GE Cync and Matter: which Cync bulbs, plugs and switches work with Matter, which hub you need, and how to set them up
Direct Connect bulbs, light strips, Reveal undercabinet fixtures and wafers, and indoor/outdoor plugs with the Matter badge work over Wi-Fi. GE Lighting's August 2025 press release names the Keypad Dimmer Smart Switch and Paddle Dimmer Smart Switch as Matter-compatible; the Neutral + Traveler spec PDF, product pages, wired-switch FAQ and CSA listings also cover paddle dimmers and traveler on/off switches, even though Cync's Matter products article does not list switches. Bluetooth-only bulbs, wire-free remotes and sensors, the Cync thermostat and anything without the Matter logo do not. The Cync app path is hub-free on Direct Connect Wi-Fi products, but Matter still needs a Matter controller; the sticker QR or 11-digit code is only for the first ecosystem, and the Cync app and Matter cannot run on the same device at once.
Cync's Matter steps come from its support FAQs and GE Lighting's Cync and Matter page. The Matter products article does not list switches, so switch claims are attributed to the August 2025 press release, the spec PDF, product pages, the wired-switch FAQ and CSA listings. Follow the app and your platform's own instructions where they differ.
Which Cync devices work with Matter
The rule Cync gives is simple: look for the Matter badge on the front of the package and on the device itself. Cync's Matter FAQs say existing products without the Matter logo cannot be commissioned into a Matter system. The badge is the reliable signal, not the product family name alone.
Cync's Matter products article lists these Matter-badge products: Direct Connect Full Color bulbs in A19, A21, B11, BR30, G25, Outdoor PAR38 and ST19 shapes; Direct Connect Light Strips in 16 ft and 32 ft thin styles; Smart Reveal Undercabinet Puck and Bar fixtures in 12, 18 and 24 inch lengths; Reveal Full Color wafers in 2, 4 and 6 inch versions; the Indoor Smart Plug CPLGSTDBLW1; and the Outdoor Smart Plug CPLGOD2BLMS. GE Lighting's Cync and Matter page adds Reveal Smart Bulbs, Reveal Downlights, Reveal Undercabinet Fixtures and Reveal Puck Lights to the same Matter-badge approach.
Switches are a separate story. Cync's Matter products article does not list any switches, but GE Lighting's August 2025 press release names the Cync Keypad Dimmer Smart Switch and Paddle Dimmer Smart Switch as Matter-compatible. The Neutral + Traveler spec PDF lists "Cync, Savant, and Matter" under App Compatibility for both paddle and keypad dimmers, and the wired-switches page says the redesigned paddle dimmer is "Compatible with Cync App and Matter." The paddle on/off product page says it connects to Apple Home and Samsung SmartThings through Matter with no hub required, and the wired-switch FAQ discusses commissioning Traveler + Neutral Wire switches using Matter. CSA listings also cover Keypad Dimmer, Paddle Dimmer, On/Off Switch w Traveler and Motion Dimmer w Traveler.
What does not work with Matter: Cync's Matter FAQs say existing products without the Matter logo do not get Matter. That includes Bluetooth-only bulbs, which GE Lighting's full-color bulbs page describes as needing a Cync Smart Plug, Smart Switch or Google Home/Nest device for out-of-home control. Wire-free switches, remotes and motion sensors are Bluetooth-only and do not work with Alexa, Google or HomeKit per Cync's Wire-Free Devices FAQ. The Cync thermostat FAQ names Google Home and Alexa as voice assistants but does not mention Matter, and the thermostat is not in the Matter products article. Cameras are not in the Matter products article either. CSA listings show the A19 Direct Connect bulb certified 12/21/2022 as Matter 1.0 over Wi-Fi and Bluetooth, the indoor plug certified 09/19/2025 as Matter 1.3, the keypad dimmer certified 09/19/2024, the paddle dimmer 09/17/2024, and the on/off switch 01/16/2025, all with Wi-Fi plus Bluetooth transport. MatterCheck tracks three Cync products out of 391 tracked products, all Wi-Fi: Direct Connect Smart Bulbs, the Keypad Dimmer Smart Switch and the On/Off Switch w Traveler family. See also our products page or how to check CSA certification before assuming a model is Matter.
Wi-Fi, hubs and whether you need a Thread border router
Cync Matter devices use Matter over Wi-Fi, not Thread. Cync's Matter FAQs say Matter uses existing technologies including Wi-Fi, and the CSA listings for the A19 bulb, indoor and outdoor plugs, keypad and paddle dimmers, and on/off switches all show "Transport Interface Wi-Fi, Bluetooth." Product pages say the Wi-Fi connection is 2.4 GHz. Bluetooth is used during commissioning, not for ongoing Matter control, so you do not need a Thread border router for these Cync devices. See Thread vs Wi-Fi for the difference.
The Cync app path is hub-free on Direct Connect Wi-Fi products: the A19 product page says "no additional hardware needed," and the paddle dimmer store page says "no hub needed." That is about the Cync app and Cync's own Wi-Fi connection. Matter is different. Cync's Matter FAQs answer "Do I need a hub to set up Matter?" with "Yes, unlike the Cync app, control through Matter requires a local controller to send messages." GE Lighting's press release saying the switches integrate "without a hub" means no Cync bridge or extra Cync hardware, not that you can skip the platform's Matter controller.
What counts as a controller depends on the platform. Google's Matter page says you need a Matter-enabled hub device. Amazon's Matter page says to install the device within 30 ft (9 m) of a compatible Alexa hub. SmartThings describes the phone as the commissioner and a SmartThings hub as the controller. Apple's May 2026 support page says an iPhone on iOS 18 or later can add and control Matter accessories without a home hub, though Apple still recommends one. See hubs and Thread border routers for the full platform rules.
How to add a Cync device to Google Home, Apple Home, Alexa, SmartThings and Home Assistant
The Matter path is: install and power on the device, open your chosen app, then scan the Matter QR code or enter the 11-digit code on the device sticker. If the device is already set up in the Cync app, it cannot be directly connected through Matter; reset the device and follow the Matter setup steps. The sticker code is only for the first ecosystem; later ecosystems need a new setup code from the device settings menu in the first ecosystem. See how to add a Matter device and what to do with a lost setup code.
On the device
- Install your device and power it on.
- Open the smart home app of your choice.
- Scan the Matter QR code or enter the 11-digit code on the device sticker to complete setup.
Those three steps come from GE Lighting's Cync and Matter page. If the device was previously in the Cync app, reset it first using the model-specific reset steps in the troubleshooting section below.
Google Home
Google's Matter page says you need a Matter-enabled Google hub on your home Wi-Fi network and IPv6 enabled before adding Matter devices. In the Google Home app, add the device and scan the Matter QR code or enter the 11-digit code on the device sticker. Google also has a separate Cync setup article for the non-Matter Cync-app path, which is not Matter pairing. See Google Home Matter support.
Apple Home
Apple's Matter page says the Home app supports Matter lights, outlets and switches. Open the Home app, tap Add Accessory, and scan the Matter QR code or hold your iPhone near the accessory. If the device was previously paired in another app, tap More options and select it. An iPhone on iOS 18 or later can add Matter accessories without a home hub, but Apple recommends a home hub for remote access and automations. See Apple Home Matter support.
Alexa
Amazon's Matter page says to open the Alexa app, go to Devices, tap the plus, choose Add Device, select the Matter icon, confirm you have a Matter device, then scan the QR code or enter the pairing code. Amazon recommends installing the device within 30 ft (9 m) of a compatible Alexa hub. See Alexa Matter support.
SmartThings
SmartThings' Matter page describes the phone as the Matter commissioner and a SmartThings hub as the controller. In the SmartThings app, select Add (+), choose Add Device, scan the QR code or enter the setup code, then pick the hub and room. SmartThings says the Matter badge on the packaging indicates whether a Thread border router is needed; Cync's Wi-Fi devices do not need one. See SmartThings Matter support.
Home Assistant
Home Assistant's Matter docs say to install the Matter integration, then use the Home Assistant Companion app on Android or iPhone with Bluetooth enabled. In the Companion app, go to Settings > Connectivity > Matter, select Add device, choose "No. It's new," and scan the Matter QR code or enter the commission code manually. Home Assistant notes that Wi-Fi Matter devices often use 2.4 GHz, so keep the phone on the same 2.4 GHz network during commissioning. See Home Assistant Matter support.
What Matter can do versus the Cync app
Cync's Matter FAQs say the features available through Matter are currently on/off, brightness, white tuning and full color control, and that most Matter systems support routines and scheduling. That covers the core lighting and plug controls on Google Home, Apple Home, Alexa, SmartThings and Home Assistant. Cync's wired-switch FAQ adds a limitation: in Matter, the top two keypad buttons only support dim up/down and on/off functions, while scene control of those two buttons is supported for HomeKit users.
The Cync app keeps the Cync-specific features that Matter does not expose. Cync scenes, grouping with other Cync devices, Light Shows and Music Sync for Dynamic Effects products, firmware updates, and the cloud-based Alexa and Google voice link through Cync Voice settings all live in the Cync app, which Cync's bulb-setup article describes for commissioning into the Cync app. Cync's Matter FAQs say devices set up in the Cync app cannot be directly connected through Matter, so you choose one path per device. See Matter light bulb support, Matter light switch support and Matter smart plug support for what each device type can do per platform.
Using the Cync app and several Matter apps together
Cync's Matter FAQs are direct: devices set up in the Cync app cannot be directly connected through Matter. GE Lighting's Cync and Matter page says the same thing from the other direction — if you set up through Matter and later want the Cync app, reset the Cync device and follow the Cync app setup instructions. There is no simultaneous Cync app plus Matter mode on one device today. The cloud-based Google Home or Alexa link in the Cync app's Voice settings is a separate, non-Matter connection.
What you can do is share one Matter device across several Matter ecosystems. Cync's Matter FAQs say Cync products support 5 simultaneous ecosystems, and the setup code that comes with the device is only for the first ecosystem. To add a second, third, fourth or fifth ecosystem, get a new setup code from the device settings menu in the first ecosystem, then use that code in the next app. Home Assistant's Matter docs describe the same Multi Fabric feature, with the standard requiring at least 5 fabrics per device. See Matter multi-admin and sharing.
What MatterCheck's data says for Cync's device types
| Matter device type | Apple Home | Google Home | Alexa | SmartThings | Home Assistant | Homey | Hubitat |
|---|---|---|---|---|---|---|---|
| Matter on/off light | Yes / Yes (High) | Yes / Yes (High) | Yes / Unknown (Med) | Yes / Yes (High) | Yes / Yes (High) | Yes / Yes (Med) | Unknown / Unknown (Med) |
| Matter dimmable / colour light | Yes / Yes (High) | Yes / Yes (High) | Yes / Partial (Med) | Yes / Yes (High) | Yes / Yes (High) | Yes / Yes (Med) | Unknown / Unknown (Med) |
| Matter plug / outlet | Yes / Yes (High) | Yes / Yes (High) | Yes / Unknown (Med) | Yes / Yes (High) | Yes / Yes (High) | Yes / Yes (Med) | Yes / Yes (Med) |
| Matter fan / air purifier | Yes / Unknown (Med) | Yes / Yes (High) | Yes / Unknown (Med) | Yes / Yes (Med) | Yes / Yes (High) | Yes / Yes (Med) | Unknown / Unknown (Med) |
Each entry: pairs / usable as an automation trigger (confidence), per Matter device type in MatterCheck's data — not a test of Cync products. Cync in-wall switches certify as on/off or dimmable lights, not as generic buttons.
MatterCheck checks 27 Matter device types on 7 platforms and tracks 3 Cync products (Direct Connect Smart Bulbs (Matter generation), Wi-Fi; Keypad Dimmer Smart Switch, Neutral + Traveler Wire (CSWDMBLK5T1/MSWF), Wi-Fi; On/Off Switch w Traveler (Paddle CSWONBLPT2/MSWF, Toggle CSWONBLTT2/MSWF, Button CSWONBLBT2/MSWF), Wi-Fi). These results are per Matter device type, not tests of Cync products, and the confidence label shows how sure MatterCheck is about each result. Cync in-wall switches certify as on/off lights or dimmable lights, Direct Connect bulbs as colour lights, and plugs as plug-in units. Pairing is Yes on Apple Home, Google Home, Alexa, SmartThings, Home Assistant and Homey for those types; Hubitat is Yes for plugs and Unknown for on/off lights, dimmable lights and fans. Alexa automation triggers are Unknown for on/off lights and plugs, and Partial for dimmable lights. See the on/off light, dimmable / colour light, plug / outlet and platform comparison pages for the sources.
When a Cync device won't pair or stops responding
- Make sure your phone and the Cync device are on the 2.4 GHz Wi-Fi band. Cync's plug setup article says Cync is not compatible with 5 GHz networks, and the product pages specify 2.4 GHz Wi-Fi.
- Enable IPv6 on your home network. Google's Matter page says setup can appear to succeed without IPv6 but control eventually fails.
- Check for the Matter badge on the device and package. Cync's Matter FAQs say products without the Matter logo cannot be commissioned into Matter.
- If the device is already in the Cync app, factory reset it before trying Matter. Cync app and Matter cannot run on the same device at once.
- Use the sticker QR or 11-digit code for the first ecosystem. For additional ecosystems, get a new code from the first ecosystem's device settings, not the sticker.
- Keep the phone close to the device during commissioning. Home Assistant's Matter docs say Bluetooth is used for pairing, and the phone sends network credentials over Bluetooth.
- Make sure the platform's Matter controller or hub is online and on the same network. Cync's Matter FAQs say Matter requires a local controller.
- For bulbs, use a simple on/off switch or power strip for reset timing. Cync's bulb-reset article says three-way dimming lamps, rotary dimmers or multi-function switches will not work.
- For plugs, hold the side or outlet button at least 10 seconds until the LED turns red. For dimmer switches, hold on/off 10 seconds or use the pinhole behind the faceplate for 5 seconds.
- Power cycle the device if it is not in setup mode. Cync's plug setup article says the LED should blink blue when ready.

Frequently asked questions
Does GE Cync work with Matter?
Yes, for the current Matter-badge generation. Cync's Matter FAQs say to look for the Matter badge on the package and on the device itself. GE Lighting's Cync and Matter page says new generation Cync products are compatible and can connect directly to Apple Home, Samsung SmartThings, Google Home and Amazon Alexa.
Which Cync devices support Matter?
Cync's Matter products article lists Direct Connect Full Color bulbs, Direct Connect Light Strips, Smart Reveal Undercabinet fixtures, Reveal Full Color wafers, and the Indoor and Outdoor Smart Plugs. GE Lighting's August 2025 press release and the Neutral + Traveler spec PDF add the Keypad Dimmer and Paddle Dimmer Smart Switches, and CSA listings cover traveler on/off switches and a motion dimmer. Bluetooth-only bulbs, wire-free devices, the thermostat and cameras are not in the Matter list.
Do Cync Matter devices use Thread or Wi-Fi?
They use Matter over Wi-Fi. Cync's Matter FAQs describe Wi-Fi as the connecting technology, and the CSA listings for the A19 bulb, plugs and switches all show Wi-Fi plus Bluetooth transport. Bluetooth is for commissioning, not ongoing control, so no Thread border router is needed.
Do I need a hub for a Cync Matter device?
For the Cync app, no — Direct Connect products connect to 2.4 GHz Wi-Fi with no additional hardware. For Matter, yes: Cync's Matter FAQs say control through Matter requires a local controller. What that controller is depends on your platform, such as a Google Nest hub, a compatible Echo, a SmartThings hub, or an Apple home hub (Apple's Matter page says iOS 18 or later can add Matter accessories without a home hub).
Can I use the Cync app and Matter at the same time?
No. Cync's Matter FAQs say devices set up in the Cync app cannot be directly connected through Matter. To switch from Matter to the Cync app, reset the device and follow the Cync app setup instructions. The cloud-based Alexa or Google link in the Cync app is a separate path, not Matter.
Where is the Cync Matter pairing code?
On the device sticker. GE Lighting's Cync and Matter page says to scan the Matter QR code or enter the 11-digit code on the device sticker. That code is only for the first ecosystem; for additional ecosystems, get a new setup code from the device settings menu in the first ecosystem.
Does the Cync thermostat work with Matter?
No. The Cync thermostat FAQ names Google Home and Alexa as compatible voice assistants but does not mention Matter, and the thermostat is not in Cync's Matter products article. The thermostat uses the Cync app and cloud voice links instead.
Does Cync work with Apple Home through Matter?
Yes, for Matter-badge devices. GE Lighting's Cync and Matter page lists Apple Home as a supported app, and the store pages for the paddle dimmer and toggle switch say they connect to Apple Home through Matter. This is separate from the older C-Reach HomeKit path for Bluetooth lights, which Cync's HomeKit article describes and which is no longer manufactured or sold.
