What Is the HomeSYS Z-Wave In-Wall Dimmer?
The HSYS-Dimmer-2001 is a compact, single-channel in-wall module designed to switch compatible lighting on or off and adjust its brightness. Once installed and paired with a suitable Z-Wave controller, it can be operated remotely or included in scenes, schedules and smart home automations.
As a permanently powered Z-Wave device, the dimmer can also route compatible Z-Wave communications. This may help strengthen the reliability and coverage of the surrounding Z-Wave mesh network.
Smart lighting is about more than switching lights on and off. The HomeSYS HSYS-Dimmer-2001 Z-Wave In-Wall Dimmer adds adjustable brightness control to compatible lighting while allowing you to retain a suitable physical wall switch.
Designed for Australian and New Zealand Z-Wave networks, the dimmer operates on the 921.42 MHz ANZ frequency. It supports remote brightness control, configurable dimming behaviour, Z-Wave automation and local operation using a compatible momentary push-button switch.

Compatible Lighting Loads
The connected lighting must be dimmable and compatible with the selected dimming method. Confirm the lamp or driver's requirements before installation.
| Lighting Type | Maximum Load at 220V |
|---|---|
| Dimmable LED lamps | 200W |
| Dimmable LED drivers | 200W |
| Incandescent and high-voltage halogen lighting | 400W |
| Low-voltage halogen lighting with electronic transformers | 200W |
The maximum number of LED lamps can vary depending on lamp design and power factor. For LED drivers, divide the permitted total wattage by the nameplate power rating of each driver to determine the maximum quantity.
Why Minimum Brightness Matters
Some LED lamps become unstable, flicker or switch off when dimmed below their supported operating level. The HSYS-Dimmer-2001 allows a suitable minimum brightness to be saved.
Once configured, the dimmer will avoid operating below that level, helping improve performance with compatible dimmable lighting.
Setting Minimum Brightness
- Adjust the connected light to the desired brightness.
- Ensure the current level is between 1% and 50%.
- Press and hold the Min.Set button for three seconds.
To clear the saved minimum level, set the brightness to 0% or above 50% and hold the Min.Set button for three seconds.
Setting Startup Brightness
Startup brightness can help compatible LED loads switch on reliably, especially where very low brightness levels may not provide enough power for the lamp or driver to start correctly.
- Set the light to the desired startup level between 1% and 99%.
- Press the Min.Set button twice.
To clear the saved startup level, switch the brightness to 0% and press the Min.Set button twice.
Leading-Edge and Trailing-Edge Dimming
The dimmer supports both leading-edge and trailing-edge operation. The appropriate setting depends on the connected lamp, LED driver or electronic transformer.
- Trailing edge: Configuration value 0 and the factory default
- Leading edge: Configuration value 1
Always check the lighting manufacturer's specifications. Selecting an unsuitable dimming method can result in poor performance, noise or flickering.
Before Installation
Before selecting this dimmer, confirm the following:
- A neutral conductor is available at the installation point.
- The connected lamps or drivers are specifically dimmable.
- The total connected load is within the stated rating.
- The correct leading-edge or trailing-edge method is known.
- There is sufficient space for the 45.5 × 45 × 20.3mm module.
- A compatible 921.42 MHz ANZ Z-Wave controller is available.
- The installation location is indoors and protected from moisture.
The electrical supply must be switched off and secured against being switched back on before installation begins.
How to Add the Dimmer to a Z-Wave Network
Once electrical installation has been safely completed, follow these steps to include the dimmer in a compatible Z-Wave network:
- Follow the hub manufacturer's instructions to place the Z-Wave controller into inclusion or add-device mode.
- Ensure the installed dimmer is powered.
- Press the dimmer's action button three times.
- Wait for the connected light and controller to confirm successful inclusion.
According to the manual, the connected light remains steadily illuminated for approximately three seconds when inclusion is successful.
The dimmer may also automatically enter inclusion mode after being powered when it is not already connected to a Z-Wave network.
How to Remove the Dimmer from a Z-Wave Network
- Place the primary Z-Wave controller into exclusion or remove-device mode.
- Press the dimmer's action button three times.
- Wait for the controller to confirm successful removal.
Removing the device through the controller is the recommended process. Association information is automatically cleared when the dimmer is excluded.
How to Factory Reset the Dimmer
Press and hold the action button for more than 10 seconds to restore the dimmer to its factory-default settings.
Advanced Z-Wave Configuration
A compatible Z-Wave controller may expose the following advanced settings. The names and availability of these controls can differ between platforms.
| Setting | Available Options |
|---|---|
| Power recovery behaviour | Stay off, switch on or restore the previous load state |
| Default fade time | Instant, 1-127 seconds or 1-127 minutes |
| Minimum brightness | Values from 0 to 50 |
| Dimming method | Trailing edge or leading edge |
| Dimming curve | Linear or logarithmic |
| Startup brightness | Values from 0 to 99 |
Power Recovery Behaviour
The dimmer can be configured to behave in one of three ways after a power interruption:
- Keep the connected load switched off
- Switch the connected load on
- Restore the load state that was active before the interruption
The manual lists keeping the load switched off as the factory-default setting.
Status Reporting and Associations
Association Group 1, known as the Lifeline group, supports up to five nodes. It can report:
- Local factory-reset notifications
- Changes to the connected load's state
- Emergency shutoff notifications
Basic load-status reporting is enabled by default. More advanced association controls depend on the connected Z-Wave controller.
Temperature Protection
The dimmer contains an internal thermistor. If its internal temperature rises above approximately 90°C, it supports an emergency shutoff status notification through the Z-Wave Lifeline group.
This safety function does not replace correct installation, suitable load selection, appropriate ventilation or compliance with electrical regulations.
