Osum

Osum makes smart switches and home automation hardware for controlling lighting, air conditioning, curtains, and more. Their switches replace standard wall plates and connect to a mobile app, letting you adjust lights, set scenes, and monitor energy use from your phone. The lineup includes relay switches, dimmers, RGB controllers, scene controllers, and touch panels in several design lines (Smart, Luxe, Sense, Click).

What sets Osum apart is its decentralized architecture — each switch works on its own without needing a central hub. The company also claims the world’s first DALI/DT8 scene controller for precise lighting control, human-centric lighting that shifts color temperature throughout the day, and compatibility with Google Home, Amazon Alexa, Siri, and IFTTT. You can also control your central AC and motorized blinds through the same app and voice commands.

Osum is best for homeowners who want a reliable, hub-free smart home system, interior designers looking for flexible lighting options, and electricians or builders who need a straightforward installation. It’s a solid choice if you want to upgrade your home’s controls without getting into complex hubs or proprietary ecosystems.
