It switches 2500 W resistive and 10 A per channel, adds interlock mode for shades and gates, and guards against overvoltage, overcurrent and overpower, none of which the Shelly 1 Mini Gen4 documents. The Shelly 1 Mini Gen4 answers with size and reach: a 29 x 34 x 16 mm body, Wi-Fi and Bluetooth on board, native Matter, a longer warranty and direct support from Alexa, Google Home, Apple Home and SmartThings without a hub brand in between. Both need a neutral wire and both offer dry and wet contact modes. Choose the Aqara Dual Relay Module T2 if you already run an Aqara hub and need two channels, and the Shelly 1 Mini Gen4 for a crowded box with one light or one gate opener.

What the differences mean

Channels and load per channel

The Aqara Dual Relay Module T2 has two channels, each rated for 2500 W resistive and 10 A, so one module can drive a fan and its light or two separate circuits. The Shelly 1 Mini Gen4 has one channel at 2000 W and 8 A, so a second circuit means a second module.

Protections and monitoring

The Aqara Dual Relay Module T2 documents overheating, overvoltage, overcurrent and overpower protection and reports energy use. The Shelly 1 Mini Gen4 lists overheating protection only and has no energy monitoring, which matters if you want to see what a heater or pump draws.

Size

The Shelly 1 Mini Gen4 measures 29 x 34 x 16 mm against 45.5 x 48 x 24 mm for the Aqara Dual Relay Module T2. In a shallow or crowded switch box that gap decides whether the relay fits at all.

How it reaches your home

The Shelly 1 Mini Gen4 joins 2.4 GHz Wi-Fi and Bluetooth directly and lists Matter as supported, so it works without a bridge. The Aqara Dual Relay Module T2 is Zigbee only and needs an Aqara hub for Alexa, Google Home, Apple Home and Matter, though it also works with Home Assistant and SmartThings.

Warranty

The Shelly 1 Mini Gen4 is covered for 3 years and the Aqara Dual Relay Module T2 for 1 year, a real gap for a part that sits behind a wall.

What owners say

Owners of both relays end up using them for the same kind of project: dry contact wiring for garage doors, gates and boiler call-for-heat lines, with Home Assistant as the usual brain. Aqara Dual Relay Module T2 owners single out the external antenna that holds a signal inside a metal fan canopy or grounded box, and the two channels that split a fan from its light, while they complain about a body larger than single-channel modules, screw terminals that need reseating and a few units that would not pair. Shelly 1 Mini Gen4 owners single out how small it is, instant local control and the way it keeps the wall switch working, and they mention tiny printed instructions, a plastic-faceplate requirement in metal boxes, no UL or ETL listing and a few units that arrived dead or dropped offline after months.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
