It switches two circuits at 2500 W and 10 A each, reports energy use, adds interlock mode and acts as a Zigbee router that strengthens the mesh, while the Shelly 1 Mini Gen3 has one 2000 W, 8 A channel and no monitoring or protections beyond overheating. Where the Shelly 1 Mini Gen3 pulls ahead is convenience: it is a Wi-Fi device with no hub, a body of 29 x 35 x 16 mm, a 3 year warranty and Matter support, and it lists Alexa, Google Home, Apple Home, SmartThings and Home Assistant directly. Both need a neutral wire and both support dry and wet contact wiring. Pick the Aqara Dual Relay Module T2 for a Zigbee setup with two loads, and the Shelly 1 Mini Gen3 for a hub-free retrofit of a single light or gate.

What the differences mean

Circuits per module

The Aqara Dual Relay Module T2 has two independent channels, enough for a fan and its light. The Shelly 1 Mini Gen3 has one, so the same job takes two modules and two places to hide them.

Load rating

The Aqara Dual Relay Module T2 is rated 2500 W and 10 A resistive per channel, the Shelly 1 Mini Gen3 2000 W and 8 A. For heavier loads such as a small heater or a bank of lights, the Aqara has more room before you need a contactor.

Protections and energy monitoring

The Aqara Dual Relay Module T2 documents overvoltage, overcurrent and overpower protection as well as overheating, and it measures energy use. The Shelly 1 Mini Gen3 lists overheating protection only and has no energy monitoring.

Hub or no hub

The Shelly 1 Mini Gen3 joins 2.4 GHz Wi-Fi by itself, using Bluetooth only for pairing. The Aqara Dual Relay Module T2 is Zigbee only and needs a hub, and an Aqara hub for Alexa, Google Home, Apple Home and Matter. In return it repeats the Zigbee signal for other devices, which the Shelly cannot do.

Size and warranty

The Shelly 1 Mini Gen3 is 29 x 35 x 16 mm against 45.5 x 48 x 24 mm and carries a 3 year warranty against 1 year. It is the easier one to fit into a shallow box and the one with the longer coverage.

What owners say

Owners of both relays like the same trick: dry contacts that turn a garage door, a gate or a boiler call-for-heat line into something a phone or Home Assistant can trigger. Aqara Dual Relay Module T2 owners single out the external antenna that keeps a signal alive inside metal boxes, and two circuits from one module, while they mention a body bigger than single-channel relays, screw terminals that need reseating and the odd unit that would not pair. Shelly 1 Mini Gen3 owners talk about size and value, installs that take about ten minutes and instant local response, and their most repeated complaint is a misleading wiring diagram, where the I and O terminals are the relay contacts and not a power output, so first-timers often look for a video guide before it works.

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.
