The smart home hub market has two extremes. Samsung SmartThings Station: plug it in, scan a QR code, and your smart home works in 10 minutes. Home Assistant Green: spend a weekend configuring automations that will run flawlessly for the next five years. Both are valid. The right choice depends on how much control you actually want.
Setup: 10 Minutes vs One Weekend
The SmartThings Station (80 pounds) is a white square. Plug it into power. Open the SmartThings app. It discovers Zigbee, Thread, and Matter devices automatically. The entire setup — hub, three sensors, two bulbs — takes under 15 minutes. You will never open a terminal or edit a YAML file.
The Home Assistant Green (130 pounds) requires connecting to your network, navigating to homeassistant.local, and following a guided setup that ends with a dashboard showing zero devices. You then add integrations one by one: Zigbee via ZHA or Zigbee2MQTT, Wi-Fi devices via their respective APIs, Z-Wave via a USB dongle. It takes an afternoon. It works forever afterward.
Device Compatibility: 1,000+ Integrations vs Everything
SmartThings supports approximately 300 device types across major brands. It covers the mainstream: Philips Hue, Ring, Nest, Aqara, Yale. If your devices are from brands you have heard of, SmartThings works.
Home Assistant supports over 2,500 integrations — effectively every smart device ever manufactured, including obscure Chinese Zigbee sensors, DIY ESP32 boards, and legacy X10 equipment from the 1990s. If a device has ever connected to anything, Home Assistant can talk to it.
Who Should NOT Buy Home Assistant
If you want a smart home that just works and you never want to think about it, buy SmartThings. Home Assistant is a hobby as much as a product. Firmware updates can break integrations. Community add-ons sometimes get abandoned. You will spend time maintaining it — not much, but not zero. If the idea of debugging a Zigbee network at 11pm sounds like a nightmare, Home Assistant is not for you.
Verdict
Buy Home Assistant Green (130 pounds) if you want maximum device compatibility and total control. The initial time investment pays off in capability. Buy SmartThings Station (80 pounds) if you want a smart home that works out of the box with zero maintenance.
