Where you'd use it
Motorised blind position control
Drive a roller blind, awning or curtain motor with proper open/closed position tracking, so you can set it to a precise 40% open rather than just fully up or down.
Dual-circuit switching with metering
Control two independent circuits u2014 say hallway and landing lighting u2014 from one device, each with its own power measurement, instead of fitting two separate single-channel relays.
Retrofit into a double gang box
Fit it behind a two-gang light switch where a single relay wouldn't cover both switched circuits, using the embedded web interface to configure it without the cloud app if needed.
