Aqara T2 Smart Double Relay Module

Compact at 45.5 × 48 × 24 mm and weighing only 60 grams, it can be installed behind an existing switch, in a flush-mounted box, in a light fixture, or on a DIN rail thanks to the included accessory. Its dual connectivity in dry contact and wet contact mode allows it to control boilers, garage doors, and rolling gates, as well as conventional lighting circuits: this is the central versatility of the Aqara T2 intelligent dual relay module. An Aqara Zigbee 3.0 hub is required, excluding the Camera Hub G2H.

Dry Contact, Wet Contact, Interlock, and Power-Off Memory

In dry contact mode, the T2 relay sends a pulse or on-off signal to operate tubular motors, gate openers, or motorized valves. In wet contact mode, it directly controls lighting circuits up to 2500W for incandescent or 250W for LED and fluorescent, without replacing the existing installation. Disconnecting a single red connecting wire switches the T2 relay from wet to dry mode. The power-off memory retains the last state after a power outage, ensuring the continuity of automations when power is restored.

Electrical Protection, Energy Monitoring, and Aqara T2 Smart Dual Relay Module as Wireless Switch

Overheating protection, overload, and a customizable power limit automatically cut off the circuit if safety thresholds are exceeded, protecting the installation and connected equipment. Energy monitoring is available in wet contact mode to track the consumption of controlled circuits from the Aqara Home app. By activating wireless switch mode, an existing wall switch transforms into a scene trigger without wiring modifications, allowing, for example, a wired security system to be armed from a physical button: this is one of the most practical applications of the Aqara T2 smart dual relay module.

Matter, HomeKit, and Extended Compatibility

Thanks to the Zigbee 3.0 protocol, the Aqara T2 module benefits from fast local communication and low energy consumption. It can be integrated into Home Assistant via Zigbee2MQTT or ZHA for advanced local control and custom automations. Paired with a Matter-compatible Aqara hub, such as the Hub M3, the module can be exposed to Apple Home, Google Home, Amazon Alexa, and SmartThings, allowing easy integration of lighting, gates, garage doors, or heating systems into a unified smart home ecosystem.

FAQ

Is a neutral wire mandatory to install the T2?

Yes, the T2 dual relay module requires a neutral wire to function. Check for the presence of a neutral in your installation box before purchase.

Can the T2 be used to control a garage door?

Yes, in dry contact mode with a pulse signal, the T2 is compatible with the vast majority of gate openers and garage doors. Ensure that there is no risk of a person being trapped during remote activation.

Does energy monitoring work in dry contact mode?

No, energy consumption monitoring is only available in wet contact mode. In dry contact mode, the T2 does not measure power on connected equipment.

Is the Aqara T2 module compatible with Home Assistant?

Yes. When paired with a compatible Zigbee integration (ZHA, Zigbee2MQTT) or a Matter-compatible Aqara hub, the Aqara T2 module can be used in Home Assistant to control lights, garage doors, boilers, or other connected equipment.
