Shelly 2PM Gen4 — Dual WiFi+Zigbee Relay with Energy Meter
The Shelly 2PM Gen4 (model S4SW-002P16EU) is the fourth-generation home automation relay with multiprotocol connectivity: WiFi 802.11 b/g/n, Zigbee 3.0, Bluetooth BLE 5.0, and Matter. With two independent channels and integrated energy metering, it allows for controlling and monitoring two separate electrical circuits, including shutter mode for automating blinds, awnings, and gates. Power supply 110–240 V AC, 10 A per channel, 16 A total. Dimensions: 37 × 42 × 16 mm. Weight: 30 g.
Unlike previous models, the Gen4 incorporates Zigbee 3.0, also acting as a Zigbee router in mesh networks and a Bluetooth gateway for Shelly BLU devices. Compatible with Matter over WiFi and Zigbee: it integrates natively with Apple HomeKit, Amazon Alexa, Google Home, Samsung SmartThings, and Home Assistant without the need for an additional hub.
Use cases: residential home automation with shutter control, energy monitoring of appliances, installations without stable WiFi via Zigbee network, and professional automation with mJS scripting and KNXnet/IP protocol. No subscriptions, no mandatory hub, with full local control. Official Shelly distribution. Shipping from Spain.

Especificaciones técnicas
The Shelly 2PM Gen4 is a smart switch designed with a compact form factor, ideal for installation in standard electrical wall boxes, behind outlets, switches, or other confined spaces. This module acts as a smart switch with the added capability of power consumption measurement, allowing you to remotely monitor the usage of connected appliances.
The fourth generation is powered by an improved processor (ESP-Shelly-C68F) and integrates Wi-Fi, Bluetooth, and Zigbee connectivity. In addition to acting as a BLE bridge and Zigbee range extender, this device natively supports the Matter standard (with a default device profile of a switch).
Featured Use Cases
Home Automation
- Independent control of two circuits: Ideal for double wall switches (e.g., living room and hallway lights), allowing separate control and power usage monitoring for each channel.
- Smart control of blinds and awnings: Allows control of motorized blinds or curtains, supporting calibration for precise open/close/stop positioning and slat tilt control for Venetian blinds.
- Appliance monitoring: Measures the power consumption of two appliances independently, with the ability to receive alerts if power thresholds are exceeded.
- Bathroom and kitchen ventilation: Use channel 1 for the bathroom fan with humidity-based automation, and channel 2 for an electric towel warmer.
Commercial and Industrial Applications
- Lighting for zones or offices: Automate lighting in two adjacent rooms and record power consumption separately for energy audits.
- Dual motor control: Allows control and monitoring of two low-load motors (e.g., fans, valves, pumps).
- Digital signage control: Use one channel for store sign lighting and the other for a promotional display or kiosk.
