At Oz Smart Things, we're proud to offer versatile, innovative solutions that make smart home integration simple and effective. One popular product that’s been getting attention lately is the SR-ZG2835RAC(AU) Oz ZigBee Rotary Smart Dimmer.
A recent customer had a great question about using this dimmer in a two-way lighting circuit — a setup common in many Australian homes. Let’s break it down and answer all your questions.
The Scenario:
-
The customer has a non-smart 2-way lighting circuit.
-
One switch point currently has a rotary dimmer.
-
They’d like both switch points to have rotary dimming control and on/off capability.
Do You Need Two Smart Rotary Dimmers?
Yes — to achieve dimming and switching functionality at both points, you'll need to install two SR-ZG2835RAC(AU) Rotary Smart Dimmers.
Each dimmer can be installed behind a standard wall switch (replacing the existing dumb rotary or toggle switch), allowing you to:
-
Turn the lights on and off from either location.
-
Control dimming through either of the smart rotary dimmers or via your Zigbee-connected app.
This setup allows for full flexibility and a more integrated smart lighting experience.
Does the Dimmer Support Two-Way Switching?
Yes, the SR-ZG2835RAC(AU) supports two-way switching. This means you can control the on/off state of the light from either of the two switch points — just like a traditional two-way setup.
However, it’s important to note:
-
Dimming via the rotary dial only works at the physical switch that has a smart dimmer installed.
-
App-based dimming is available once the device is connected to your Zigbee smart home hub or app (such as Home Assistant, SmartThings, etc.).
-
The other switch point can still turn the light on/off, but won't dim unless it also has a smart rotary dimmer installed.
Wiring Guidance:
This dimmer does support two-way wiring, but it must be done correctly to ensure both safety and functionality.
📌 Refer to the wiring diagram provided with the product or consult a licensed electrician for setup.
Conclusion:
If you're upgrading a 2-way lighting circuit and want full on/off and dimming control at both switch points, we recommend using two SR-ZG2835RAC(AU) ZigBee Rotary Smart Dimmers.
This ensures seamless smart functionality, local rotary dimming, and app control across your setup.
