Samsung’s SmartThings API fee starts next month. From October 2026, non-commercial individual developers have to pay $5 a month for API access. Samsung confirmed the plan back in June, and it is now going ahead on that timeline.
Who actually has to pay the SmartThings API fee
If you only use Samsung’s SmartThings app to control lights, plugs and appliances, nothing changes. There is no fee for that, and no change to how the app works.
The charge lands on people who reach SmartThings from somewhere else. A Home Assistant setup that pulls Samsung devices into one dashboard talks to the SmartThings API. That access has been free. From October it sits behind a monthly payment for individual developers.
Samsung said in June that SmartThings has more than 460 million registered users worldwide. Only a small slice of that base touches the API directly. For that slice, the change is blunt. An integration that already works now carries a running cost.
Samsung’s reasoning, and what it leaves out
Samsung told SamMobile the money would let it invest more in enterprise-grade features that partners and users have been asking for. That is a fair thing for a platform owner to want.
It is also worth reading plainly. The $5 does not repair anything that was broken. It buys continued access to something that already worked at no charge. The enterprise features are a promise about later, while the bill begins in October.
Smart-home setups are built on years of small dependencies, and this is a reminder that the account layer underneath them is Samsung’s to reprice. Owners have had reason to watch that layer before, as past Samsung account deactivations showed.
What else Samsung might start charging for
Korean outlet g-enews.com reports that Samsung is evaluating paid access for organizations as well as individuals. The segments named are energy companies and hospitality businesses, which use SmartThings to manage heating and cooling across many rooms.
The idea described is that outside firms would pay usage fees to serve their own customers through SmartThings. No tier and no figure have been attached to it. As of September 27, no pricing for such a tier has surfaced, and Samsung has not presented it as a decided plan.
For now, the individual developer fee is the only firm number on the table. If you run a third-party integration against SmartThings, October is the month it starts costing you money.
