Description
The Aqara Dual Relay Module T2 is a compact yet powerful smart relay module designed to upgrade conventional electrical devices and systems without requiring a full equipment replacement. Whether you want to automate lighting, roller blinds, garage doors or heating loads, this module works behind the scenes to convert your existing switches or circuits into smart ones. It supports both dry-contact and wet-contact modes, giving you flexibility to integrate resistive loads, motors or legacy control systems. It uses Zigbee 3.0 for reliable, low-power wireless communication and, when paired with a compatible hub, becomes part of major ecosystems such as Apple Home, Google Home and Amazon Alexa. The installation is intentionally flexible: the module can be mounted in standard wall boxes, on a DIN-rail in an electrical cabinet, or tucked behind an existing wall switch. With built-in features such as energy monitoring, power-state memory (to restore the last state after a power failure) and safety protections (over-temperature/over-load), the T2 is designed for both smart-home functionality and robust performance.
