Aqara Single Switch Module T1 (No 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
The Shelly 1PM Gen4 wins this smart relay comparison by packing more into one no-neutral module: multi-protocol connectivity (Wi-Fi, Bluetooth, Zigbee and Matter), built-in energy monitoring, dry-contact mode and a Zigbee router role, all rated to 16A. The Aqara Single Switch Module T1 (No Neutral) holds real ground as the more affordable pick with a fuller stated safety spec (overheating protection is confirmed) and power-off memory, plus HomeKit and IFTTT support that fits Zigbee households. Both run without a neutral wire and reach Google Home, Alexa, Apple HomeKit and Home Assistant, so either can retrofit a no-neutral box. Pick the Shelly 1PM Gen4 if you want power metering, protocol flexibility and dry-contact triggering with the higher load ceiling; pick the Aqara Single Switch Module T1 (No Neutral) if you want the cheaper Zigbee module with power-off memory and do not need energy data or dry contacts.

Frequently Asked Questions

Which is better overall: Aqara Single Switch Module T1 (No Neutral) or Shelly 1PM Gen4?

The Shelly 1PM Gen4 is better overall, adding built-in energy monitoring, Wi-Fi, Bluetooth, Zigbee and Matter connectivity, dry-contact mode, a Zigbee router role and a 16A rating. The Aqara Single Switch Module T1 (No Neutral) counters as the cheaper option with confirmed overheating protection and power-off memory.

What is the biggest difference between the Aqara Single Switch Module T1 (No Neutral) and the Shelly 1PM Gen4?

Energy monitoring and connectivity. The Shelly 1PM Gen4 measures instant power, voltage and total consumption and carries four radios plus dry-contact mode, while the Aqara is a Zigbee-only module (hub required) with no energy monitoring and wet-contact wiring only. Notably, both install without a neutral wire.

Does either relay measure power consumption?

Only the Shelly 1PM Gen4. Its precise power metering tracks instant power, voltage and total consumption, which is ideal for watching an appliance like a water heater. The Aqara Single Switch Module T1 (No Neutral) has no energy monitoring, so choose the Shelly if consumption data matters.

Do both relays work without a neutral wire?

Yes. Both the Aqara Single Switch Module T1 (No Neutral) and the Shelly 1PM Gen4 are designed to run without a neutral wire, so either can go into a no-neutral box. The decision then comes down to metering, connectivity and price rather than wiring.

Who should buy the Aqara Single Switch Module T1 (No Neutral)?

Buy it if you want the more affordable no-neutral relay with confirmed overheating protection and power-off memory, and you run a Zigbee or Aqara ecosystem with HomeKit and IFTTT. It is a clean fit for switching lights where energy data is not needed.

Who should buy the Shelly 1PM Gen4?

Buy the Shelly 1PM Gen4 if you want to both control and measure a circuit, need the higher 16A rating, and value multi-protocol connectivity, dry-contact triggering and a Zigbee router, all without a neutral wire.
