Why Shelly 2PM Gen4

The Shelly 2PM Gen4 switches up to 10 A on each channel, and 16 A in total

Two channels

Controls two lights or loads separately from one device, so one module covers two circuits.

Energy metering

Reads the power drawn on the circuit and keeps the energy total, so the app shows what each load uses.

Load rating

Switches loads up to 10 A. The manual lists the limits for lamps, motors and other load types.

Connectivity

Connects over Wi-Fi, Bluetooth and Zigbee. Setup runs from the phone, then the device joins the home network.

Local automation

Up to 20 schedules, scripting, MQTT and webhooks run on the device itself, so routines keep working if the internet drops.

Built-in protection

Overheating protection cuts the output before the device or the load is put at risk.
