Aqara Dual Relay Module T2

Live smart without replacing your original equipment

The Aqara Dual Relay Module T2 is a device that employs Zigbee technology to regulate power, controlling the on and off functions. It is capable of managing a range of devices including motors, garage doors, lights, switches, and sockets in two modes: dry contact and wet contact. This module can elevate the intelligence and potential of traditional equipment. Linked to the Apple Home platform, the device can be seamlessly operated via the Apple Home app. Additionally, it is broadly compatible with various third-party platforms. With the aid of a hub, features such as app-based remote control, timing control, and power statistics can be implemented.

Aqara Dual Relay Module T2 Features:

  • Versatile Solution for Home:The T2 is versatile and can be used in various ways. It can be installed in ceiling lights for smart control or in regular wall switches and sockets for remote access. Additionally, it’s suitable for automating coffee machines, air fresheners, electric heaters, roller blinds, and garage roller doors in homes.
  • Apple Home and Matter over Bridge Support*: The T2 is compatible with Apple Home, Matter, Google Home, and Amazon Alexa. It transforms traditional devices into smart ones and seamlessly integrates with multiple third-party systems. This facilitates automated setup and linkage with other compatible products, offering a versatile and user-friendly experience.
  • Interlock and Motor Control: Users can connect the Dual Relay Module T2 to bidirectional motors with ease and safety. Now, the T2 can be used to control tubular motors, as a roller shade switch, and even as the core of the system.
  • Energy Monitoring and Power Memory: The Dual Relay Module T2 includes a power on/off state memory function, remembering the last state after power failure. Additionally, it offers power metering and statistics features.
  • Enhanced Safety and Security: Safety is paramount when dealing with DIY electrical equipment. We prioritize user safety, considering the complexities of installation and use. We allow adjustment of max and min voltage, current, and power values. In cases of abnormal waking states, the power supply is automatically turned off to ensure safety.**
  • Wireless Switch Mode: The convert to wireless switch mode is also supported. Thanks to this feature, the existing wall switch will be able to be converted into a scene controller: arm or disarm the security system, control the curtains or lights just using your old wired switch.***
  • Easy to Use and Installation: The relay’s DIN rail-mounted design makes it easy to stick it in electrical cabinets and other tight spots. Its compact size makes it even more suitable for other wall boxes, including the 86 mm and US-standard ones.****

*Apple Home, Google, Alexa, and Matter are neither natively supported, they are supported over Zigbee bridge.
**The installation of T2 is intended for users who are familiar with electrical installation. We always advise you to contact a professional electrician and only use these instructions as a reference.
***Please note: the sensor or a switch connected to S1/S2/COM contacts should support the voltage that is supplied to the Relay.
****Please note: the T2 supports the maximum current of 10A. And a wall box with a depth of about 60 mm is recommended. In case the existing wall box is not deep enough, you can try to use a Wireless Remote Switch H1 or a surface-mounted or ultra-thin wall switch to control the Relay.

^Professional installation recommended.

Frequently Asked Questions


What is the difference between a dual relay module T2 and a wall switch?

  1. Wall switches can be directly controlled locally, while the dual-control module T2 needs to be connected to the existing traditional switch to achieve local control;
  2. The dual-control module T2 needs to be connected to the neutral and live wires. The wall switch has both neutral and live wire switches and single live wire switches;
  3. The installation position of the dual-control module T2 is more flexible, it can be placed in the junction box, on the ceiling, and in the electrical box at the same time.


What's the difference between a dual relay module T2 and a wireless switch?


The dual relay module T2 is connected to a wire and the most critical role is to be able to remotely and intelligently control the power supply and disconnection of the connected circuit, allowing ordinary electric lights to be transformed into smart lights;

The wireless switch is a controller that can control devices such as the dual relay module T2 by setting it up via the APP, but it cannot directly control the electric light.


What is the difference between a dual relay module T2 and a 2-way control module?


The dual relay module T2 retains the functionality of the previous generation of dual relay module T2s with the addition of a dry node function, which allows for the adaptation of more devices, while optimising the size of the product, which is smaller than the previous generation; an additional Ding rail assembly has been added to allow the product to be placed inside the electrical box.


How to install the dual relay module T2?


Please strictly follow the wiring instructions in the product manual, and it is recommended that it be operated by professional electricians.

  1. If you want to achieve both wireless control and local control. Please follow the wiring diagram to connect a conventional switch. The dual relay module T2 can be placed in the junction box.
  2. If only wireless control is required, please follow the wiring diagram. The 2-way control module T2 can be placed in the ceiling etc.


What are the wiring holes in Dual control module T2 used for?


Dual circuit control module T2 has a total of 9 wiring holes, of which hole N is connected to the zero wire and hole L to the firewire.

  1. If using the wet node mode, the LIN and LOUT holes must be shorted with the supplied red jumper (connect the two holes with wires), the L1 and L2 holes are connected to the luminaire load wires and the S1, S2 and COM holes are connected to the conventional switch.
  2. If using the dry node mode, the LIN and LOUT holes must not be shorted (no wire to connect the two holes), the L1 and L2 holes are connected to the load line of the controlled equipment, the LOUT hole is connected to the common line of the controlled equipment, and the S1, S2 and COM holes are connected to the traditional switch. Please see the product manual for detailed wiring instructions.


How to identify the fire and load wires?


The firewire is generally red, the zero wire is generally black or blue and the luminaire load wire is generally green or yellow. It is recommended to be tested by a professional electrician using professional tools such as an electric pen before installation.


Will the wrong wiring holes short circuit?


If the zero and fire wires are reversed, it can be used normally, but after the equipment is switched off, the firewire on the luminaire holder is not disconnected and there is a risk of electric shock; if the luminaire load wire is mistakenly connected to the L or N hole, it will not be short-circuited, but the equipment will not respond, restore the correct connection and you can use it; please wire the product according to the wiring diagram in the product manual to ensure that the product can be used normally.


What is the maximum communication distance between the Dual Control Module T2 and the gateway?


The communication distance between the dual relay module T2 and the gateway can reach 7-10 meters when separated by a wall; in the case of more walls, it is recommended to connect as close as possible.


How much power do I need for the T2 to work properly?


The dual relay module T2 has no minimum load requirement as it is connected to the zero and fire wires, but requires a maximum load of no more than 2500 W for the total number of circuits.


Does the Dual Control Module T2 support the dual control function?


By using the dual relay module T2 with the wireless switch, the dual control function can be achieved very easily. The wireless switch can be placed in most locations in the home at will and linked to control the dual relay module T2.
