Description
A single-channel Zigbee phase-cut dimmer module designed to retrofit any standard wall switch with intelligent brightness control — no switch replacement required.
Supports trailing and leading edge phase-cut dimming up to 200W for compatible dimmable lighting fixtures and drivers. Installs behind the existing switch in a flush box or on DIN rail. Communicates natively over Zigbee 3.0 with Home Assistant, and integrates with Matter and Apple HomeKit via a compatible hub.

Installation
Requirements
- Existing wall switch in a flush box (≥ 60mm depth recommended)
- Live, Neutral, and Load wires in the flush box
- Zigbee coordinator within range
Turn off the circuit breaker for the affected circuit.
Remove the existing switch plate. The retrofit module sits behind the existing switch — no visible hardware change.
Connect wiring:
- Live → L input
- Neutral → N input
- Load → load output(s)
Fit the module into the flush box. Use DIN rail adapters for panel board installation.
Replace the switch plate.
Restore power. The device will blink — ready to pair.
Pair with your Zigbee coordinator.
Load Limits
- Standard relay: up to 4A direct. For 4–10A, use an external relay/SSR/contactor.
- 40A relay: rated for direct high-current switching. Proper cable sizing and circuit protection mandatory.
- Dimmer modules: resistive and leading-edge dimmable loads only. Not suitable for ceiling fans.
Shutter Module
The shutter module controls motorised curtains, blinds, and shutters:
- M1, M2 → motor up/down terminals
- Configure travel time in your coordinator for accurate position reporting.
