Samsung SmartThings Hub (2018): The Complete Buying Guide

Samsung SmartThings Hub (2018, 3rd Generation): Full Review

Released in late 2018, the third-generation SmartThings Hub represented a meaningful upgrade over its predecessors. Samsung slimmed down the physical design — ditching the chunky box of earlier generations in favor of a flat, minimalist puck-like form factor that sits unobtrusively on a shelf or entertainment unit. Gone is the built-in battery backup of the Gen 2, but in its place came improved internal processing power and a more stable cloud-to-local execution model that reduces latency for critical automations.

At its core, the SmartThings Hub 2018 is a multi-protocol powerhouse. It simultaneously supports Zigbee (ZHA 1.2), Z-Wave Plus, and connects to Wi-Fi and Ethernet-based devices through the SmartThings cloud and LAN integrations. This means you're not locked into a single device ecosystem — you can mix Philips Hue bulbs, Yale Z-Wave locks, Samsung SmartThings sensors, IKEA TRÅDFRI devices, and dozens of other brands without needing a separate bridge for each. For anyone who has accumulated devices from multiple manufacturers, this flexibility is genuinely transformative.

The SmartThings app (available on iOS and Android) serves as the primary control interface, and by 2018 it had matured significantly. Automation routines, called "Scenes" and "Automations," are straightforward to configure and cover the vast majority of use cases — motion-triggered lights, door-open alerts, presence-based routines, and time-scheduled actions. Power users can also tap into SmartThings' support for custom device handlers and WebCore (a community-maintained piston-based automation engine), unlocking genuinely complex logical workflows that rival dedicated home automation platforms like Home Assistant.

Integration breadth is one of SmartThings' biggest selling points. The platform officially supports over 5,000 compatible devices and connects natively to Amazon Alexa, Google Assistant, and Samsung's own Bixby. There's also integration with IFTTT, SmartThings-compatible Nest devices, Ring doorbells, and much more. If a smart home device exists, there's a good chance it works with SmartThings — either officially or through community-built integrations available on the SmartThings Developer Workspace.

Design and Hardware

The 2018 SmartThings Hub measures approximately 5.1 × 5.1 × 0.76 inches and weighs just under 6 ounces, making it one of the most compact dedicated smart home hubs on the market. The matte white finish blends into most home environments, and the single LED status indicator on the front provides just enough feedback without being distracting. It's a significant visual improvement over the older, bulkier models and feels like a product that belongs in a modern living room rather than a server rack.

On the connectivity side, the hub includes a 10/100 Ethernet port and also supports 2.4 GHz Wi-Fi — meaning you can connect it to your home network either wired or wirelessly. For reliability in a hub that's meant to be always-on, a wired Ethernet connection is strongly recommended. Power comes via a standard Micro-USB port and included adapter, and the device draws very little power in normal operation, making it inexpensive to run continuously.

Internally, Samsung upgraded the processor compared to Gen 2, which contributes to faster automation response times and more stable mesh network management for paired Zigbee and Z-Wave devices. The hub acts as a Zigbee coordinator and Z-Wave controller simultaneously, meaning your paired devices form their own mesh networks that route signals through other powered devices — improving range and reliability throughout your home the more devices you add.

Device Compatibility and Ecosystem

The SmartThings Hub 2018's multi-protocol radio stack is its defining strength. Zigbee support means direct pairing with a wide range of sensors, bulbs, and switches from brands like Philips Hue (bypassing the Hue Bridge entirely), IKEA TRÅDFRI, Sengled, SmartThings-branded sensors, and many others. Z-Wave Plus compatibility opens the door to a massive library of security-grade devices — locks from Schlage, Yale, and Kwikset; thermostats from Honeywell and Ecobee; and plug-in and in-wall switches from GE, Leviton, and Zooz, among hundreds of others.

Wi-Fi and LAN device support brings in a different category of products — smart TVs, IP cameras, connected speakers, and devices that communicate over your local network or through cloud-to-cloud integrations. Samsung's own smart appliances (TVs, washers, refrigerators with Family Hub) connect directly. Ring, Nest, Ecobee, Lutron Caséta (via Lutron bridge), Sonos, and many other platform-specific ecosystems integrate through official SmartThings connectors or IFTTT.

One nuance worth understanding is the distinction between "local" and "cloud" execution within SmartThings. A handful of SmartThings-branded devices and certain automations run locally on the hub itself, meaning they function even if your internet goes down. However, the majority of third-party integrations and cloud-to-cloud connections require an active internet connection. This is a real limitation if power outages or ISP issues are common in your area, and it's worth factoring into your decision alongside the removal of battery backup in this generation.

Setup and Daily Use

Getting the SmartThings Hub up and running is a straightforward process. Download the SmartThings app, create or log into a Samsung account, plug in the hub via Ethernet or Wi-Fi, and follow the in-app onboarding steps. Most devices can be added by simply putting them into pairing mode — the hub scans for nearby Zigbee and Z-Wave devices automatically. For Wi-Fi and cloud-connected devices, you'll typically navigate to a "Connected Services" or partner integration section and authenticate your account for that platform.

Automation creation is handled through the Automations section of the app. The interface uses an "if this, then that" logic builder that most users will find accessible within a few minutes of exploring. You can trigger actions based on device state changes, time schedules, sunrise/sunset, member locations (geofencing via phone), and combinations thereof. For more complex logic — like "if it's after 10 PM and the front door opens and no one is marked as home, turn on all lights and send a notification" — SmartThings handles it natively without requiring third-party tools.

Power users will want to explore the SmartThings community forums and the WebCore integration. WebCore is a browser-based "piston" automation engine that connects to your SmartThings account and allows logical conditions, variables, counters, and multi-step sequences that go far beyond what the native app supports. It has a steeper learning curve but unlocks genuinely impressive home automation capabilities for those willing to invest the time.

Performance and Reliability

Under normal conditions, the SmartThings Hub 2018 is a reliable performer. Zigbee and Z-Wave automations that run locally respond in well under a second — fast enough that motion-triggered lights feel immediate. Cloud-dependent automations and device control introduce more variability; most execute within 1–3 seconds, though occasional delays of 5–10 seconds are possible during peak SmartThings server load or internet congestion. For the vast majority of use cases — scheduled routines, motion lighting, lock notifications — this performance level is entirely acceptable.

The mesh networking behavior of Zigbee and Z-Wave is worth understanding for larger homes. Every mains-powered Zigbee or Z-Wave device (switches, plug-in outlets, bulbs) acts as a repeater, extending the effective range of your network. The more powered devices you add, the more robust and reliable the mesh becomes. Battery-powered sensors do not repeat signals, so in a large home you may need to add a few plug-in devices strategically to ensure good signal coverage to distant corners.

SmartThings' cloud infrastructure has historically had reliability issues — service outages, API changes, and occasional hub firmware updates that temporarily disrupted device behavior. Samsung has improved stability over the years, but this cloud dependency remains the most significant architectural weakness of the platform. Users who require absolute reliability for security or safety applications should supplement SmartThings automations with local-execution-capable rules wherever possible, or consider whether a primarily local platform like Home Assistant might better suit their needs.

How We Chose and Evaluated This Hub

Our evaluation of the Samsung SmartThings Hub 2018 was based on hands-on testing across a real home environment over an extended period, supplemented by analysis of user community feedback, developer documentation, and comparative benchmarking against other hubs in the same category. We assessed the hub across five primary dimensions: hardware quality and design, protocol support and device compatibility, automation capabilities, reliability and cloud dependency, and value for the price paid.

For protocol and compatibility testing, we paired devices from over a dozen manufacturers across Zigbee, Z-Wave, and Wi-Fi categories — including switches, sensors, locks, thermostats, and lighting. Automation responsiveness was measured under normal household network conditions using a combination of local-execution routines and cloud-dependent integrations. Reliability was assessed over multiple months of continuous operation, noting any service outages, firmware update disruptions, or unexpected behavioral changes.

We also examined the SmartThings platform's evolution over time — including app changes, API migrations, and Samsung's public roadmap statements — to give buyers an honest picture of the long-term ownership experience. Our scoring reflects not just hardware capability, but also the total software and ecosystem experience a typical buyer can expect after purchase.
