Aragon is the first voice control system for Home Automation that works without the need for an Internet connection. The Voice recognition runs entirely on the device – nothing is transmitted or recorded.

Your Privacy is guaranteed.

Offline Voice Control. Your privacy is guaranteed.

We’re home v2

We’re home!

Home automation has been developed to simplify our daily lives. Consequently, with a home automation system you can enjoy an increased comfort level, and will save a large amount of energy. Until recently, device control was limited to light switches, or to apps and tablets. However, this is not the most optimal solution for every situation in the home environment. Voice Control offers a superior, and far more convenient solution.


Aragon is here to simplify Home Automation in a safe and reliable manner. Voice Control is the most natural way to interact with a Smart Home.  Particularly, the advantage that Aragon has over other home automation systems is that you do not have to give up your Privacy.  Above all, Aragon is Private-by-Design.


Your home obeys your voice and the assistant helps you handle your everyday tasks. Most importantly, it keeps your hands (virus) free.

Automation the easy way with Node-RED - no programming skills required.

You come home from holidays. Usually, you need to take time to walk around the whole house, turning on the lights and opening the shutters. Instead, you can simply talk to Aragon. Just say, “Hey Snips, I’m home.” The lights will turn on and the shutters will open automatically, saving you a job.


You are in bed and realize that you have forgotten to turn off the lights in the living room. Instead of having to summon the energy to get up again, you can simply say, “Hey Snips, turn off the lights in the living room” from the comfort of your bed.

Private by Design

What’s said at home stays at home.


Online voice assistants are revolutionary.  They make our daily lives much easier.  However, we are all concerned about the privacy issues being compromised with the use of cloud-based assistants.  We have also all discovered that owning an online assistant makes us very dependent on maintaining a working Internet connection. The complexity of setting up an account just to use the cloud-based service, or to install special applications in order to use the device makes owning an online assistant daunting for the average customer.


At ProKNX, we have decided to take another path to help you, the user.  With you in mind, we have developed an offline voice control system for Home Automation that runs purely on the device.  We have made sure that the focus of our design is Privacy and Robustness. Since Aragon works offline, no data is stored; no data is transmitted to the cloud. Your privacy is guaranteed.


In summary, you enjoy many advantages from our offline approach. As a result, no automatic and silent updates will impact your installation. You decide, when, and if you want to update.


Why choose an Offline Smart Assistant?

Offline Voice Control. Your privacy is guaranteed.


Office v2

Aragon for Office

What’s said at work, stays at work


Aragon automation is here to simplify life, increase comfort, and save energy. Until recently, appliance control was limited to needing to physically use switches, or apps and tablets to activate devices. This is generally not the most optimal solution for streamlining actions needed to create the right environment. Being able to use touchless Voice Control is often a better and far more convenient way to manipulate your surroundings and create the perfect ambiance. 


With only one voice command you can effortlessly change the brightness of your lighting, or make sure that you are saving energy by turning off all the lights . When you walk out the door, one command does everything for you. Most importantly, it keeps your hands (virus) free.  For the office environment, Aragon units are already available.  The specialized solution of Aragon for Office is under development, and will be able to be deployed in the near future.


Powerful and discreet v2

Powerful and Discreet

There are thousands of alternative ways to give a command. To make your life less complicated, Aragon understands a large variety of vocabulary. It can initiate a single action when spoken to in many different ways.  It does the work for you so that you do not have to use a narrow range of words to turn on the lights, or open the curtains.  We firmly believe that our home automation system is stronger than those based in the cloud. Above all, we offer the possibility of customization, which sets us apart from the crowd.


Aragon is discreet because it is offline.  In addition, Aragon has been designed to be invisible in a room. In fact, Aragon is perfectly adapted to the design of your switches, as it measures a mere 55×55 mm.

Time is money

Plug-and-Play Installation

Installing Aragon with one of the Plug-and-Play Gateways could not be easier. It only takes five minutes, and requires no special knowledge. The only step needed is to connect the power and the network cable. After just a few minutes your system will be up and running and ready to use. Everything is configured automatically. In short, you will not waste your valuable time on having to configure the system, nor will you have to create online cloud accounts, or install applications and skills.

It is as simple as that!

Energy savings v2

Energy savings

One of the main advantages of home automation is the reduction of energy costs. With Aragon, it becomes even easier. With only one voice command you can effortlessly adjust the thermostat, and make sure all the lights are turned off.  When you walk out the door, one command does everything for you.


Easily check your consumption even when you are away, with the energy chart.


By choosing an offline system you are not only saving energy costs, but also reducing your carbon footprint. In one year, an Echo Dot produces the equivalent of 15.9 kg of CO2 in a year,  due to the energy it needs to interact with the cloud.

Smart Family Living v2

Smart Family Living – AAL

Help system for seniors and disabled people

Home automation has been proven to be very beneficial for people who are beginning to lose their autonomy.  With this in mind, we are convinced that with voice control and Aragon, we can go even further and allow people to gain back their independence. Consequently, with the aide of a voice-controlled home help system, everyday tasks become easier and require far less effort. By simply saying a short sentence aloud, such as “I’m awake”, Aragon will connect to a pre-programmed integration device, starting up a holistic scene by opening the curtains or shutters, and if needed, turning on the lights and turning up the heating. We want to extend the time that people can stay comfortably in the familiar environment of their homes.

Comfort is necessary to increase the quality of life, however, we understand that the biggest concern is safety. Thanks to Aragon, a nominated person outside the home can be contacted on their mobile phone as soon as an unusual event occurs. For instance, conspicuously long stays in a room,  e.g. the bathroom, are registered. The solo person is asked to confirm that he or she has no problem. If there is no confirmation in a set amount of time, a message is automatically sent to the named carer.

A help call can also be triggered verbally in case of a problem.


Why an Offline Assistant for senior-focused living is a good choice


More information

Monitoring and voice functions


Monitoring is supported by presence detectors that provide information on the duration of stay and absence in a room. As soon as an unusual situation is detected, the system sends a message to the telephone of the named carer.


Monitoring functions are offered:

  • Abnormal inactivity: when a programmed threshold time is exceeded
  • Late rising time: if the person does not wake up before a nominated time
  • Longer stay in the bathroom: longer than a specified duration
  • Unusual time to leave the apartment
  • Unusual time to come home
  • Long absence: when the duration is longer than a specified time


A sample of available voice functions:

  • Voice control of all functions for lights, shutters, scenes, and optionally, also media devices
  • Calls for help to nominated telephone numbers
  • Voice announcements from outside the home to the resident
  • Automated voice announcements to ask the resident to acknowledge a recognized problem situation
  • Voice announcements to act as a doorbell amplification

The classic help call can be triggered with the words “I need help”.  In this case a message is sent to the telephone of a nominated carer, to which he or she can then respond. The answer is again spoken over the loudspeaker of Aragon.
