Aqara Single Switch Module T1 (With Neutral) vs Shelly 2PM Gen4

Full Smart Relays comparison in 2026

Updated July 2026
Data from Amazon and official Aqara and Shelly sites.
2026 verdict
The Aqara Single Switch Module T1 (With Neutral) takes this smart relay comparison, mainly on value and simplicity: it is the more affordable pick, it confirms power-off memory, and it matches the Shelly 2PM Gen4 where it counts with energy monitoring, full four-way safety protection and a Zigbee router role. The Shelly 2PM Gen4 is the more ambitious hardware, though, with two independent 16A channels, per-channel energy metering, an interlock/cover mode for roller shutters and blinds, multi-protocol connectivity (Wi-Fi, Bluetooth, Zigbee and Matter) and a 3-year warranty. Both reach Google Home, Alexa, Apple HomeKit and Home Assistant and both need a neutral wire. Choose the Aqara Single Switch Module T1 (With Neutral) when you only need to switch one circuit and want the cheaper metered module; choose the Shelly 2PM Gen4 when you need two channels or shutter automation.
