2026 verdict
For a two-gang box without a neutral, the Aqara Smart Wall Switch (No Neutral) - Double is the more practical of these two because it drives two separate circuits from one plate.
It is also the more affordable, and once paired with an Aqara hub it reaches every major platform as well as Matter through that hub. The Lutron Caseta Diva Smart Dimmer Switch answers with what the Aqara cannot do: it dims, it carries overheat protection, and owners rate it higher for long-term reliability. The cost of that is a single dimmed circuit, a required Lutron Smart Hub and no Matter path. Buy the Aqara when two circuits matter; buy the Lutron when one dimmable circuit and proven reliability matter more.

What the differences mean
Two circuits or one
The Aqara Smart Wall Switch (No Neutral) - Double packs two independent switches into a single plate, so it can run two lights, or a light and a bathroom fan, from one box. The Lutron Caseta Diva Smart Dimmer Switch is a single control, so a two-circuit install would need a second dimmer and a second box.
Dimming
The Lutron Caseta Diva Smart Dimmer Switch dims incandescent and halogen up to 600 W and dimmable LED or CFL up to 150 W. The Aqara Smart Wall Switch (No Neutral) - Double only switches on and off, so a fixture that needs variable brightness is not something it can handle.
Safety protection
The Lutron Caseta Diva Smart Dimmer Switch includes Over Temperature Protection, which drops the load and blinks the light bar when the dimmer runs too hot. The Aqara Smart Wall Switch (No Neutral) - Double lists no overheating, overvoltage, overcurrent or overpower cutoff at all, leaving protection to the branch circuit breaker.
Hub and platforms
Both rely on a hub. The Aqara reaches Google Home, Alexa, Apple HomeKit, SmartThings and Home Assistant through an Aqara hub and adds Matter through that hub, while pairing directly with SmartThings over Zigbee. The Lutron Caseta Diva Smart Dimmer Switch reaches its five platforms through the Lutron Smart Hub and has no Matter certification.
Load and region
The Aqara Smart Wall Switch (No Neutral) - Double is a US 120 V switch rated for 600 W resistive, 200 W capacitive and inductive loads, in a 120 x 74 x 36.5 mm body. The Lutron Caseta Diva Smart Dimmer Switch is a 120 V US Decora dimmer rated for 600 W of incandescent or halogen in a 119 x 75 x 30 mm body.
Which one to buy if
- the wall plate controls two separate lights or circuits
The Aqara Smart Wall Switch (No Neutral) - Double has two independent rockers, so one box covers both loads.
- you need a dimmer for a single fixture
The Lutron Caseta Diva Smart Dimmer Switch dims the circuit, which the Aqara cannot do.
- your home already runs on Aqara or Zigbee
The Aqara Smart Wall Switch (No Neutral) - Double drops straight into an existing Zigbee setup.
- long-term reliability is the top priority
The Lutron Caseta Diva Smart Dimmer Switch is the better reviewed and adds overheat protection the Aqara lacks.
- you want one button to trigger scenes instead of a wired load
The Aqara Smart Wall Switch (No Neutral) - Double supports wireless switch mode on its rockers.

What owners say
Aqara Smart Wall Switch (No Neutral) - Double owners describe the same easy swap: pull the old switch, wire the Aqara in a few minutes with no neutral needed, then pair it to an Aqara hub and into Home Assistant, Alexa or Apple Home. They value the wireless switch mode that lets the second button run a scene instead of a load, and several praise support when a unit failed under warranty. Their gripes are the soft, mushy button feel, the reliance on an Aqara hub, and the missing overheating and overcurrent protection. Lutron Caseta Diva Smart Dimmer Switch owners, by contrast, talk about years of uninterrupted service, a paddle guests can use without a lesson, and an ecosystem that holds up when the internet drops, with cost and the separate hub as their main complaints.
