Smart speakers like Amazon Echo, Google Nest, and Apple HomePod are central to today’s connected homes. They do far more than play music—they control lights, locks, thermostats, cameras, and appliances. But can you use a smart speaker with any smart home system in 2025? Is cross-brand compatibility finally a reality?

That's why choosing compatible smart plugs—especially when mixing brands—is key to building a smooth, reliable home automation setup.
