Samsung has announced it will begin charging for access to its SmartThings application programming interface starting in October 2026, introducing a $5 monthly plan for non-commercial individual developers that will affect users who rely on third-party smart home tools to control their Samsung-connected devices.
The change does not impact users who control their smart home devices through the standard SmartThings application, where automatic compatibility with thousands of gadgets remains unchanged. The fee applies specifically to those using third-party platforms such as Home Assistant or custom smart home control setups that connect to Samsung devices through the SmartThings programming interface, a distinction that shifts the impact primarily onto technically minded users who have built personalised automation systems around the platform rather than casual consumers. Samsung framed the change as an investment in expanding the platform’s capabilities, stating that the additional revenue will allow it to develop enterprise-grade features that partners and users have been requesting, alongside a new Developer Center hub that will provide usage data and tools for optimising code integrations.
The reaction from the open-source smart home community has been sharp. Home Assistant founder Paulus Schoutsen described the move as a disappointment, saying that the organisation supports user choice but feels strongly that users should not have to decide whether to pay for access behind yet another cloud paywall. Home Assistant has built a significant user base precisely by offering local, privacy-first smart home control that reduces dependence on manufacturer-controlled cloud platforms, and the introduction of a monthly fee for Samsung’s programming interface adds another layer of cost and fragmentation to an ecosystem that the open-source community has consistently worked to keep accessible and manufacturer-independent.
Samsung has not specified exactly what new features or integrations will be delivered in exchange for the subscription fee, with the company offering only a general assurance that investment in enterprise-grade improvements and expanded capabilities is underway. The October start date gives current API users several months to evaluate their options, but with no concrete feature roadmap published alongside the pricing announcement, the practical value of the $5 monthly tier remains unclear for individual developers and enthusiasts weighing whether to continue building automations around the SmartThings ecosystem.
