# Velux

Control Velux io-homecontrol roof windows from TapHome by wiring its outputs to the KLF 200 interface as dry contacts, one-way, up to 5 devices.

Last updated: 2026-11-06

TapHome controls Velux io-homecontrol roof windows through the Velux KLF 200 interface: you connect TapHome DO outputs to the KLF 200 inputs, and the KLF 200 acts as a bridge to Velux RF control using dry contacts. One KLF 200 interface supports up to 5 Velux devices or 5 groups of devices (up to 200 VELUX products in total), while the KLF 050 controls a single window or blind through a dry contact. Control is one-way only, so TapHome receives no feedback from the windows. Plan the integration early, because wireless Velux units often include their own controllers.

## Overview

Velux offers motorized roof windows that use the io-homecontrol wireless protocol. 

## Integration

### Velux KLF 200 Interface
- Acts as a bridge between Velux RF control and TapHome using dry contacts.
- Connect TapHome DO outputs to the KLF 200 inputs.
- Supports up to 5 Velux devices or 5 groups of devices (up to 200 VELUX products in total).


## Alternative accessories

- **KUX 110**: 24V power/drive unit for operating Velux motors. For integration with TapHome, it must be combined with the KLF 200.
- **KLF 050**: Enables control of a single window or blind using a dry contact.


## Limitations

- No two-way feedback to TapHome (only one-way control).
- Velux wireless units often include their own controllers, which can limit integration if they are not considered during the planning phase.


## Recommendations

- **New builds**: Choose simple wired motors with end stops for direct control from TapHome.
- **Planning phase**: Communicate early with the designer or electrician.
- **Wireless motors**: Use the KLF 200 for integration.

> Advanced control via Home Assistant is possible through the KLF 200 API interface but requires a custom implementation.
