A set of four Shelly 1PM Gen4 smart switches brings control via Wi‑Fi, Zigbee, Bluetooth, and Matter, accurate real‑time energy consumption monitoring, and a compact form factor for in‑wall boxes. It enables remote control of appliances, creation of automations and scenes without a hub, and broad integration with platforms like Alexa, Google Assistant, Samsung SmartThings, and Home Assistant.
Enjoy full control of your home with Shelly 1PM Gen4. Each module supports switching up to 16 A and precise consumption tracking with history in the app. Thanks to support for Wi‑Fi (802.11 b/g/n), Bluetooth 5.0, Zigbee (802.15.4), and Matter, the devices easily integrate into your existing smart home without a central hub. An integrated temperature sensor protects the installation from overheating.
The modules are ultra‑compact for installation behind switches or sockets and can be managed via the Shelly app, a web interface, or integrations such as MQTT, HTTPS, Webhooks, KNXnet/IP, or ShellyScript. Create schedules (up to 20) and scenes by time, day of week, or weather. The device can also function as a Zigbee and Wi‑Fi repeater for better network coverage.
