The Shelly 2PM Gen3 is a 2-channel WiFi smart relay with power metering and shutter control, a two-in-one device that automates two independent circuits or a roller shutter, awning, or curtain motor. In shutter mode, it offers position control and even louver tilt control for Venetian blinds. Its two independent power meters record real-time consumption for each channel, helping you optimize energy spending. With the new 8 MB Gen3 chip, it is Matter-compatible, integrates with any ecosystem, and executes local automations without relying on the cloud, all in an ultra-compact format that fits behind the switch.
