The Gen 1 Dimmer Toggle Switch with Scenes (NZW31-ST) is a discontinued Z-Wave Plus in-wall dimmer in a toggle body rather than a paddle, with multi-tap scene reporting. Z-Wave JS still drives it locally.

Discontinued, and the toggle counterpart to the NZW31-S: no later Inovelli generation offers a toggle body, so a house standardized on toggles keeps these or converts to paddles. Mandatory neutral, 500W incandescent single-gang derating to 400W double and 300W triple, and central scene reporting for multi-tap. Z-Wave JS lists it as NZW31T. No retail page remains; the manual lives on the Inovelli help center.
