What Is the HomeSYS Z-Wave In-Wall Switch?
The HSYS-Switch-2001 is a single-channel Z-Wave on/off switch that installs inside a compatible electrical wall box. Once installed and paired with a Z-Wave controller, it allows the connected lighting load to be controlled locally, remotely or as part of a smart home automation.
Because it is permanently powered, the switch can also function as a routing node within the Z-Wave mesh. This may help compatible Z-Wave devices communicate more reliably across the home.
Smart lighting does not always require replacing your existing wall switches. The HomeSYS HSYS-Switch-2001 Z-Wave In-Wall Switch is a compact module designed to add smart on/off control behind a compatible wall switch.
Operating on the 921.42 MHz ANZ Z-Wave frequency, it can be controlled through a compatible Z-Wave hub while retaining convenient local control from a connected momentary push-button switch.

- Built-in over-temperature monitoring
- Compact 45.5 × 45 × 20.3mm enclosure
Local and Smart Home Control
The connected load can be switched on or off through a compatible Z-Wave controller. Local control is also available using a connected momentary push-button switch.
The action button on the module can be pressed briefly to switch the connected load on or off. It is also used during Z-Wave inclusion, exclusion and factory-reset procedures.
Compatible Lighting Loads
Before installation, confirm that the connected lighting type and total load remain within the switch's specified limits.
| Lighting Type | Maximum at 220V | Maximum at 110V |
|---|---|---|
| LED lamps with transformers | 200W | 100W |
| LED drivers | 200W | 100W |
| Incandescent and high-voltage halogen lighting | 400W | 200W |
| Low-voltage halogen lighting with electronic transformers | 200W | 100W |
The maximum number of LED lamps may be affected by 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.
Before Installation
Installation must be completed by a licensed electrician. Before selecting this module, confirm the following:
- A neutral conductor is available at the installation point.
- The connected load is compatible and within the stated rating.
- There is sufficient space for the 45.5 × 45 × 20.3mm module.
- A compatible 921.42 MHz ANZ Z-Wave controller is available.
- The 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 Switch to a Z-Wave Network
Once the electrical installation has been safely completed, the switch can be included in a compatible Z-Wave network.
- Follow the instructions supplied with your Z-Wave hub to place it into inclusion or add-device mode.
- Ensure the installed HomeSYS switch is powered.
- Press the action button on the module three times to activate inclusion.
- Wait for the Z-Wave controller to confirm that the device has been added.
The manual also states that the module automatically enters inclusion mode after being powered when it is not already connected to a Z-Wave network. The triple-press method provides a direct way to activate inclusion when required.
How to Remove It from a Z-Wave Network
- Place the primary Z-Wave controller into exclusion or remove-device mode.
- Press the action button on the HomeSYS switch three times.
- Wait for the controller to confirm successful removal.
Removing the device through the controller is the recommended method. Association information is cleared automatically when the switch is excluded from the network.
How to Factory Reset the Switch
Press and hold the action button for more than 10 seconds to restore the switch to its factory-default settings.
Power Recovery Options
The switch supports configurable behaviour after a power interruption. A compatible Z-Wave controller may expose the following options:
- Keep the connected load switched off
- Switch the connected load on
- Restore the load state that was active before the interruption
The factory-default setting restores the load's previous state. Availability and naming of configuration controls may differ between Z-Wave hubs.
Status Reporting and Associations
Association Group 1, known as the Lifeline group, supports up to five nodes. It is used to report important information such as:
- Local factory-reset notifications
- Changes to the connected load's on/off state
- Emergency shutoff notifications caused by over-temperature protection
Basic load-status reporting is enabled by default. Advanced association and configuration options depend on the features exposed by the connected Z-Wave controller.
Temperature Protection
The HSYS-Switch-2001 includes an internal thermistor for temperature monitoring. If an over-temperature condition of approximately 95°C is detected, the switch supports an emergency shutoff status notification through the Z-Wave Lifeline group.
This safety feature does not replace correct installation, suitable ventilation, load selection or compliance with electrical regulations.

Frequently Asked Questions
Does the HomeSYS switch dim lights?
No. The HSYS-Switch-2001 provides on/off control only. A dedicated, compatible dimmer is required for brightness adjustment.
Does it require a Z-Wave hub?
Yes. Smart control and automation require a compatible 921.42 MHz ANZ Z-Wave controller.
Does it require a neutral wire?
Yes. The wiring shown in the product manual includes active and neutral power connections.
Can it be controlled manually?
Yes. The module supports connection to an external 8-230V momentary push-button switch for local operation.
Can it improve Z-Wave coverage?
As a permanently powered routing device, it can help relay compatible Z-Wave communications within the mesh. Actual performance depends on the building layout, controller and surrounding Z-Wave network.
Can I install it myself?
No. This is a mains-powered in-wall device. In Australia and New Zealand, installation must be completed by a licensed electrician.
Final Thoughts
The HomeSYS HSYS-Switch-2001 is a practical option for adding Z-Wave on/off control while retaining a compatible physical wall switch. Its compact enclosure, ANZ Z-Wave frequency, S2 support, OTA capability and configurable power recovery make it suitable for a range of professionally installed smart lighting projects.
Before purchasing, confirm your Z-Wave frequency, available wall-box space, neutral-wire availability and connected load requirements.
