Does Home Assistant intergrate with Smart Things?

If you’re wondering, Does Home Assistant integrate with SmartThings? the answer is a resounding yes. Home Assistant, the popular open-source home automation platform, offers seamless integration with SmartThings, Samsung’s smart home ecosystem.

This powerful combination allows you to unify your SmartThings devices—such as lights, sensors, and switches—under the Home Assistant umbrella, giving you enhanced control, local management, and automation capabilities. In this article, we’ll explore how this integration works, how to set it up, and what you need to know to make the most of it as of April 2025.

Understanding the Integration

The official SmartThings integration in Home Assistant bridges the gap between the two platforms, enabling you to manage your SmartThings devices directly within Home Assistant’s intuitive interface. Whether you’re looking to control a SmartThings bulb, monitor a sensor, or integrate these devices into complex automations, this integration makes it possible. By connecting the two systems, you can leverage Home Assistant’s local processing power and customization options while retaining access to your existing SmartThings hardware.

The integration works by mapping SmartThings device capabilities (e.g., switch, light, temperature sensor) to corresponding Home Assistant entities. Once set up, these entities can be controlled via the Home Assistant dashboard, mobile app, or voice assistants, and they can be incorporated into automations alongside devices from other ecosystems.

How to Set Up the SmartThings Integration in Home Assistant

Setting up the integration is straightforward, though it requires a few key steps. Here’s a detailed guide to get you started:

Generate a Personal Access Token (PAT)

Create a Personal Access Token, which acts as a secure key to connect Home Assistant to your SmartThings devices. Note that as of recent updates, SmartThings has shifted away from long-lived tokens toward OAuth-based or 24-hour tokens, so ensure you’re using the latest method supported by Home Assistant.

Add the Integration in Home Assistant

Open your Home Assistant web interface.
Navigate to Settings > Devices & Services > Add Integration.
Search for and select “SmartThings” from the list of available integrations.

Authorize the Connection

Follow the on-screen prompts to input your PAT.
Authenticate the connection between Home Assistant and SmartThings. This step may involve selecting the devices or hubs you want to integrate.

Device Discovery

Once authorized, Home Assistant will automatically detect and import your SmartThings devices as entities. For example, a SmartThings smart plug might appear as a switch entity, while a motion sensor becomes a binary_sensor.

After completing these steps, your SmartThings devices will be fully manageable within Home Assistant. You can now control them locally, monitor their status, or use them in automations—such as turning on lights when a SmartThings motion sensor detects movement.

Benefits of Integrating Home Assistant with SmartThings

So, why should you care about whether Home Assistant integrates with SmartThings? Here are some key advantages:

Unified Control: Manage all your smart home devices—SmartThings and beyond—from a single platform.
Local Processing: Home Assistant can control devices locally, reducing reliance on cloud services and improving response times.
Advanced Automations: Combine SmartThings devices with other Home Assistant-supported ecosystems (e.g., Philips Hue, Zigbee, or Z-Wave) for sophisticated, cross-platform automations.
Customization: Home Assistant’s flexibility lets you tailor dashboards and workflows to your exact needs, far beyond what SmartThings offers alone.

Recent Updates and Challenges

While the integration is robust, it hasn’t been without challenges. In recent years, SmartThings updated its API and PAT system, phasing out long-lived tokens in favor of OAuth authentication or shorter-lived tokens (e.g., 24-hour expiration). This caused temporary disruptions for some Home Assistant users. However, the Home Assistant community and developers responded swiftly.

As of early 2025, a revamped SmartThings integration was released, addressing these changes and improving reliability. This update ensures that the question “Does Home Assistant integrate with SmartThings?” remains a confident “yes,” even with evolving SmartThings policies.

For the latest setup instructions and troubleshooting tips, it’s wise to consult the official Home Assistant documentation or community forums. These resources provide real-time updates and user experiences that can help you navigate any quirks.

Final Thoughts

To sum up, Home Assistant does indeed integrate with SmartThings, offering a powerful way to enhance your smart home setup. The process is user-friendly, requiring only a Personal Access Token and a few minutes of configuration. Once connected, your SmartThings devices become part of Home Assistant’s expansive ecosystem, unlocking new possibilities for control and automation. Whether you’re a smart home novice or a seasoned enthusiast, this integration is a valuable tool to streamline and elevate your home automation experience.
