The Oz Matter Light Switch supports multiple methods of 2-way and multi-way switching, giving you flexibility whether you’re working on a new build, a renovation, or a smart home retrofit.
Using the features outlined in the official manual, there are four supported ways to achieve 2-way switching, ranging from traditional hard-wired methods to modern app-based control.

Option 1: Multi-Control Association (App-Based 2-Way Switching – Recommended)
This is the cleanest and most modern way to achieve 2-way switching with the Oz Matter Light Switch.
Using the Multi-Control Association feature in the Tuya / Smart Life app, you can link a channel on one Oz Matter Light Switch directly to a channel on another switch — without creating multiple scenes.
How it works
- Add both Oz Matter Light Switches to the Tuya / Smart Life app
- Go to:
Profile → Multi-Control Association - Select a channel on one switch and associate it with a channel on the other switch
Once linked, pressing either switch will control the same light.
Benefits
- ✅ No additional wiring required
- ✅ Faster and more reliable than scene-based control
- ✅ Cleaner setup for renovations and retrofits
- ✅ No reliance on multiple automation rules
This method is strongly recommended for most smart home installations.

Option 2: Using the 2-Way Terminal on the Oz Matter Light Switch (DIP Switch Method)
The Oz Matter Light Switch includes a dedicated 2-way control terminal on the back of the switch, allowing traditional wired 2-way switching.
This method links one channel per switch using physical wiring and is enabled using the DIP switches located on the rear of the switch.
How it works
- A control wire is run between the switches using the 2-way terminals
- The relevant DIP switch is turned ON to enable 2-way mode
- Power must be OFF when adjusting DIP switches
Important installation notes
- Only one channel per switch can be used for this method
- All switches must be on the same electrical phase
- Maximum combined length of control and active wiring: 50 metres
- DIP switch changes will not activate if power is on
When to use this option
- New builds
- Electrician-preferred traditional wiring
- Situations where app control is not desired
Option 3: Multiple Switches Wired Together (Control Wire Looping)
This option uses multiple Oz Matter Light Switches wired together via their control terminals to create 2-way, 3-way, or up to 4-way switching.
How it works
- Control wires from each switch are connected together
- DIP switches are enabled to allow multi-way operation
- All switches act as shared control points for the same load
Key considerations
- Best suited to new builds or full rewires
- Requires careful cable management
- Control cables and load cables must not be bundled together
- Must comply with the same phase and distance limits
This is a robust but wiring-intensive approach.
Option 4: Scene-Based 2-Way Switching (Automation Method)
This method uses automations (scenes) in the Tuya / Smart Life app rather than wiring or direct association.
Example setup
- Scene 1: When Oz Matter Light Switch A turns ON, Switch B turns ON
- Scene 2: When Switch A turns OFF, Switch B turns OFF
Pros
- No wiring changes required
- Works across different device types
- Can include time-based or conditional logic
Cons
- Requires multiple scenes to fully replicate 2-way behaviour
- Slight delay compared to association or wired methods
- More complex to maintain long-term
This method is best used when mixing devices or when other options are not possible.
Which 2-Way Switching Method Is Best?
| Method | Best Use Case | Wiring Required | App Required |
|---|---|---|---|
| Multi-Control Association | Retrofits & smart homes | ❌ No | ✅ Yes |
| 2-Way Terminal + DIP Switch | Traditional installs | ✅ Yes | ❌ No |
| Control Wire Looping | New builds | ✅ Yes | ❌ No |
| Scene Automation | Mixed devices | ❌ No | ✅ Yes |
Final Recommendation
For most customers and installers, Multi-Control Association with the Oz Matter Light Switch provides the best balance of reliability, simplicity, and future-proofing.
Electricians working on new builds may prefer hard-wired 2-way switching, while scene-based control remains a flexible fallback for complex setups.
