VAKTEN · DIGITAL TWIN FOR EXISTING ASSETS

See what your equipment is actually doing right now.

VAKTEN shows what doors, gates, refrigerated areas and other technical assets are doing right now. HJÄRTA connects real sensors and existing signals to the digital twin – without replacing equipment that already works.

DIGITAL TWIN

Know what is really happening.

We developed a system that captures real conditions where they occur. HJÄRTA connects on-site sensors and existing signals to VAKTEN. Our software assigns these perceptions to digital twins, evaluates them against your rules and shows what matters for operations.

You can create any number of sensors and digital twins, link them together and have their states evaluated in a traceable way. Especially in existing installations, this quickly creates clarity about what doors, gates, refrigerated areas or other technical units are actually doing.

HJÄRTA and VAKTEN are designed so that real-world states become visible without technical guesswork — from installation through day-to-day use.

01 Reality

Reality

A door opens. A temperature rises. A contact changes state.

02 Sensors

Existing or supplementary sensors provide the technical perception.

03 Capture

HJÄRTA

HJÄRTA connects real-world signals on site to VAKTEN reliably and traceably.

04 Evaluate and inform

VAKTEN

VAKTEN shows the digital twin with state, history, rules, context and action required.

HJÄRTA in practice

Here you can see HJÄRTA in use and from the inside. HJÄRTA connects sensors and existing technical signals on site to the digital twins in VAKTEN.

Inside, modern microcontroller technology works with galvanically isolated 24 V sensor interfaces. Local operation and VAKTEN are multilingual — keeping the technology accessible without sacrificing industrial robustness.

Digital twin in VAKTEN

Here you can see a real digital twin in VAKTEN. The image shows the actual software interface in operation: current perception, assigned signals, rules, history as well as inspection and maintenance information — all in one context.

VAKTEN IN DAILY OPERATION

Stop searching. Know.

A digital twin answers a concrete operational question: What is the actual state right now? VAKTEN shows the answer immediately and traceably.

Closed · Within target
Door & gate

Is the door or gate actually closed?

No more assumptions or guesswork. HJÄRTA and VAKTEN provide the actual operating states of your monitored assets – visible, understandable and traceable, including opening duration, target times, cycles and deviations.

6,8°
≤ 8 °C
Cooling

One measurement. Multiple rules.

Temperature and door contact are evaluated together. This creates context instead of a flood of alarms.

Conveying

Blocked, occupied or simply quiet?

Light barriers and status contacts show whether an area is clear, occupied or blocked – making deviations traceable.

GUIDANCE EXCELLENCE

The user says what they want to monitor. VAKTEN handles the rest.

No programming. No frustration. No technical background required. The guided setup is designed to be intuitive. VAKTEN recognises hardware and sensor profiles, prepares the appropriate signals, suggests sensible rules and only asks when your decision is actually needed.

Complexity belongs inside VAKTEN. Clarity belongs with the user.

HJÄRTA · THE BRIDGE TO REALITY

Existing equipment does not need to be replaced to become visible.

HJÄRTA connects existing contacts, 24 V signals and matching sensor boxes to VAKTEN. It sits where technical truth originates: in the field.

  • Easy Access for prepared sensor boxes
  • 10 Professional I/O channels for existing signals and your own sensors
  • Local service interface and diagnostics
  • No intervention in existing safety functions

WHY VAKTEN EXISTS

It began with a simple question from fire protection.

A fire alarm system can report that something has been triggered. But where can an operator see whether the fire door is actually closed afterwards?

That gap first became an idea, then HJÄRTA, then VAKTEN. Hardware, firmware, backend and interface were not built from a pitch deck, but from a practical question: How can a real state be made visible so that people understand it immediately?

Today it has become a complete system – and it deliberately stays close to reality.

THE SIMPLEST START

Show us a state you still have to go looking for today.

A door. A cooling point. A conveyor line. Together we check whether it can become a useful digital twin in a short time.
