Samsung will charge four point ninety nine dollars for the SmartThings API starting in October

Published on June 28, 2026 | Translated from Spanish

Since October, Samsung will apply a monthly fee of $4.99 to individual developers accessing its SmartThings API. This decision directly affects advanced users who integrate devices with platforms like Home Assistant to customize their smart home. The company aims to fund improvements to its ecosystem, but the new cost will fall on those who rely on unofficial technical configurations.

Technical Impact on Home Assistant Integration 🔧

The SmartThings API allows developers to connect Samsung appliances and sensors with local automation systems like Home Assistant. Until now, this access was free for non-commercial purposes. With the monthly fee, users who sync multiple devices or use advanced features will need to assess whether the cost justifies the convenience. Alternatives like direct Zigbee or Z-Wave connectors could reduce reliance on this paid API, although they require additional hardware.

Paying to Turn on the Light, the New Tech Luxury 💡

Samsung invites us to pay $5 a month for the privilege of having our robot vacuum talk to the door sensor. Soon, turning off the light from the couch will be a premium service, and asking the assistant to play music might require a subscription. Meanwhile, Home Assistant users are doing the math: maybe going back to the manual switch isn't such a bad idea, at least they don't charge for touching it.
