Aqara Dual Relay Module T2 – Hidden Zigbee Smart Relay
The Aqara Dual Relay Module T2 is a compact two-channel smart relay for compatible electrical devices.
This dual relay Zigbee module adds intelligent control without replacing existing equipment.
It supports Dry Contact, Wet Contact, and Interlock modes for flexible applications.
The hidden relay connects through a compatible Aqara Zigbee 3.0 hub.
Two-Channel Smart Control
The module provides two relay channels for compatible electrical loads.
Each output can be controlled according to the configured operating mode.
The maximum AC current is 10A combined across both channels.
The rating is not 10A per channel.
Zigbee 3.0 Connectivity
The Aqara Zigbee relay uses Zigbee wireless communication.
A compatible Aqara Zigbee 3.0 hub is required for Aqara Home control.
Users can create supported schedules, scenes, and smart automations.
Dry Contact Mode
Dry Contact Mode enables control of compatible equipment with dry-contact inputs.
It can be useful for certain garage controllers, motors, and control circuits.
Dry Contact wiring must follow the official Aqara diagram.
The Wet Contact jumper must be removed for this mode.
Wet Contact Mode
Wet Contact Mode supports switching compatible electrical loads.
The LIN and LOUT terminals must be bridged using the supplied jumper.
Wiring must follow the official diagram and electrical ratings.
Interlock & Motor Control
The Aqara Dual Relay Module T2 supports Interlock Mode.
This mode is useful for compatible bidirectional motors and shutter systems.
Interlock prevents both direction outputs from operating simultaneously.
It must be enabled and configured correctly before operating motors.
Energy Monitoring
The module supports energy monitoring under its compatible operating conditions.
Readings can support power-related automations in Aqara Home.
Energy monitoring and power automations require AC-powered operation.
These features are not necessarily exposed to third-party ecosystems.
Power Memory
Power Memory allows the relay to manage its state after a power interruption.
Users can configure supported recovery behavior within the Aqara system.
Available settings depend on the device configuration.
Overheat & Overload Protection
The T2 supports protection against overheating and electrical overload.
Customizable power limits are available under supported conditions.
These features do not replace appropriate circuit breakers or electrical safety devices.
Wireless Switch Mode
Wireless Switch Mode can convert a compatible existing wall switch into a scene controller.
Selected wired sensors may also be integrated.
This function requires AC power and Aqara Home.
It is not necessarily available through third-party platforms.
HomeKit & Matter Integration
The relay supports integration with compatible Apple HomeKit smart home configurations.
Matter compatibility is provided through a compatible Aqara hub acting as a Matter bridge.
Google Home and Amazon Alexa integration depends on the hub and platform setup.
The T2 itself is not a Matter over Thread device.
Compact Hidden Installation
The hidden relay module fits compatible wall boxes and electrical enclosures.
It can be installed behind a switch, near a lighting load, or using a DIN rail accessory.
Aqara recommends approximately 60mm of wall-box depth for adequate installation space.
Electrical clearance, heat management, and wiring must be considered.
