Aqara Single Switch Module T1 (With Neutral) vs Shelly 1PM Gen4

Full Smart Relays comparison in 2026

Updated September 2026
Data from Amazon and official Aqara and Shelly sites.
2026 verdict
In this smart relay comparison the Aqara Single Switch Module T1 (With Neutral) comes out ahead, winning on price and on safety with its full four-way protection (overheating, overvoltage, overcurrent and overpower), while also matching the Shelly on the things that usually decide a relay: it includes energy monitoring, power-off memory and a Zigbee router role. The Shelly 1PM Gen4 still has meaningful advantages, namely broader connectivity (Wi-Fi, Bluetooth, Zigbee and Matter in one module, no hub needed for core control), dry-contact mode and installation without a neutral wire, plus a higher 16A rating. Both track energy, act as Zigbee routers and reach Google Home, Alexa, Apple HomeKit and Home Assistant. Choose the Aqara Single Switch Module T1 (With Neutral) for the cheaper, safety-loaded metered module in a Zigbee home; choose the Shelly 1PM Gen4 if you need no-neutral wiring, dry contacts, the higher load ceiling or multi-protocol flexibility.

Frequently Asked Questions

Which is better overall: Aqara Single Switch Module T1 (With Neutral) or Shelly 1PM Gen4?

The Aqara Single Switch Module T1 (With Neutral) is better overall as the cheaper module with full four-way safety protection, and it matches the Shelly on energy monitoring and Zigbee routing. The Shelly 1PM Gen4 wins for no-neutral installs, dry-contact mode, a 16A rating and multi-protocol connectivity.

What is the biggest difference between the Aqara Single Switch Module T1 (With Neutral) and the Shelly 1PM Gen4?

Both include energy monitoring, so the split is elsewhere: the Aqara requires a neutral and offers full safety protection at a lower price, while the Shelly 1PM Gen4 installs without a neutral, adds dry-contact mode and multiple radios, and is rated to 16A.

Do both relays measure energy consumption?

Yes. Both the Aqara Single Switch Module T1 (With Neutral) and the Shelly 1PM Gen4 include energy monitoring, so consumption tracking is not the deciding factor. The choice comes down to wiring, dry contacts, load rating, connectivity and price.

Which one works without a neutral wire and supports dry contacts?

The Shelly 1PM Gen4 does both: it installs without a neutral wire and supports dry-contact mode for triggering external devices. The Aqara Single Switch Module T1 (With Neutral) requires a neutral and uses wet-contact wiring only.

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

Buy it if you have a neutral wire and want the cheaper metered module with full overheating, overvoltage, overcurrent and overpower protection, power-off memory and a Zigbee router, ideally in a Zigbee or Aqara ecosystem with HomeKit.

Who should buy the Shelly 1PM Gen4?

Buy the Shelly 1PM Gen4 if you need no-neutral installation, dry-contact triggering, a 16A rating or multi-protocol connectivity across Wi-Fi, Bluetooth, Zigbee and Matter, all with energy monitoring built in.
