Lutron Caseta Diva Smart Dimmer Switch vs NodOn Battery-free Zigbee Wall Switch

Zigbee Green Power (Generic Switch) transmitter, so it needs a Green Power capable coordinator such as Zigbee2MQTT. ZHA does not handle Green Power. | Zigbee Green Power device, not a Zigbee router.

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

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

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 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

Wireless and battery-free: each press harvests its own energy and sends a Zigbee Green Power command (four buttons, primary channels 15, 11, 20 and 25). No wiring and no mains load is switched.

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

Scene controllers are not Alexa endpoints: the button presses are handled by the Zigbee gateway and only the devices they control show up in Alexa

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

Not compatible with Google Home.

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

Compatible with Home Assistant through Zigbee2MQTT only. ZHA does not support Zigbee Green Power, which this switch uses.

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

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

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

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

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

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

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
