How they stack up

Leviton Decora Smart Wi-Fi Switch D215S

The best Matter on/off switch. It adds the Matter and HomeKit support the Kasa HS200 lacks and the modern look the Lutron Caséta Smart Dimmer PD-6WCL misses, while staying hub-free. Like the Kasa it requires a neutral wire (unlike the no-neutral Lutron and GE CYNC dimmer), and unlike the TP-Link Tapo S505D it's on/off rather than a dimmer.

TP-Link Tapo S505D

The budget Matter dimmer. It's the only dimmer here besides the premium Lutron Caséta Smart Dimmer PD-6WCL, and it undercuts it dramatically while adding Matter the Lutron lacks. It adds dimming the on/off Kasa HS200 and Leviton Decora Smart D215S don't have, but like them it requires a neutral wire the GE CYNC dimmer doesn't.
