Lutron Caseta Diva Smart Dimmer Switch

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

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

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

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

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

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

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

600 W single gang, derated to 500 W in a double gang and 400 W in a triple gang wallbox

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

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

Simple two-wire installation, so no neutral wire is needed in the wallbox

The dimmer reaches the Lutron Smart Hub, Pico remotes and Caseta motion sensors over Lutron's own Clear Connect RF rather than Wi-Fi, which is why the lights keep responding when the router is down

Lutron lists Google Assistant among the platforms Caseta works with, through the Lutron Smart Hub

Lutron lists Amazon Alexa among the platforms Caseta works with, through the Lutron Smart Hub

Lutron lists Apple Home among the platforms Caseta works with; the Apple Home technology sits in the smart hub, so Siri controls the dimmer once it is paired to one

Lutron lists Samsung SmartThings among the platforms Caseta works with, through the Lutron Smart Hub

The core Lutron Caseta integration connects to the Lutron Caseta Smart Hub (L-BDG2-WH) and exposes wall dimmers as lights

The CSA certified-product database holds no Matter certification for Lutron (only three Zigbee 3.0 Aurora dimmers), and Lutron's own Caseta compatibility page never mentions Matter

The dimmer has an Over Temperature Protection (OTP) mode: it drops the load and blinks the light bar four times when it runs too hot, typically after being overloaded or ganged without derating

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

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
