Choose Samsung SmartThings if you already rely on supported Zigbee or Z-Wave devices, want a hub-centered setup, or use Samsung appliances and services. Choose Google Home if your home is built around Google or Nest controls and your devices already work with Google Home. For Matter devices, check the exact hub, device features, and whether Thread is required: Matter improves interoperability, but it does not make every feature work identically in both platforms.
This is a criteria-based comparison, not a hands-on test. The right choice depends on your installed devices, the routines you want, the radios in your devices, and whether you are willing to add a hub.
Should you use SmartThings or Google Home?
Start with the devices and routines you already have, not the platform’s headline compatibility count. A device may pair successfully yet expose only some of its controls, sensor states, or automation capabilities.
- Lean toward SmartThings if your home has supported Zigbee or Z-Wave products, needs a compatible hub, or uses Samsung appliances and services.
- Lean toward Google Home if you primarily want Google or Nest controls and your existing devices are listed as compatible with Google Home.
- For a Matter-based setup, verify the exact controller, device category, and feature support in each platform. Check Thread separately from Matter.
Google says its Works with Google Home ecosystem includes over 80,000 compatible devices in its current compatibility documentation accessed in 2026. That is a branded-compatible-device count, not a count directly comparable with Matter device types. A Connectivity Standards Alliance-hosted Samsung SmartThings report in 2025 said SmartThings supported 50 Matter device types through Matter 1.4. The scopes and dates differ, so neither figure establishes which platform will support a particular device or feature.
How do SmartThings and Google Home differ?
| Decision | SmartThings | Google Home | What to verify |
|---|---|---|---|
| Existing devices | Hubs support Zigbee, Z-Wave, and LAN-connected devices; support depends on hub model and firmware. | Supports Works with Google Home devices and Matter through compatible hubs. | Search each model in the platform’s compatibility information and confirm the functions it exposes. |
| Matter setup and control | Requires a supported Matter controller and commissioner; Matter multi-admin can share an onboarded device with another service. | Requires a Matter hub for setup, local Matter control, and remote access. Google says IPv6 must be enabled on the home network for Matter to work properly. | Check the hub, router, IPv6 configuration, and device protocol before buying. |
| Thread | Requirements vary by controller. SmartThings says the 2015 hub needs a third-party Thread border router for Thread connections. | Some Google Home hubs include Thread border-router support; others do not. | Match the hub’s radios to the device. A Matter hub is not automatically a Thread border router. |
| Automations | Routines use IF conditions and THEN actions, with documented time/day, device-activity, and manual triggers. Edge supports local execution for supported hub-connected commands and automations. | Supports Matter device controls through app controls, voice commands, and automations; available device types and capabilities vary. | Confirm that the needed sensor state or device feature is available as a trigger or action. Do not assume every routine runs locally. |
Will your existing devices work?
Check every important device by exact model number before switching or buying a hub. Compatibility at the brand or protocol level does not guarantee that every feature appears in the app. For example, the feature you need for a routine may not be exposed even when basic control works.
SmartThings is worth evaluating when your installed equipment includes supported Zigbee or Z-Wave devices. Google Home’s Works with Google Home ecosystem may suit households with devices already configured for that platform. In either case, consult current compatibility information for the specific model and verify the functions you rely on.
A switch can also involve re-pairing devices and rebuilding routines. SmartThings warns that factory-removing a hub deletes its associated connections, routines, configurations, and services. Before removing or resetting a hub, document what is paired and how each routine is configured.
What Matter does—and does not—solve
Matter is intended to improve compatibility across smart home platforms, but it does not remove hub requirements or guarantee feature parity. Google describes Matter as “the industry standard for smart homes designed to eliminate compatibility issues” in its Matter preparation guide. That is Google’s description of the standard, not a guarantee that every advanced device function works the same in every app.

SmartThings requires a supported controller and commissioner. SmartThings also supports Matter multi-admin: after a device is onboarded, it can be shared with another service while remaining connected to SmartThings. SmartThings says, “Most Matter devices work with SmartThings right out of the box, making it easier than ever to build a connected home,” on its Matter integration page; this is platform-owner language, not an independent comparison.

Before choosing a Matter product, check the exact device category and the capabilities each platform supports. A Matter badge is evidence of standard support, not proof that a feature you need—such as a particular sensor reading or lock control—is exposed in both apps.
Do you need a hub, and does Thread matter?
For Matter, plan around the hub requirements of the platform you choose. On Google Home, the hub handles Matter setup and local and remote control. Google distinguishes hubs that support Wi-Fi Matter devices from those that also work as Thread border routers. Its Matter guide also says IPv6 must be enabled on the home network for Matter to work properly.
Thread is a separate consideration because a Thread Matter device needs a compatible Thread border router. SmartThings says its 2015 hub requires a third-party Thread border router for Thread connections. On Google Home, consult the current compatible-device list to see which specific hubs include Thread support. Do not infer Thread support from the words “Matter hub” alone.

The relevant comparison is the hardware and protocols already in your home, not a generic claim that one platform supports more.
Compare the automation you want to build
Write down the trigger and action for each important routine—for example, a sensor changing state as the trigger and a light changing as the action. Then check whether the platform exposes both parts for the exact devices involved.

SmartThings documents routines as IF conditions and THEN actions, with triggers including time or day, device activity, and manual operation. Its Edge architecture can run supported hub-connected commands and automations locally, but this is not a guarantee that every integration or routine runs locally. Google Home supports Matter device control through automations and voice commands, though the device types and capabilities available to an automation can vary.
Neither an automation editor nor protocol compatibility alone establishes whether your particular routine will work. Confirm the required trigger, action, and execution behavior for the devices you plan to use.

How to make the choice for your home
- Inventory the installed devices. Record each exact model, connection type where known, and the controls or sensor readings you actually use.
- Check compatibility and capabilities. Look up each model in the relevant current platform information; verify specific functions, not just the ability to pair.
- List your essential routines. For each one, identify its trigger and action, then confirm both are available in the platform.
- Check hub and network requirements. Confirm Zigbee, Z-Wave, Matter, or Thread support as applicable, plus IPv6 for Google Matter operation.
- Plan any migration. Account for re-pairing and rebuilding routines. If you use a SmartThings hub, do not factory-remove it without recording its associated connections and configurations.
Which platform should you choose?
SmartThings is the stronger fit to investigate when supported Zigbee or Z-Wave devices, a hub-centered setup, or Samsung household products are central to your system. Google Home is the more natural fit when your controls and existing devices are centered on Google or Nest. If Matter is central, decide by the exact hub, Thread support, network configuration, device category, and required features—not by the Matter label alone.
There is no platform-neutral ranking established here for speed, reliability, safety, or ease of use. The practical winner is the one that supports your installed devices and required routines with the least disruptive setup.
