Aqara Single Switch Module T1 (No Neutral) vs Shelly 1 Mini Gen4

The Shelly 1 Mini Gen4 is the stronger overall pick, adding a 3-year warranty, Wi-Fi, Bluetooth, Zigbee and Matter connectivity, dry-contact mode and a Zigbee router role. The Aqara Single Switch Module T1 (No Neutral) wins when you have no neutral wire or want the cheaper option with power-off memory.

The Aqara installs without a neutral wire while the Shelly 1 Mini Gen4 requires one. They also differ on radios (the Shelly adds Wi-Fi, Bluetooth and Matter to Zigbee and needs no hub for core control) and on contact type, since only the Shelly offers dry-contact mode.

The Shelly 1 Mini Gen4, rated to 2000W and 8A on resistive loads against 1250W and 5A for the Aqara Single Switch Module T1 (No Neutral). Both are still light-duty modules, so check the current rating against your circuit; neither is a heavy-duty 16A unit like the full-size Gen4.

The Aqara is a Zigbee module that requires an Aqara hub and uses it for HomeKit and Matter. The Shelly 1 Mini Gen4 needs no hub for Wi-Fi and Matter control, though using it over Zigbee does require a Zigbee hub, so it is more flexible if you would rather avoid a dedicated coordinator.

Buy it if your switch box has no neutral wire, you run a Zigbee or Aqara setup with HomeKit, and you want the more affordable relay with power-off memory for basic switching, staying within its 1250W and 5A resistive limit.

Buy the Shelly 1 Mini Gen4 if you need the smallest possible module for a crowded box, have a neutral wire, and want multi-protocol connectivity, dry-contact triggering, a Zigbee router and a 3-year warranty.
