Samsung released an upgraded toolkit for developers building apps on SmartThings, launching a new Developer Center and rewritten documentation on June 23, 2026, according to a SmartThings community announcement.

The update is aimed squarely at the thousands of developers writing software for the SmartThings platform — a group that has grown as Samsung has pushed the ecosystem beyond just smart home gadgets into commercial territory like apartment buildings and office complexes. The new Developer Center puts API references, tools, and getting-started materials all in one place, rather than scattered across different pages. When a company rebuilds documentation like this, it usually means the underlying API has changed, or the company is serious about making it easier and faster for newcomers to build on the platform.

What SmartThings Is Trying to Build

SmartThings has been deliberately expanding beyond a single vendor's walled garden. The SmartThings Enterprise API for Multifamily, released earlier, lets developers build property management software for apartment complexes and rental properties — intentionally designed to be cheaper and quicker to develop for. That signals Samsung wants independent developers and third-party companies to build on the platform, not just Samsung itself.

The tooling refresh fits into that same push. But you can see the real ambition in what Samsung announced at CES 2024: a partnership with Tesla to connect SmartThings Energy with Tesla's charging and power systems. That January 2024 announcement made SmartThings the first platform to officially hook into Tesla's API for home energy — meaning a single app can now coordinate your home battery, solar panels, and electric car charging in one interface. That kind of integration only works if the underlying developer platform is solid enough to handle it.

The Bigger Picture

The smart home market has spent nearly two decades fragmented. Devices from different makers often don't talk to each other cleanly, which has frustrated both builders and everyday users. The Matter protocol — a new open standard — was supposed to solve this by making all smart devices speak a common language. It helps, but it only fixes one layer of the problem: getting devices to connect.

What Matter doesn't handle is the layer above that — what developers call the application layer. That's where the logic lives: orchestrating when your solar panels charge your battery versus charging your car, managing access to apartment buildings, or automating routines that work across many different devices from different brands. SmartThings is positioning itself as the platform that makes this layer work smoothly. Good API documentation and tools directly determine whether developers choose to build here or look elsewhere.

What Remains Unclear

A developer tooling refresh, by itself, is not headline news. It gains weight when you see the full picture: an enterprise API for multifamily developers, a live integration with Tesla's residential energy products, and now a stated commitment to reducing friction. But Samsung has not published a detailed list of what actually changed in the API itself — only that the documentation is better. That's an important distinction. Improving the front door to existing features is different from adding new capabilities and explaining them well. Developers evaluating the platform will want to know which one this is before they commit time to integration work.

The real test will come quickly: developers will try the new tooling themselves, and their feedback will surface in community forums faster than any press release. Documentation that promises more than it delivers tends to reveal itself within weeks.
