It switches two independent circuits, monitors energy on each, offers full overheating, overvoltage, overcurrent and overpower protection, and adds an interlock or cover mode for roller shutters and garage doors, over Wi-Fi and Bluetooth with no hub. The Aqara Single Switch Module T1 (No Neutral) answers the one thing the Shelly cannot: it installs in a wall box that has no neutral wire, and it brings Apple HomeKit and Matter through an Aqara hub. Pick the Aqara Single Switch Module T1 (No Neutral) for a single light circuit in a box without a neutral, and the Shelly Plus 2PM for dual circuits, metering or motors in a box that has both wires.

What the differences mean

Neutral wire

The Aqara Single Switch Module T1 (No Neutral) is built for wall boxes that lack a neutral, so it can be installed where most relays cannot. The Shelly Plus 2PM needs both a live and a neutral wire at the install point, which rules it out of older switch boxes without one.

Relay channels

The Shelly Plus 2PM controls two circuits from one unit, which is what lets it drive a motor in both directions or switch two lights. The Aqara Single Switch Module T1 (No Neutral) has a single channel, so it handles one circuit.

Energy monitoring

The Shelly Plus 2PM measures consumption per channel, so each connected circuit reports its own usage. The Aqara Single Switch Module T1 (No Neutral) has no metering at all, which is one of the features its no-neutral design gives up.

Protocol and hub

The Aqara Single Switch Module T1 (No Neutral) runs on Zigbee and needs a hub, with Matter and HomeKit arriving through an Aqara hub. The Shelly Plus 2PM joins 2.4 GHz Wi-Fi and Bluetooth directly, needs no hub, and works with Google Home, Alexa, SmartThings and Home Assistant.

Safety protections

The Shelly Plus 2PM carries overheating, overvoltage, overcurrent and overpower protection. The Aqara Single Switch Module T1 (No Neutral) keeps only overheating protection, so it gives up the other three cut-offs.

Cover and interlock mode

The Shelly Plus 2PM includes an interlock or cover mode for roller shutters, awnings, gates and other bi-directional motors. The Aqara Single Switch Module T1 (No Neutral) has no interlock or cover mode, so motorised blinds are not its job.

What owners say

Shelly Plus 2PM owners keep coming back to reliability, and many say they own several or dozens of Shelly devices that have run for years without failing. They single out the cover and interlock mode for roller shutters, curtains and garage doors, which turns a plain wall switch into precise up and down control, and they value running the whole thing locally through Home Assistant with no cloud account. Their warnings are practical: the relay needs a live and a neutral wire, which some older light switch boxes do not have, and a few mention the unit running warm or missing any built-in position feedback for a shutter. Energy monitoring per channel rounds out what they rely on.

Frequently Asked Questions

Which is better overall: Aqara Single Switch Module T1 (No Neutral) or Shelly Plus 2PM?

The Shelly Plus 2PM, unless your box has no neutral wire. It switches two circuits with energy monitoring and full protection over Wi-Fi with no hub. The Aqara Single Switch Module T1 (No Neutral) wins only when the missing neutral is the obstacle, and it is a single channel without metering.

What is the biggest difference between the Aqara Single Switch Module T1 (No Neutral) and the Shelly Plus 2PM?

The wiring and the channel count. The Aqara Single Switch Module T1 (No Neutral) installs without a neutral in one circuit, while the Shelly Plus 2PM needs live and neutral and controls two circuits with per-channel energy monitoring.

Does the Shelly Plus 2PM need a neutral wire?

Yes. The Shelly Plus 2PM requires both a live and a neutral wire at the install point, which some older switch installations do not have. If that wire is missing, the Aqara Single Switch Module T1 (No Neutral) is the one designed for the job.

Which one works with Apple HomeKit?

The Aqara Single Switch Module T1 (No Neutral), through an Aqara hub, which is also how it reaches Matter. The Shelly Plus 2PM does not support HomeKit, working with Google Home, Alexa, SmartThings and Home Assistant instead.

Anyone whose wall box has no neutral wire, or who wants a single light circuit on Apple HomeKit and Matter through a Zigbee hub.
