In-wall 2-channel relay module Fibaro FGS-224 Z-Wave Plus, 100–240V AC, 50/60Hz, max 9.5A, black

Fibaro Double Smart Module FGS-224 is a Z-Wave Plus EU compatible 2-channel in-wall relay module designed to integrate lighting and other electrical loads into home automation systems. The compact module fits behind switches or inside junction boxes and enables independent control of two circuits via Z-Wave network or direct local switches. It supports secure communication, repeats Z-Wave signals for improved network reliability and meets relevant EU directives.

Advantages

The FGS-224 provides two independent channels in a compact housing, allowing control of two devices or circuits from a single module. It supports resistive and incandescent loads, offers secure Z-Wave communication (S0 and S2 Authenticated) and functions as a signal repeater to extend network range. Installation behind switches or inside device housings is possible thanks to its small dimensions, and it can be controlled both remotely over Z-Wave and locally via connected buttons.

Suitable for

• Integrating two lighting circuits into a Z-Wave based home automation system
• Remote and local switching of electrical devices such as lamps or small appliances compatible with resistive/incandescent loads
• Installation behind wall switches or inside junction boxes where space is limited

How to use

Install the Double Smart Module in a junction box or behind a wall switch following local electrical regulations and ensure power is disconnected before wiring. Connect supply and load wires according to the installation diagram provided by the manufacturer, using recommended wire cross-section (0.2–2.0 mm²) and keeping wire lengths within 3 m where specified. Include the device in a Z-Wave network via your controller to enable remote control and configure channels as needed. The module can also be operated using physical buttons connected to its inputs for local control.

Recommendations

Use the FGS-224 with Z-Wave Plus certified controllers and devices for full compatibility. For reliable operation, observe the specified current limits (6 A per channel, 9.5 A total), avoid inductive loads if not supported, and follow installation instructions and local electrical codes. Place the module where radio range is adequate or rely on mesh repeaters to ensure stable Z-Wave communication.
