Quick verdict
Ceiling fan automation done right. Four speed levels controlled via Z-Wave mean you can tie fan speed to temperature sensors in Home Assistant. Cool the bedroom automatically when it gets warm at night. It is a proper fan controller, not a dimmer pretending to be one, so it will not damage your fan motor. Matches the rest of the Leviton Decora line visually. AC motor fans only, so check before you buy. Neutral wire required.
Standout: 4-speed Z-Wave ceiling fan controller in a standard Decora paddle form factor.

Local control facts
Home Assistant: zwave_js integration, Local Push (home-assistant.io, checked Oct 10, 2026)
Z-Wave JS: in the device database, listed as Leviton ZW4SF (4 Speed Fan Controller) (github.com, checked Oct 22, 2026)
Why it stands out
4-speed fan control from a wall switch, replacing pull chains with smart automation
Z-Wave means fully local control with no cloud dependency
Decora paddle design matches Leviton's dimmer and switch lineup for a consistent look
Reasons to hesitate
Leviton rates it only for overhead paddle fans without electronic control, up to a 1.5 A motor load, and says it is not for exhaust-type fans, lighting loads, or combined ceiling fan light kits; it is an AC-motor control, not a DC one
requires a Z-Wave controller for Home Assistant integration
neutral wire required, so verify your wiring before purchasing
Best for
automating ceiling fan speed based on temperature or time of day in Home Assistant
replacing pull-chain fan controls with a clean wall switch
Avoid if
you have a DC motor ceiling fan. This is for AC motors only
you are not running a Z-Wave network and do not want to start one
Privacy and local-control notes
Z-Wave is fully local. No cloud, no Wi-Fi, no data collection. Fan speed control stays entirely on your local network.
Home Assistant support: supported · integration path: Z-Wave JS.
Buying reality check
Price notes: Priced similarly to the dimmer. Good value for dedicated fan control versus using a dimmer on a fan motor.
