Light switch Homematic IP HmIP-FCI6, white, button control, battery (AAA), IP20, 48.5×15×53 mm

Homematic IP HmIP-FCI6 is a compact, battery-powered contact interface in white designed to integrate existing switches and pushbuttons into a Homematic IP smart-home system. With dimensions of 48.5 × 15 × 53 mm and an IP20 rating, this device is intended for indoor flush-mounted installation behind standard switch inserts. It operates from a single AAA (1.5 V) battery and is supplied as one unit. The HmIP-FCI6 enables integration of up to six switches or pushbuttons so that familiar control elements can trigger lighting circuits, scenes or other smart-home functions without changing the visible switch design.

Advantages

The HmIP-FCI6 contact interface offers invisible installation behind existing switch inserts and preserves the original appearance of switches and pushbuttons while making them smart. Its flat form factor allows mounting in standard flush-mounted boxes, and compatibility with Homematic IP systems means seamless integration with other components for centralized control. Battery operation removes the need for a power supply connection at the switch location, enabling retrofit installation in buildings where running additional wiring would be difficult.

Suitable for

• Retrofitting conventional wall switches and pushbuttons to Homematic IP without changing switch covers
• Making up to six separate switch contacts smart from a single device
• Indoor installations where a flush-mounted, discreet interface is required
• Locations without convenient mains wiring at the switch position (battery operation)

How to use

Install the HmIP-FCI6 directly behind the existing switch insert in a standard flush-mounted box so that the device remains hidden from view. Connect the switch or pushbutton contacts to the appropriate terminals of the contact interface according to the installation instructions. Insert a single AAA (1.5 V) battery to power the unit. After physical installation, add the device to the Homematic IP system using the app or central control unit and assign the switch contacts to the desired lighting circuits, scenes or other functions. Test each contact to confirm correct operation and response in the system.

Recommendations

Install and wire the contact interface only in compliance with local electrical regulations and with the power supply to the associated circuits switched off. Replace the battery regularly or when the Homematic IP system indicates low battery to ensure reliable operation. Use the device indoors only in dry environments, and avoid locations exposed to moisture or dust beyond an IP20 rating. For installation behind specialty or non-standard switch frames, verify available flush-box depth to ensure the flat housing fits without obstructing the switch mechanism.
