About Sensor Networks

Founded by Mark Allewell, Sensor Networks emerged from a visionary pursuit to revolutionize insurance claim processes. Initially exploring a key fob locator for vehicles, the company pivoted in response to insurer feedback, focusing on minimizing burst geyser claim costs. With a defined price point, Sensor’s team crafted a groundbreaking solution that transformed into a connected geyser offering—an aftermarket innovation retrofitted onto existing installations for heightened monitoring and automated interventions.

The connected geyser solution, featuring an array of sensors and a controller unit with motorized valves, seamlessly integrates with a user-friendly mobile app. This comprehensive system empowers users to adjust water temperatures, monitor electricity and water usage, and schedule activations. The resulting reduction in consequential damage on geyser claims streamlines insurance processes, with the company establishing a notable presence through seven appointed distributors, including major insurers like Nedbank. Sensor Networks envisions expanding its product line to encompass smart security, fire alarms, connected plugs, and more, further embedding itself in the connected-home ecosystem.

Value Proposition

Sensor Networks stands as a pioneering smart home management company, offering a unique ecosystem that empowers users to efficiently manage energy, security, and living conditions. The flagship connected geyser solution, endorsed by major insurers, reduces consequential damage on geyser claims, streamlining the replacement process. Integrated with service providers, Sensor Networks provides a centralized point of engagement, allowing customers to automate energy management and mitigate risks related to security, fire, and water damage. The company’s commitment to innovation, proprietary technology, and strategic partnerships positions Sensor Networks as a leader in simplifying smart-home management and enhancing overall customer value.
