Leviton Decora Smart Wi-Fi Switch D315S vs Lutron Caseta Diva Smart Dimmer Switch

Leviton's network specification is 2.4 GHz only

This is the Wi-Fi model; Leviton's Z-Wave switches are a separate Decora Smart line

The LED can be set to light when the load is on, when the load is off (the default) or to stay off, from the My Leviton app or the switch's own setup mode

Lutron documents that the Diva's status LED can be switched on or off from the Lutron app (it is on by default), and the same screen adjusts the dimmer's high-end and low-end trim

Schedules with sunrise and sunset triggers, room scenes, activities and an auto-shutoff timer in the My Leviton app, with schedules stored on the device so they keep running during an internet outage

Scenes, schedules, geofencing and Smart Away from the Lutron app, plus up to 10 Pico remotes or Caseta motion sensors paired directly to the dimmer with no hub at all

Onboard memory keeps the configuration and the schedules, and the switch returns to its last state when power is restored

Power failure memory: should power be interrupted, the control returns to the level it was set to before the interruption

Status LED that illuminates when the lights are off so the switch is easy to find in the dark, and reports connectivity and device status

A white soft-glow light bar runs beside the slider and shows the light level, which is what makes the dimmer readable in a dark room

The switch is wired to the load it controls; the wire-free half of the system is the separate Decora Smart Anywhere Companion (DAWSC)

The dimmer is wired to the load it controls; the wire-free half of the system is the separate Pico remote or the Claro accessory switch

Load rating of 120VAC, 60Hz

Operating voltage 120 V~ 50/60 Hz, listed for the DVRF-6L in Lutron's Caseta load controls specification submittal

Leviton's ratings chart lists LED/CFL loads up to 3A alongside the 15A general use and 1/3 HP motor ratings

Dimmable CFL up to 150 W, listed alongside LED in the derating chart of the Diva's own installation guide

Rated for motor loads up to 1/3 HP, so it can switch ceiling fans, exhaust fans and pumps

Dimmable LED rated for 120 V~, up to 150 W with Lutron's LED+ forward-phase dimming

Rated 15A general use at 120VAC, which covers incandescent and other general purpose loads

Incandescent and halogen loads, 25 W minimum and 600 W maximum when the dimmer is not ganged

An overload is caught by the thermal protection rather than by a separate power cutoff, so exceeding the wattage rating is prevented by the derating chart, not by the dimmer

Lutron documents surge withstand testing to IEEE C62.41-1991, which is immunity rather than a protective cutoff, and claims no overvoltage protection function
