Leviton Decora Smart Wi-Fi Fan Speed Controller, 2nd Gen (D24SF-1BW)

Compiled by SmartHomeWorkflow Research · Leviton · Switches & Dimmers · ~$42.99 (at time of research (Leviton's own store) — never treated as a live price)

Exactly which product this is^[2]

Model number: D24SF-1BW
Generation: Not established
Region this page covers: Not established
Also sold or listed as: Not established

“Not established” means we have not sourced that detail yet — not that the product has no model number, generation or regional variant. We publish the gap rather than filling it.

Compatibility

Ecosystem	Support	The catch
Amazon Alexa	WorksWorks with this ecosystem^[3]	Listed in Leviton's spec sheet works-with row.
Google Home	WorksWorks with this ecosystem^[3]	Listed as 'Hey Google' in Leviton's spec sheet.
Apple Home	WorksWorks with this ecosystem^[3]	HomeKit is listed on the spec sheet, but taking Leviton's Matter firmware update REMOVES the existing HomeKit connection and forces re-pairing via a Matter code. Choosing Matter and keeping HomeKit are not both available.
SmartThings	WorksWorks with this ecosystem^[3]	Listed in Leviton's spec sheet works-with row.
Home Assistant	Doesn't workVerified: does not work with this ecosystem^[4]	Home Assistant's Leviton integration page documents Z-Wave models only (DZ6HD, DZ15S, ZW4SF, DZPD3, DZPA1, ZW15R). No official core integration covers the Decora Smart Wi-Fi line, and Leviton does not list Home Assistant.

Protocols: WIFI · BLUETOOTH^[1][3]

Needs before it works: No hub or bridge. The spec sheet states it connects directly to 2.4 GHz Wi-Fi. Schedules and settings are stored on the device and continue to run during an internet outage; app and voice control go through the My Leviton cloud.^[3]

What it can do^[9]

You can tell it to

On/off
Fan mode

It reports

Not established — we could not confirm this from vendor documentation

Whether each platform's automations and routines can use it — not just whether its app shows it.

What it does	Apple Home	Google Home	Alexa	SmartThings
On/off	✓ routines can use it	✓ routines can use it	? not stated	✓ routines can use it
Fan mode	✓ routines can use it	✓ routines can use it	? not stated	✓ routines can use it

Platform documentation: Amazon Alexa — automation engine ceiling (eight terms observed; residue inconclusive by refusal) (2026-09-01), Apple Home — automation engine ceiling (2026-09-01), Google Home — automation engine ceiling (2026-09-01), SmartThings — automation engine ceiling (2026-09-01)

Alexa: Leviton names the speeds Alexa can set, which is stronger than a generic works-with badge: "Use your voice to control ceiling fan speeds (low, medium, high, and max) from compatible Alexa devices such as an Amazon Echo, Echo Show, the Alexa app, or the Decora Smart Voice Dimmer with Amazon Alexa Built-In."

Listed capabilities are what we could establish from vendor documentation. An ability missing here is unestablished — not necessarily absent.

Subscription reality^[14]

✓ Works without a subscription: Yes.

Vendor account required: Not established — we have not sourced this yet.

No subscription, tier, or paywall appears on the product page, the Leviton store listing, or the spec sheet. Established by absence across three manufacturer surfaces rather than by an affirmative statement.

Maintenance reality

Works without the internet: Partly — some of it keeps working and some of it does not. See the detail below.^[1]
Neutral wire required. Fan motor rated 1.5 A max at 120 VAC 60 Hz; split-capacitor or shaded-pole motors only. Standard wall box, 1.31 in device depth. Multi-way supported via DD00R/DD0SR wired companions or DAWDC/DAWSC wire-free Anywhere Companions (5-year battery). 2.4 GHz Wi-Fi only. Two-year limited warranty.
Security updates: No security-update support date is on record for this model yet. We haven't yet checked whether Leviton publishes one, so this is a gap in our research — not a statement about the manufacturer.

The catch

It controls the fan motor only. Leviton's spec sheet states it is not for use with lighting loads or combined ceiling fan light kits, so a fan with an integrated light needs a second device. A neutral wire is required. Leviton's own sources also disagree about Matter: the product page advertises it, while Leviton's Matter support article lists only four devices and this is not among them.

Who it's for

Households on Alexa, Google Home, Apple Home, or SmartThings who want hub-free Wi-Fi control of a ceiling fan motor and have a neutral wire. Not a fit for Home Assistant users, for fans with integrated light kits controlled from one switch, or for anyone relying on the advertised Matter support before Leviton resolves its own documentation.

Sources & method

Numbered sources below back the facts marked with the matching number above. This is a research profile: compiled from manufacturer documentation, certification registries, and published testing — we state facts, not verdicts, and we have not physically tested this unit. How we work →

Where these facts come from

No mark: Everything on this page without a mark comes from the people answerable for it: the manufacturer, the platform's own documentation, or a certification register. That is the standard we hold ourselves to.
Seller's spec sheet: This fact comes from a retailer's or a reviewer's specification listing instead of from the manufacturer. A few compatibility answers still rest on one, and we are replacing those with the maker's own word as we find it. The date is when we last checked, because these listings change without notice.
Someone's observation: This fact comes from an owner, a forum, or a community project — someone with the product in front of them rather than the company that makes it. Worth knowing, and not the same as the maker saying so.

Below is every source behind the facts on this page, numbered so you can trace any one of them. Each is quoted in the source's own words, with the date we last read it — we keep the wording exact rather than tidying it, so you can check what was actually said.

[9] Leviton's own Decora Smart Wi-Fi Fan Speed Controller (2nd Gen) product data sheet (© 2022), read in full 2026-08-20. It states the control set directly: the D24SF "makes it easier than ever to make your ceiling fan smart with quiet fan control and four speeds", with "built-in fan speed level buttons to set your fan to low, medium, high, or max speeds in addition to on/off control with the Decora rocker". App capability: "With the My Leviton app you can configure fans to turn ON/OFF and adjust speeds to circulate the air at scheduled times. Adjust minimum and maximum fan speed settings. Choose a preset fan speed when turned on or optionally have the fan always turn on at the last speed. Use the auto-shutoff feature to act as a countdown timer." Platforms: Alexa ("control ceiling fan speeds (low, medium, high, and max)"), "WORKS WITH HEY GOOGLE: Use your voice to control connected fans with Hey Google or from the Google Home app", "WORKS WITH APPLE HOMEKIT: Add to Apple Home and control with the native Apple Home app on your iOS device", plus IFTTT and a Schlage lock-activity trigger. — Read on the maker's own site, verified 2026-08-20

That is a network requirement, not an enumeration of the bands, and it does not say 5 GHz is unsupported — the same reading applied to Leviton's D26HD dimmer. The Wi-Fi band stays unanswered, recorded as checked and not published. The app's platforms likewise: the page names the My Leviton app but no platform, and Leviton's family-level statement is already cited on the D26HD record rather than duplicated here. — Read on the maker's own site, verified 2026-09-09
