A summary of selected recorded differences between these wall switches. Check the full specification table below for details and conditions.

Feature differences among your selected devices

Wireless Switch Mode (features): Lutron Caseta Diva Smart Dimmer Switch — No (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); Sonoff Orb-ZBW2 Zigbee Double Smart Wall Switch — Yes (Detach Relay Mode separates the physical switch from the relay output, so the paddle can trigger a Smart Scene or leave a smart bulb downstream powered.).
Capacitive Load (power): Lutron Caseta Diva Smart Dimmer Switch — Yes (Dimmable CFL up to 150 W, listed alongside LED in the derating chart of the Diva's own installation guide); Sonoff Orb-ZBW2 Zigbee Double Smart Wall Switch — No (The rating is stated for resistive loads only, with no capacitive load rating published.).
Inductive Load (power): Lutron Caseta Diva Smart Dimmer Switch — Yes (Dimmable LED rated for 120 V~, up to 150 W with Lutron's LED+ forward-phase dimming); Sonoff Orb-ZBW2 Zigbee Double Smart Wall Switch — No (The rating is stated for resistive loads only, with no inductive load rating published.).
Neutral Required (power): Lutron Caseta Diva Smart Dimmer Switch — No (Simple two-wire installation, so no neutral wire is needed in the wallbox); Sonoff Orb-ZBW2 Zigbee Double Smart Wall Switch — Yes (SONOFF's FAQ answers it directly: the Orb-ZBW2 requires a neutral wire for proper installation and operation.).

Specifications to check side by side

Zigbee (connectivity): Lutron Caseta Diva Smart Dimmer Switch — No; Sonoff Orb-ZBW2 Zigbee Double Smart Wall Switch — Zigbee Hub required (Built on Zigbee 3.0 with an EFR32MG21 MCU. It also acts as a Zigbee router, repeating the mesh for other devices, but it still needs a coordinator to join.).
