Hub vs Relay Module Specs
Connectivity Protocols
The Aqara M100 Matter and Zigbee Hub offers broader wireless options. It connects via 2.4GHz Wi-Fi 6 and supports Thread and Zigbee 3.0. This allows it to bridge Matter devices and handle local automations with millisecond response times. The Aqara Dual Relay Module T2 relies solely on Zigbee 3.0. It requires a compatible Aqara hub to function. The M100 provides more network flexibility for your home setup, while the T2 is a simpler, protocol-specific endpoint device that needs that central hub connection to operate.
Smart Home Compatibility
Both devices support Matter and Apple HomeKit, but their ecosystems differ. The M100 acts as a Matter bridge, connecting to Amazon Alexa and Home Assistant. It also supports local automation execution for Zigbee and Matter devices. The Dual Relay Module T2 integrates with Alexa, IFTTT, and the Aqara Home app. It requires a Matter-compatible Aqara hub for Matter support. The M100 offers more direct integration with major third-party platforms like Home Assistant, whereas the T2 depends on the hub for broader ecosystem access.
Wiring Requirement
Installation needs vary significantly between these two products. The Aqara Dual Relay Module T2 explicitly requires a neutral line for power. It is designed to be installed behind switches or outlets, or on a DIN rail. The M100 uses a universal USB-A port for power. You can connect it to power banks, wall outlets, PCs, or routers. The M100 offers easier placement options without strict electrical wiring constraints, while the T2 demands specific home electrical infrastructure for proper operation.
Device Capacity
The M100 is designed to manage multiple devices simultaneously. It supports up to 20 Aqara Zigbee devices and 20 Thread devices. It also bridges Aqara Zigbee products to other Matter ecosystems. The Dual Relay Module T2 does not list a device capacity limit because it is an endpoint device, not a hub. It controls two relays. The M100 provides significantly higher capacity for expanding your smart home network, while the T2 is limited to controlling its own connected loads.
Control Features
The Dual Relay Module T2 offers specialized control modes for specific hardware. It supports dry contact mode for boilers or garage doors. It also includes wireless switch mode to convert existing wall switches into scene controllers. It can control tubular motors for roller shades. The M100 focuses on hub functions like local automation and bridging. It does not list direct motor or relay control features. The T2 provides more granular hardware control options for specific appliances, while the M100 focuses on network management.
Physical Dimensions
Size and form factor differ for each product. The M100 measures 4.25 inches in length, 1.18 inches in height, and 0.31 inches in width. It weighs 0.71 ounces. The Dual Relay Module T2 is larger, measuring 1.8 inches in length, 1.89 inches in width, and 0.95 inches in height. The M100 is smaller and lighter, making it easier to hide or place flexibly. The T2 is bulkier, designed for mounting behind switches or on DIN rails. The M100 wins for compactness.
