Remotely control and monitor two different electrical circuits, or roller shutters, blinds, and other bi-directional motors from anywhere, including power monitoring.
- 2 channels on the same phase
- Power metering on each channel
- Cover (roller) control – Automate and adjust the position of roller shutters, blinds, curtains, awnings, bi-directional AC motors.
- Slats angle control – use with your venetian blinds and control the tilt position (angle) of slats to adjust the amount of light in a room.
- New processor – ESP-Shelly-C38F chip with an increased memory of 8 MB
- Improved durability of terminals
- Virtual components
- Wi-Fi range extender & Bluetooth gateway
- Supports scripting, webhooks, MQTT, WebSocket, HTTPS, UDP, TLS and custom certificates
- No HUB required! Easy control through Shelly Smart Control app, various home automation protocols, platforms, as well as voice assistants.
