Professionals who trust our solutions

Energy & Building Operations Manager

We have real-time monitoring of energy consumption and building systems, enabling operational optimization, reduced energy usage and faster data-driven decision-making to improve efficiency and system performance.

Electrical Distribution Operator

Real-time monitoring of our low-voltage network enables early detection of anomalies, prevention of transformer overloads and reduction of energy losses, improving grid reliability and operational efficiency.

Maintenance Director in Electricity Distribution Company

In the electrical distribution network I manage, monitoring systems have improved issue detection and resolution. We can identify faults early, supervise substations remotely and anticipate corrective actions, enhancing grid reliability and maintenance efficiency.

Wibeee Nest User

I achieved my goal from the first moment I connected it, which was to control the kWh I consumed daily and reduce them. Last year it consumed around 11 kWh per day and now, thanks to Wibeee, between 8 and 9 kWh.

FV Installer

With Wibeee, my clients can easily see the energy savings they achieve with solar panels, and they love it. Plus, for me as an installer, it’s a key tool that allows me to offer a more complete and reliable service, with clear, real-time data.

Distribution System Operator (DSO)

Visibility at transformer and feeder level has improved our grid capacity management. We can assess available capacity, anticipate congestion and approve new connections with confidence, optimizing network performance and investment planning.
