The Shelly 2PM Gen4 is a compact, dual-channel smart switch designed for next-level home and office automation. With support for WiFi, Zigbee, Bluetooth, and Matter, it offers unmatched flexibility and compatibility across platforms, making it simple to integrate into your preferred smart ecosystem. Its two independent channels can control appliances, lighting circuits, or motorised covers such as blinds, shutters, and curtains — all while delivering real-time power metering for each channel, so you can track energy usage and optimise efficiency.
This device is small enough to retrofit behind existing switches, yet powerful enough to manage bi-directional AC motors with precision. You can control roller shutters, automate curtain schedules, or adjust the tilt of venetian blind slats for the perfect balance of light and privacy. The Shelly 2PM Gen4 also functions as a WiFi and Zigbee range extender and includes a Bluetooth gateway, expanding your network while connecting your devices. Built-in overheating protection, advanced scripting capabilities, and wide protocol support (including Apple HomeKit via Matter) make it a future-proof choice for both residential and commercial automation projects.
