The Gen 1 Dimmer Switch (NZW31) is a discontinued Z-Wave Plus in-wall dimmer with a paddle and a status LED, no scene control and no energy reporting. Z-Wave JS still drives it locally.
Discontinued and two generations behind. Z-Wave Plus at 908.42 MHz with a mandatory neutral, and the load derates by gang: 500W incandescent single-gang, 400W double, 300W triple. No LED bar, no scene support and no energy reporting on this variant, so Home Assistant gets a dimmable light entity and nothing else. Still repeats the Z-Wave mesh. No retail page remains; the manual lives on the Inovelli help center.
