GEZINSMAN.NL mission is to support family processes with technical solutions and is a full-stack integrator of embedded and cloud systems.

That sounds nice, but what do you actually do?

We stand for a smart society, to which we will contribute as much as possible by means of affordable technical solutions.

Now its even getting crazier. What does that mean for me?

  • We start at your home by making the rooms smart. We do that by integrating sensors, actuators and a smart controller in each room.
  • After that we make your home smart by the collaboration of the individual smart rooms.
  • Next we will make your family smart. We do that by producing and hosting smart cloud solutions, which will support the collaboration of family members with eachother and with the house.
  • Finally we aim for a smart society, by creating cloud solutions, which support the collaboration of individual families.

That sounds very nice, but how are you planning to do that and what will that cost me?

We make use of open source software and affordable, but reliable single board computers. In this way, we manage to keep development costs low, while maintaining a high efficiency and quality. This means for the customer, that he will not pay the grand prize, which one normally pays for a professional wired domotica system, but a price, which is comparable to the amount one would pay for e.g. an internet/tv subscription. On top of that the smarthome can be regarded as a private cloudservice, which is tightly integrated with the gezinsman.nl cloud services, which has a number of convenient added values.

But is your solution just as reliable?

Our smarthome product uses the same distributed architecture, which is also used in medical and defense systems. In this architecture, the functionality is divided over multiple devices. This is because of the kind of application, for which these systems are used. These kind of applications need to operate at any time and under all circumstances. If this is not the case, it could result to serious damage and can be even be fatal.

By setting up the architecture of the smarthome in the same way, a high reliability can be achieved, despite the fact that inexpensive single board computers are used! Every room has its own local control. If this control malfunctions, then only the control for one room becomes not operational. The rest of the smarthome remains operational. And if the central controller (i.e. the smartbrain) malfunctions, then the rooms can still be controlled locally.

The smarthome synchornizes its data with the gezinsman.nl cloud servers. This is done with the same techniques, which is als used by NATO to share intelligence data among its allies. This makes it possible to control the smarthome and the other gezinsman.nl cloud services diensten any place in the world, without opening an external port in the router of your home network!

And do I have to pay for the gezinsman.nl cloud services?

No. The gezinsman.nl cloud services are entirely free of charge for all families. We can keep these services operational with the revenues from our smarthome product. The customers of our smarthome product pay for extra comfort and luxuary and keep our cloud services operational. Besides that, we make use of open-source software and a cluster of affordable virtual servers (VPS), which will keep the total operational costs low, while maintaining a high quality level.

So you're actually a kind of modern Robin Hood: You steal from the rich and divide it amongst the less well-off.

More or less. However, I sell a product/service to property owners, which gives an added value to their property. And often is it about those kind of homes, that actual could benefit from a professional home-automation system. So it is actually a win-win-win situation: Home owners will get a luxuary home, non property owners will benefit from a smart society and gezinsman.nl will earn some money to fund its R&D activities.
