Samsung will begin charging for access to its SmartThings API starting in October 2026, introducing a new paid tier for individual developers at $4.99 per month. The move is aimed at funding further development of enterprise-grade features, but it could impact some advanced users and third-party integrations.
Samsung announced that from October 2026, it will implement a tiered pricing structure for its SmartThings API, including a $4.99 monthly plan specifically for non-commercial, individual developers. This change is part of Samsung’s effort to invest in enhancing its smart home platform, including stability improvements, new integrations, and a refreshed Developer Center hub, according to the company.
While the primary target appears to be developers, the policy change is likely to affect some advanced smart home users who access the API directly or via third-party tools such as Home Assistant. Paulus Schoutsen, founder of Home Assistant, confirmed that their integration will be impacted by these new ‘personal plans,’ which could restrict or require payment for certain functionalities.
Impact on Smart Home Ecosystems and Users
This change could alter how developers and advanced users interact with Samsung’s smart home platform, potentially limiting free access for some. It signals a shift toward monetizing API usage, which may influence third-party integrations and the broader smart home ecosystem. Consumers relying on custom or third-party tools might face increased costs or reduced flexibility, affecting the smart home experience for tech-savvy users.

Samsung’s Strategy and Past API Access Policies
Samsung has historically offered free access to its SmartThings API, encouraging third-party development and integrations to expand its ecosystem. The move to introduce paid tiers marks a significant change, aligning with broader industry trends of monetizing developer platforms. The company states that the revenue will fund improvements and new features, but specifics of the pricing structure and thresholds remain unclear.
This announcement follows similar moves by other tech firms to monetize developer access, reflecting a shift in platform economics. The timing coincides with Samsung’s ongoing efforts to position SmartThings as a more enterprise-oriented platform, though it remains popular among individual users and DIY smart home enthusiasts.
“The introduction of paid tiers could restrict access for some hobbyists and small-scale developers, potentially impacting the flexibility of third-party integrations.”
