It adds Wi-Fi, Bluetooth, Zigbee and Matter in one module, plus dry-contact mode and a 3-year warranty against the Aqara Single Switch Module T1 (No Neutral)'s 1-year cover. It also handles a heavier resistive load, 2000W and 8A against 1250W and 5A, and needs no hub at all for its core Wi-Fi and Matter control. The Aqara Single Switch Module T1 (No Neutral) answers with the one thing the Shelly cannot do: install in a wall box that has no neutral wire, and it confirms power-off memory where the Shelly's is undocumented. Both are single-channel and reach Google Home, Alexa, Apple HomeKit and Home Assistant. Pick the Shelly 1 Mini Gen4 when you have a neutral and want multi-protocol flexibility; pick the Aqara Single Switch Module T1 (No Neutral) specifically when that wire is missing.

What the differences mean

Neutral wire

The Aqara Single Switch Module T1 (No Neutral) is built to install without a neutral wire. The Shelly 1 Mini Gen4 needs both line and neutral.

Load rating

The Shelly 1 Mini Gen4 handles resistive loads up to 2000W at 8A. The Aqara Single Switch Module T1 (No Neutral) is limited to 1250W at 5A.

Radios and hub

The Shelly 1 Mini Gen4 combines Wi-Fi, Bluetooth, Zigbee and Matter, and needs no hub for its Wi-Fi and Matter control. The Aqara is Zigbee-only and needs an Aqara hub for everything, including Matter.

Dry contact mode

The Shelly 1 Mini Gen4 offers dry-contact mode, useful for a garage door opener or a boiler trigger. The Aqara Single Switch Module T1 (No Neutral) does not support it.

Warranty

The Shelly 1 Mini Gen4 carries a 3-year warranty against the Aqara Single Switch Module T1 (No Neutral)'s 1 year.

Which one to buy if

What owners say

Owners of the Shelly 1 Mini Gen4 keep returning to its size: several say it fits switch and fixture boxes where a standard relay will not, which is exactly why they chose the Mini over a full-size unit. They also praise the local control that keeps automations working without the internet, the dry contacts for projects like a garage door opener or a pool light on an existing timer, and that it preserves the manual switch behind it. Their warnings are about wiring rather than performance: it needs both line and neutral, a metal box needs a plastic faceplate or the signal is blocked, and this model is not UL or ETL listed. A few units have arrived dead or lost connectivity after a few months.

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