Which Android app should I use to connect and control different brands of smart devices in one place?

SmartThings is a central control panel for mixed-ecosystem smart homes. Its primary strength lies in its broad compatibility, functioning as a bridge for devices from Samsung, Philips Hue, Ring, and numerous other manufacturers. For the user with a smart TV from one brand, light bulbs from another, and a Samsung oven, the app creates a unified dashboard. Specific features like the ability to group devices into rooms, create automation routines, and control everything remotely via an internet connection address the core need for centralized management. Reviews indicate users appreciate the seamless integration, with one noting their 'TV is responsive with the remote' and they are 'amazed at the development and how it integrates seamlessly with appliances.' However, the setup process for some non-Samsung devices can involve multiple steps, and the interface, while generally clean, presents a learning curve with its many options. For a homeowner gradually building a smart home with purchases from various sales and brands, SmartThings provides a practical solution to avoid being locked into a single manufacturer's app. The ability to, for instance, start preheating an oven or checking if lights are off while away from home demonstrates its utility in real-world scenarios. Its limitations typically surface at the edges of compatibility or during initial configuration, but for core control of a diverse device portfolio, it remains a robust choice.
