Both modules include a full four-way safety suite (overheating, overvoltage, overcurrent and overpower protection) and built-in energy monitoring, but they are built differently: the Aqara is a one-channel Zigbee device that needs a hub and also acts as a Zigbee router, extending your mesh, while the Shelly 2PM Gen3 is a two-channel Wi-Fi and Matter relay with an interlock/cover mode for roller shutters and blinds. The Aqara Single Switch Module T1 (With Neutral) answers back on price, since it costs less. Choose the Aqara Single Switch Module T1 (With Neutral) for a single safety-rich circuit that also strengthens a Zigbee mesh; choose the Shelly 2PM Gen3 when you need two channels or Wi-Fi/Matter cover control.

What the differences mean

Channel count

The Shelly 2PM Gen3 switches two independent circuits. The Aqara Single Switch Module T1 (With Neutral) is single-channel, controlling one circuit.

Zigbee mesh role

The Aqara Single Switch Module T1 (With Neutral) acts as a Zigbee router, repeating the mesh for other Zigbee devices. The Shelly 2PM Gen3 has no Zigbee radio at all, so it does not extend any Zigbee mesh.

Cover and interlock mode

The Shelly 2PM Gen3 has an interlock/cover mode for driving roller shutters, blinds and gates. The Aqara Single Switch Module T1 (With Neutral) has no such mode, it only switches its one circuit on or off.

Price

The Aqara Single Switch Module T1 (With Neutral) costs less than the Shelly 2PM Gen3.

Which one to buy if

What owners say

Owners of the Shelly 2PM Gen3 highlight two things above all: how compact it is for what it does, and stable Wi-Fi that keeps working long after installation, even inside a crowded wall box. Several German-speaking owners specifically describe swapping out an aging Rolladen roller shutter actuator for the Shelly's interlock mode and folding it straight into Home Assistant, where they call the integration flawless and fully local. Their complaint is a rockier first-time pairing over Wi-Fi for a vocal minority, including one buyer who struggled specifically to add it to Alexa, and a Gen3 casing that is a touch thicker than the previous generation.

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.

Frequently Asked Questions

Which is better overall, the Aqara Single Switch Module T1 (With Neutral) or the Shelly 2PM Gen3?

The Shelly 2PM Gen3 wins this pairing on rating, warranty and channel count. The Aqara Single Switch Module T1 (With Neutral) remains the cheaper single-channel option, and it is the one that doubles as a Zigbee router.

Can the Shelly 2PM Gen3 control a Rolladen roller shutter through Home Assistant?

Yes. Its interlock/cover mode is built for bi-directional shutter, blind and gate motors, and it works with Home Assistant, which owners describe as a fully local integration. The Aqara Single Switch Module T1 (With Neutral) has no equivalent cover mode.

What is the biggest difference between the Aqara Single Switch Module T1 (With Neutral) and the Shelly 2PM Gen3?

Channel count and protocol. The Aqara Single Switch Module T1 (With Neutral) is a single-channel Zigbee module (hub required) that also acts as a Zigbee router, whereas the Shelly 2PM Gen3 is a two-channel Wi-Fi and Matter relay with an interlock/cover mode for motorized shutters and gates. Both include energy monitoring.

Do both of these relays offer energy monitoring?

Yes. The Aqara Single Switch Module T1 (With Neutral) and the Shelly 2PM Gen3 both track energy use. The Shelly measures it per channel across its two circuits, while the Aqara meters its single circuit.

Who should buy the Aqara Single Switch Module T1 (With Neutral)?

Owners of an Aqara or Zigbee hub who want a single circuit made smart with strong safety protection and a module that doubles as a Zigbee repeater. It requires a neutral wire, so check your box.

Who should buy the Shelly 2PM Gen3?

Anyone needing to switch two circuits or automate a roller shutter, blind or gate from one module over Wi-Fi and Matter, with per-channel energy monitoring. It is the better fit for Apple Home, Google Home and Alexa users who want Matter rather than a Zigbee hub.
