Aqara Dual Relay Module T2 – Smart Dry-Contact Relay for Garage Doors & Roller Shades (HomeKit & Alexa, Neutral Line & Zigbee Hub Required)

Overview

The Aqara Dual Relay Module T2 is a compact, intelligent relay designed to bring dry-contact control to a variety of everyday devices. Its small footprint makes installation discreet, whether tucked behind a wall switch or mounted near a lighting fixture. With safety features and flexible automation options, it’s built to blend into many smart home setups without crowding your electrical panel.

Broad ecosystem compatibility

Designed for seamless integration, the T2 works with Apple HomeKit, Amazon Alexa, Matter via an Aqara hub, IFTTT, and the Aqara Home app. This wide support helps you connect the T2 to existing routines, scenes, and automation across different ecosystems.

Dry Contact Mode: broad applicability

In dry contact mode, the unit can switch loads without supplying power to the load itself. This makes it suitable for devices such as boilers and garage doors, enabling safer, more flexible automation within your smart home projects.

• Supports both pulse and on-off switching for versatile control
• Ideal for integrating non-powered devices into automations

Flexible control options

Wireless Switch Mode lets you convert an existing wall switch into a scene controller without rewiring. It can also drive tubular motors for roller shades, using basic up/stop/down control (no percentage control).

• Turn a conventional switch into a smart scene controller
• Roller shade control with simple up/stop/down actions

Energy awareness and reliability

Energy monitoring is available in wet contact mode, and Zigbee helps lower idle power compared with Wi-Fi relays. A power-off memory feature retains the last state after power interruptions, adding reliability to automations.

• Energy monitoring option in wet contact mode
• Low idle power with Zigbee and last-state memory after outages

Safety, placement, and installation

Overheat and overload protections are built in, with a customizable power limit to safeguard your home and energy footprint. The T2 can be installed near a light, behind a switch or wall outlet, and includes a DIN rail mount. Dimensions: 1.80 × 1.89 × 0.95 inches.

Real-world use cases

Imagine linking a heating system, door sensor, or lighting scene to a single T2 module. The dry-contact design supports a range of devices, while the compact form keeps installation tidy and unobtrusive.
