The story behind a graph

Behind every data point lies a story. Why does a sensor register a deviation? What is the cause, and how can we resolve it as effectively as possible? This time, we tell the story of a hot water registration in a sanitary building at a holiday park in Gelderland.

It was a beautiful Monday in September. After a warm, muggy day, the clouds began to gather for a massive thunderstorm, as often happens in the Netherlands. The day ended with thunder, lightning, and, as has been increasingly common lately, a lot of rain. The guests at the restaurant were comfortably indoors or snug in their caravans, waiting for the spectacle to pass.

Fortunately, the rain did not last long, and soon the clouds made way for a beautiful late-summer evening. But then, in the sanitary building, the fuses blew due to the thunderstorm — exactly the one for the group that the hot water boiler was on. The water temperature began to drop, and the showers slowly became colder and colder.

One of the guests, who was comfortably sitting in front of his caravan, decided it was time for a refreshing shower. He grabbed his towel, greeted his wife, and took a last look at the departing clouds. “After such a muggy day, a lovely shower is just what I need,” he thought. Whistling, he walked to the building and chose his favorite shower. Although all the showers were the same, he still had his favorite spot.

He undressed and turned on the tap. The water didn't feel very warm. “Oh, it will warm up soon,” he thought, but no, the shower got colder and colder. His mood worsened. With a frown, he turned off the tap and was about to stomp to the reception. But... thankfully this did not happen. Here’s what actually happened:

Because... a sensor from RecraPlan was connected to the hot water system. When the value dropped below the normal level, an alert was immediately sent to the technical service. An employee jumped into the club car, drove to the sanitary building, and inspected the technical room. “Aha, a fuse is out!” After resetting the power and checking the system, the hot water supply was quickly restored.

The man with the towel turned the corner and greeted the technical service employee. “Have a nice evening!” “You too, and enjoy a lovely shower,” replied the employee with a smile.
