Leviton Decora Smart Wi-Fi Switch D315S vs TP-Link Kasa HS200

The TP-Link Kasa HS200 wins on price, owner track record and a 2 year warranty, so it is the value pick. The Leviton Decora Smart Wi-Fi Switch D315S wins on connectivity and integrations: it is Matter certified, carries Bluetooth and supports Apple Home. Which one is better depends on whether you need Matter.

The Leviton Decora Smart Wi-Fi Switch D315S is Matter certified and supports Apple Home, so Siri controls it after commissioning. The TP-Link Kasa HS200 supports neither, but it works with Google Home, Alexa, SmartThings and Home Assistant.

The Leviton Decora Smart Wi-Fi Switch D315S is rated for a 1/3 HP motor, against 1/6 HP for the TP-Link Kasa HS200. Both are rated for 15A general use, and neither dims.

Neither the Leviton Decora Smart Wi-Fi Switch D315S nor the TP-Link Kasa HS200 needs a hub: both join 2.4 GHz Wi-Fi directly. Both require a neutral wire in the wall box, and both are single-pole on/off switches that cannot replace a 3-way circuit.

The Leviton Decora Smart Wi-Fi Switch D315S keeps its configuration and schedules in onboard memory and returns to its last state when power comes back, and its schedules keep running while the internet is down. The TP-Link Kasa HS200 does not document a power-off memory setting.

Buy the TP-Link Kasa HS200 for the cheaper hub-free switch with a 2 year warranty in an Alexa, Google or SmartThings home. Buy the Leviton Decora Smart Wi-Fi Switch D315S for Matter and Apple Home support, a wider motor rating or a slim fit in a crowded box.
