Shelly 2PM Gen4 Dual Shutter Relay with Power Metering

Shelly 2PM Gen4 is a two-channel smart relay for roller shutters, blinds, curtains, awnings and other bi-directional AC motors. It measures power on each channel and supports position and slat-angle control where the installation and motor allow it. It can also switch two independent circuits when configured for that use. The two outputs share one phase and are rated for 10 A per channel, with 16 A total and 18 A total peak; use the total rating when sizing a shared supply. Supply is 110–240 V AC or 24 V DC, and the compact module fits suitable wall boxes. Wi-Fi 6, Bluetooth 5.0 and Zigbee connectivity are available; Matter is the default profile and Zigbee can be selected during setup. Use schedules, scenes, scripts, MQTT and webhooks for automatic opening, closing and shading routines. Check motor compatibility, interlocking and enclosure space before wiring. Have a qualified electrician install mains-connected equipment.
