Wi-Fi controlled smart switch with two channels, 16 A total current (18 A peak)
The Shelly 2PM Gen3 is a smart switch with two-channel control, power measurement, and coverage control. You can remotely control and monitor two different circuits or roller shutters, blinds, and other bidirectional motors. Perfect for retrofitting standard electrical boxes, sockets, and light switches – even in tight spaces.
- Two channels on the same phase
- Power measurement on each channel
- Roller shutter control – Automate and adjust the position of roller shutters, blinds, gates, curtains, awnings, sliding doors, and other bidirectional motors
- Slat angle control – Use the switch for your blinds and control the tilt position (angle) of the slats to adjust how much light enters a room.
- New processor – ESP-Shelly-C38F chip with increased memory capacity of 8 MB
- Improved durability of terminals
- Virtual components
- Wi-Fi repeater & Bluetooth gateway
- Supports scripting, webhooks, MQTT, WebSocket, HTTPS, UDP, TLS, and custom certificates
- No HUB required! Easy control via the Shelly Smart Control App, various home automation protocols, platforms, and voice assistants
- Supports KNXnet / IP communication
