About Alfa Controls

Alfa Controls was born in 2010 as a pioneering home automation project. Initially developed for its founder's residence, the solution evolved to become a robust automation platform, now applied in different residential, commercial, and institutional environments across various regions of Brazil.

Over the years, it has consolidated itself as a brand in constant evolution, seeking to unite technological innovation, energy efficiency, and reliability, always with the goal of simplifying people's lives and offering unique experiences of comfort, security, and practicality.

  • National technology: Solution developed entirely in Brazil, from hardware to software.
  • Energy efficiency: Equipment designed for reduced consumption, ideal for continuous operation.
  • Reliability: Robust architecture, based on quality components and stable protocols.
  • Scalability: Serves from small environments to large building automation projects.

AlfaNet – The Proprietary Network

The heart of the system is AlfaNet, a proprietary communication network developed specifically for automation environments:

  • Unifilar multi-drop topology (only one data wire + GND)
  • 9-bit serial communication at 4800 bps, with TDMA for access control
  • Support for up to 254 devices on the same network
  • Range of up to 500 meters with adequate cabling
  • Simple installation and high immunity to electrical noise

This approach ensures low cabling cost, reliability, and scalability in residential, corporate, and institutional environments.
