Quick verdict
The no-frills sibling of the ZW6HD dimmer. If you just need on/off control for a light, fan, or other load, this is a dependable Z-Wave switch from a brand that has been making electrical hardware forever. It looks like a standard Decora paddle, works fully local via Z-Wave JS in Home Assistant, and requires zero cloud. Simple, reliable, boring in the best way. Neutral wire required.
Standout: No-nonsense Z-Wave on/off switch with Leviton's commercial-grade reliability.
