OXT mini relay module 3-channel ZigBee TUYA — compact 3-circuit wireless relay module

OXT mini relay module 3-channel ZigBee TUYA — compact 3-circuit wireless relay module is a compact in-line relay device designed to add remote control and automation to existing lighting circuits, switches and small appliances. The module supports three independent relay channels and connects to ZigBee 3.0 networks under the TUYA ecosystem, enabling wireless control, timers and scene integration while fitting inside standard junction boxes or enclosures.

Advantages

The module offers three isolated relay outputs for independent control of up to three loads and supports common installation behind wall switches or inside junction boxes thanks to its compact footprint. Compatibility with ZigBee 3.0 and TUYA allows integration into existing smart-home setups and use with TUYA-based mobile applications for scheduling, timers and automation rules. Low-latency ZigBee communication and mesh networking improve responsiveness and range when used with a ZigBee gateway.

Suitable for

• Remote switching of lighting circuits (single- or multi-way setups)
• Controlling small household appliances and resistive loads
• Retrofit smart home installations inside junction boxes
• Expanding ZigBee networks and automations in TUYA ecosystems
• Use cases requiring compact, concealed relay modules

Key specifications

• Input voltage: 90–250 V AC, 50 Hz
• Maximum power per channel: LED loads up to 150 W; resistive loads up to 650 W
• Maximum current: 3 × 3.3 A
• Protocol: ZigBee 3.0 (TUYA compatible)
• Channels: 3 independent relay circuits
• Compact form factor suitable for installation in standard junction boxes

How to use

Install the module in a junction box or behind a wall switch ensuring the unit receives full mains supply as required. Wire the live and neutral input and connect each output relay to the load (lamp, appliance or switch). Pair the module with a ZigBee 3.0 gateway compatible with TUYA following the gateway’s pairing procedure. Once paired, configure channels, timers and automation scenes in the TUYA app or other compatible TUYA-based controller. Ensure power is disconnected during installation and wiring is performed by a qualified electrician where local regulations require.

Usage recommendations

Use a ZigBee 3.0 gateway compatible with the TUYA ecosystem for full functionality. Observe the maximum current and power ratings for each channel and avoid inductive loads that exceed the specified values. Allow devices in the ZigBee mesh to relay signals for extended range and reliability; place the gateway and repeaters to ensure consistent coverage in larger installations.
