Samsung has confirmed it will begin charging some developers to access its SmartThings API from October, marking a significant change for users who rely on the platform beyond the standard SmartThings app.

While everyday SmartThings customers who use Samsung’s app to control compatible smart home products will not be affected, the new pricing introduces a subscription for individuals using the API through third-party software and custom automation platforms.

Under the revised pricing model, non-commercial individual developers will be required to pay A$7.70 per month to continue using the SmartThings API. The new fee primarily affects enthusiasts who integrate Samsung-connected devices into alternative smart home ecosystems such as Home Assistant or who have built their own custom automation solutions.

The move has drawn criticism from the open-source smart home community, which has long embraced free access to the SmartThings API. Home Assistant founder Paulus Schoutsen said the decision forces users to choose whether they are willing to pay another cloud-based subscription simply to maintain existing functionality.

Samsung says the additional revenue will help fund new enterprise-grade capabilities, broader integrations and future platform improvements. However, the company has not yet detailed the specific features subscribers will receive in return.

One confirmed addition is a redesigned Developer Center, which will provide developers with improved usage statistics and diagnostic tools to help optimise applications built on the SmartThings platform.

The changes are scheduled to take effect in October. Until then, access to the SmartThings API will remain available at no cost.
