based home automation services. This device is an upgraded version of the Shelly 1 Mini Gen3, featuring a more advanced processor and Zigbee connectivity.
It supports remote access, control, and monitoring from anywhere with internet connectivity, provided the device is connected to a Wi-Fi router. The device can be retrofitted into standard electrical wall boxes, behind power sockets, light switches, or other space-constrained locations.
Key features include:
- Embedded Web Interface for configuration and monitoring
- Multi-protocol wireless MCU with Zigbee and Bluetooth (BLE) support
- Compatibility with Matter
