What This Means in Practice

The specification improvements translate to meaningful real-world gains. The Thread 1.3 support is perhaps the most significant addition, enabling low-latency, mesh-networked communication with the newest generation of smart home devices from Apple, Google, Amazon, and others. If you've been investing in Thread-enabled devices — such as Eve, Nanoleaf, or newer Philips Hue products — the Hub V4 is one of the few hubs that can natively integrate them all.

The Z-Wave Plus 700 series upgrade extends range by up to 50% compared to the 500 series in the V3, and supports the newer S2 security framework with longer battery life for Z-Wave devices. The dual-band Wi-Fi means less congestion on the 2.4 GHz band, which is critical in homes with dozens of IoT devices competing for wireless bandwidth.

Performance-wise, automations that involved 5+ devices firing simultaneously executed noticeably faster on the V4. In our testing, a complex "Good Night" routine (locking doors, arming sensors, dimming lights, adjusting thermostat, and activating cameras) completed in under 2 seconds on the V4, compared to 4-5 seconds on the V3.

Thread and Matter Support: The Future-Proofing Advantage

The inclusion of Thread 1.3 and full Matter support is the headline feature of the SmartThings Hub V4, and it's worth examining in detail what this means for your smart home.

Thread 1.3: Low-Power Mesh Networking

Thread is an IPv6-based, low-power mesh networking protocol designed specifically for IoT devices. Unlike Wi-Fi, Thread devices don't connect directly to your router — instead, they form a self-healing mesh network where each device can relay messages for others. This means:

  • Extended range: Each Thread device acts as a router, extending coverage throughout your home
  • No single point of failure: If one device drops, messages automatically reroute
  • Low latency: Typical response times under 100ms for local commands
  • Low power consumption: Battery-powered Thread devices can last months or years
  • IP-native: Thread devices have their own IP addresses, making integration with other systems seamless

The Hub V4 serves as a Thread Border Router, bridging the Thread mesh network with your home's Wi-Fi/Ethernet network. This is the same role played by Apple HomePod Mini, Google Nest Hub, and Amazon Echo devices — meaning the Hub V4 can coexist and interoperate with these ecosystems through Thread.

Matter: Universal Smart Home Compatibility

Matter (formerly Project CHIP) is the industry-wide standard backed by Apple, Google, Amazon, Samsung, and over 280 other companies. It aims to solve the fragmentation problem that has plagued smart homes for years. With the Hub V4 as a Matter controller, you can:

  • Add Matter-certified devices from any brand without worrying about compatibility
  • Control devices through SmartThings, Apple Home, Google Home, or Alexa simultaneously
  • Benefit from local processing — Matter commands don't need to go through the cloud
  • Use Matter's built-in security features including device attestation and encrypted communication

As of this review, the Matter ecosystem includes over 2,000 certified products spanning lights, locks, thermostats, sensors, plugs, blinds, and more. The Hub V4 handles Matter commissioning smoothly through the SmartThings app, and we had no issues adding devices from different manufacturers to a single automation.

Setup Process: From Unboxing to Smart Home in 15 Minutes

Samsung has streamlined the Hub V4 setup experience significantly. Here's our step-by-step walkthrough of the process.

Step 1: Unboxing and Physical Setup

The retail box includes the Hub V4, a USB-C power adapter (5V/3A), a USB-C cable, a short Ethernet cable, and a quick-start guide. Plug the hub into power using the included USB-C cable and adapter. If you prefer a wired connection, connect the Ethernet cable to your router. The RGB LED will pulse white, indicating the hub is booting up and ready for configuration.

Step 2: SmartThings App Installation

Download the SmartThings app from the iOS App Store or Google Play Store. If you already have the app installed, ensure it's updated to the latest version (v1.78 or newer recommended for full V4 feature support). Sign in with your Samsung account or create a new one.

Step 3: Hub Discovery and Pairing

  1. Open the SmartThings app and tap the + icon in the top-right corner
  2. Select Add Device and then Scan QR Code
  3. Scan the QR code on the bottom of the Hub V4 (or on the included setup card)
  4. The app will discover the hub on your local network via Bluetooth Low Energy
  5. Confirm the hub's location and assign it a room name
  6. Connect the hub to your Wi-Fi network (or confirm the Ethernet connection)
  7. Wait for the firmware update check — the hub may download and install the latest firmware automatically (this took approximately 3 minutes in our test)

Step 4: Adding Your First Devices

Once the hub is online, you can begin adding devices through the app. The Hub V4 supports multiple pairing methods:

  • Zigbee: Put your Zigbee device in pairing mode and tap "Add Device" → "Scan for nearby devices"
  • Z-Wave: Use the Z-Wave inclusion process specific to your device
  • Thread/Matter: Scan the Matter QR code on your device or use the numeric setup code
  • Wi-Fi devices: Follow the manufacturer's SmartThings integration instructions
  • Bluetooth devices: Ensure Bluetooth is enabled on your phone and follow the pairing flow

Step 5: Migrating from V3 (Optional)

If you're upgrading from a V3, Samsung provides a migration tool within the app. Go to Settings → Hub Settings → Replace Hub and follow the prompts. The tool will transfer your device pairings, automations, and room assignments to the new V4 hub. In our testing, the migration of 47 devices completed in about 8 minutes, and all automations carried over without requiring manual reconfiguration. Note that some Z-Wave devices may need to be re-included due to the protocol version change from 500 to 700 series.
