Zigbee Relay Switches: Smart, Wireless Control for Energy & HVAC Systems

Zigbee relay switches are the intelligent, wireless building blocks behind modern energy management, HVAC automation, and smart lighting systems. Unlike traditional switches, these devices enable remote control, scheduling, and integration into broader IoT ecosystems—all without the need for rewiring or complex infrastructure. As a leading IoT device manufacturer and ODM provider, OWON designs and produces a full range of Zigbee relay switches that are deployed worldwide in residential, commercial, and industrial applications.

Our products include in-wall switches, DIN rail relays, smart plugs, and modular relay boards—all compatible with Zigbee 3.0 for seamless integration into existing smart home or building management systems. Whether you’re automating lighting, controlling HVAC equipment, monitoring energy usage, or building a custom smart solution, OWON’s Zigbee relays offer reliability, flexibility, and local API access for full system control.


What Is a Zigbee Relay Switch?

A Zigbee relay switch is a wireless device that uses the Zigbee communication protocol to receive control signals and physically open or close an electrical circuit. It acts as a remotely operated “switch” for lights, motors, HVAC units, pumps, and other electrical loads. Unlike standard smart switches, a relay can handle higher currents and is often used in energy management, industrial control, and HVAC automation.

At OWON, we manufacture Zigbee relay switches in various form factors:

  • Wall-mounted switches (e.g., SLC 601, SLC 611) for lighting and appliance control
  • DIN rail relays (e.g., CB 432, LC 421) for electrical panel integration
  • Smart plugs & sockets (e.g., WSP 403–407 series) for plug-and-play control
  • Modular relay boards for OEM integration into custom equipment

All devices support Zigbee 3.0 and can be paired with Zigbee gateways such as our SED-X5 or SED-K3 for local or cloud-based management.


How Does a Zigbee Switch Work?

Zigbee switches operate within a mesh network—each device can communicate with others, extending range and reliability. Here’s how they function in practice:

  1. Signal Reception: The switch receives a wireless command from a Zigbee gateway, smartphone app, sensor, or another Zigbee device.
  2. Circuit Control: An internal relay physically opens or closes the connected electrical circuit.
  3. Status Feedback: The switch reports its state (ON/OFF, load current, power consumption) back to the controller.
  4. Local Automation: Devices can be programmed to react to triggers (e.g., motion, temperature, time) without cloud dependency.

OWON switches also include energy monitoring capabilities (as seen in models like SES 441 and CB 432DP), providing real-time data on voltage, current, power, and energy usage—essential for energy management systems.


Zigbee Relay Switch with Battery & No-Neutral Options

Not all wiring scenarios are the same. That’s why OWON offers specialized versions:

  • Battery-powered Zigbee relays: Ideal for retrofit projects where wiring access is limited. Devices like our PIR 313 multi-sensor can trigger relay actions based on motion or environmental changes.
  • No-neutral wire relays: Designed for older electrical installations without a neutral wire. Our SLC 631 and SLC 641 smart switches operate reliably in two-wire setups, making them perfect for European and North American retrofit applications.

These options ensure compatibility with almost any building infrastructure, reducing installation time and cost.

Zigbee Relay Switch Modules for OEM & System Integration

For equipment manufacturers and system integrators, OWON provides Zigbee relay switch modules that can be embedded into third-party products:

  • PCB relay modules with Zigbee communication
  • Custom firmware development to match your protocol
  • API access (MQTT, HTTP, Modbus) for seamless integration into existing platforms

These modules enable traditional equipment—such as solar inverters, HVAC units, or industrial controllers—to become IoT-ready without full redesign.


Why Use a Relay Instead of a Standard Switch?

Relays offer several advantages in smart systems:

Aspect Standard Switch Zigbee Relay Switch
Load Capacity Limited to lighting loads Handles motors, pumps, HVAC (up to 63A)
Integration Standalone operation Part of a mesh network, enables automation
Energy Monitoring Rarely available Built-in metering (e.g., CB 432DP, SES 441)
Control Flexibility Manual only Remote, scheduled, sensor-triggered, voice-controlled
Installation Requires neutral wire in many cases No-neutral options available

In applications like HVAC control, energy management, and lighting automation, relays provide the robustness and intelligence needed for professional-grade systems.


Real-World Applications & Solutions

OWON’s Zigbee relay switches are deployed in:

  • Hotel Room Management: Control lighting, curtains, HVAC, and sockets via a single gateway (SED-X5).
  • Residential Heating Systems: Automate boilers, heat pumps, and radiators with TRV 527 and PCT 512 thermostats.
  • Energy Monitoring Systems: Use clamp meters (PC 321) and DIN rail relays (CB 432) to track and control circuit-level consumption.
  • Smart Offices & Retail Spaces: Combine motion sensors (PIR 313) with relays for occupancy-based lighting and HVAC control.

Each solution is backed by OWON’s device-level APIs and gateway software, enabling full local or cloud integration.


FAQ: Zigbee Relay Switches

Q: Do Zigbee relays work without the internet?
A: Yes. OWON’s Zigbee devices operate in a local mesh network. Control and automation can run via a local gateway without cloud access.

Q: Can I integrate OWON relays with third-party systems?
A: Absolutely. We provide MQTT, HTTP, and Modbus APIs for gateway- and device-level integration.

Q: What is the maximum load for your relays?
A: Our DIN rail relays support up to 63A (CB 432), while wall switches typically handle 10A–20A loads.

Q: Do you offer custom relay modules for OEM projects?
A: Yes. OWON specializes in ODM services—we can customize hardware, firmware, and communication protocols to match your requirements.

Q: How do I power a Zigbee switch in a no-neutral setup?
A: Our no-neutral switches use trickle current through the load to power the Zigbee radio, ensuring reliable operation without a neutral wire.
