The Challenge: Remote Management in the Pre-IoT Era
From 2006 to 2011, during the rise of mobile connectivity, there was a critical need for simple, fail-safe remote control of large-scale infrastructure. Businesses needed a way to reset power, disable leased equipment (like elevators), or monitor scientific sensors in remote maritime locations without expensive satellite links.
The Solution: The GSM Switch Series
I developed a line of independent GSM-controlled devices from scratch — from initial concept and PCB design to firmware development and final sales. These devices were built to do one thing perfectly: execute commands via SMS with 100% reliability.
Key features of my approach:
- Absolute Clarity: Unlike cheap mass-market alternatives, my devices came with comprehensive technical documentation.
- Component Transparency: I provided full details on every component used, ensuring industrial-grade stability.
- Versatility: The systems were used for everything from managing leased assets to mission-critical research.
High-Profile Recognition
The reliability of the GSM Switch was so high that even the Academy of Sciences chose this solution for monitoring autonomous marine research buoys. They prioritized my engineering transparency over cheaper, “black-box” competitors.
