Frequently Asked Questions
Which is better overall, the Aqara Single Switch Module T1 (No Neutral) or the Shelly 2PM Gen3?
The Aqara Single Switch Module T1 (No Neutral) is the stronger overall pick in this pairing, thanks to a lower price, an overheating protection cutoff, broader confirmed integrations, power-off memory and wet-contact wiring. The catch is that it is a single-channel Zigbee module that needs a hub, so buyers who want two circuits or energy metering may still prefer the Shelly 2PM Gen3.
What is the biggest difference between the Aqara Single Switch Module T1 (No Neutral) and the Shelly 2PM Gen3?
It comes down to structure and protocol. The Aqara Single Switch Module T1 (No Neutral) is a single-channel Zigbee device that installs without a neutral wire, while the Shelly 2PM Gen3 is a two-channel Wi-Fi and Matter relay that requires a neutral and adds per-channel energy monitoring plus a cover mode for shutters.
Can either relay be installed without a neutral wire?
Only one. The Aqara Single Switch Module T1 (No Neutral) is designed to work in boxes that have no neutral wire, which is its main selling point. The Shelly 2PM Gen3 requires a neutral connection at the install point.
Which one tracks energy usage?
The Shelly 2PM Gen3 includes built-in power metering on each of its two channels, so you can monitor consumption per circuit. The Aqara Single Switch Module T1 (No Neutral) does not offer energy monitoring.
Who should buy the Aqara Single Switch Module T1 (No Neutral)?
Anyone on an Aqara or Zigbee hub who wants to make a single circuit smart cheaply, especially in an older switch box with no neutral wire. It also adds power-off memory, a physical button and an overheating cutoff that the Shelly 2PM Gen3 leaves unconfirmed.
Who should buy the Shelly 2PM Gen3?
Buyers who need to control two independent circuits or a roller shutter, blind or gate from one module, and who want per-channel energy monitoring over Wi-Fi and Matter. The Shelly 2PM Gen3 does need a neutral wire, so confirm your wiring first.
