How many devices are in this pack?

The pack contains two identical Shelly 2PM Gen4 modules in one box, each with 2 channels, for a total of 4 switchable channels with power metering.

Can I use both modules together in one apartment?

Yes. Each module installs in its own back box, in different rooms or circuits, and you then combine them into shared scenes in the Shelly app, Home Assistant, Google Home, Alexa, or via Matter.

Which wireless protocols does the 2PM Gen4 support?

Generation 4 supports Wi-Fi 2.4 GHz (802.11 b/g/n/ax), Bluetooth 5.0, Zigbee 802.15.4, and Matter, unlike earlier generations that had only Wi-Fi and Bluetooth.

What is the maximum load per channel?

Each channel switches up to 10 A, and one module supports a maximum of 16 A total (18 A peak) at 110–240 V AC; switching on 24 V DC is also supported.

Is a neutral wire required for installation?

Yes, the 2PM Gen4 needs a neutral in the back box for power. Before ordering the pack, check that both boxes have a live, a neutral, and room for the 37x42x16 mm module.

Can I control roller shutters or blinds with this relay?

Yes, each module has a dedicated blinds and roller-shutter mode where the two channels drive a curtain motor up/down; the other module can stay on regular light control.

About this product

The Shelly 2PM Gen4 is a two-channel smart relay with per-channel power metering, designed for concealed installation inside a wall box. This pack gives you two identical modules in one box — a convenient way to equip two independent circuits, two rooms, or an entire project at once at a lower per-unit cost.<br><br>Each module controls two loads of up to 10 A per channel (16 A total) at 110–240 V~, and also works on 24 V DC. The built-in meter shows voltage, current, and consumption in real time, helping you keep energy costs under control. A roller-shutter and blinds mode lets both outputs drive a curtain motor.<br><br>Gen4 means four protocols in one: Wi-Fi 2.4 GHz, Bluetooth 5.0, Zigbee, and Matter. The module integrates with Home Assistant, Google Home, Amazon Alexa, Samsung SmartThings, and Matter ecosystems, and supports local scenes, schedules, webhooks, and scripting. Overheating, overvoltage, overcurrent, and overpower protection improve the safety of the installation in Moldovan conditions.

Smart scenarios

Three typical automations we set up after the install.

01Morning: warm light + blinds up + climate at 22 °C
02Leaving: lights off, arm sensors, close the gas
03Evening: warm ambient + cinema scene

Where it works

Use cases

In a Chisinau flat, both 2PM Gen4 units sit behind switches in two rooms, joined into one smart-home scene.

One module in the living room, one in the kitchen control lighting with consumption metering.

In roller-shutter mode both channels of one module raise and lower the shade, while the second module controls the lights.

One module in blinds mode drives the curtain motor, the other handles lighting.

An installer equips a turnkey site with a pair of modules and sets up overpower alerts.

Per-channel metering shows the water-heater and underfloor-heating consumption.
