TWO CLEAR PATHS
Products & engineering. Research & experimental technology.
PICALLW separates production tools and custom development from research projects where hypotheses, methods and limitations are explicitly identified.
PRODUCTS & ENGINEERING
Software for real-world use.
Products and development for automation, HMI, business workflows, integration, data and reporting.
RESEARCH & EXPERIMENTAL TECHNOLOGY
Tools for testing ideas and patterns.
Research projects that distinguish measurement, interpretation, hypothesis and validation.
SOLUTIONS
From building systems to specialized software.
PICALLW combines building automation, integration and software engineering. Solutions are designed around the actual project: protocols, field devices, HMI, data, workflows and reporting.
Lighting, blinds and room automation
KNX-based room automation with DALI/DALI-2 lighting through appropriate gateways: switching, dimming, scenes, presence and daylight control, blinds/shutters, sun protection, weather logic and HMI integration.
DALI is presented here as a lighting subsystem integrated through suitable KNX/DALI gateways or controllers; this does not imply native DALI-bus commissioning in NODVIA Field.Building automation workflow →Business applications & system integration
Windows and web applications, SQL databases, APIs, reporting, document workflows and integration between technical and business systems.
Custom software →Local-first analytical software
Specialized tools for measurement, repeatability, longitudinal comparison, visualization and transparent research workflows.
GDV Studio →NEW PICALLW PROJECT · ANDROID
PICALLW Voice Studio
Cymatics, frequency generation, recordings and measurable acoustic voice features in one Android research environment.
TYPICAL USE CASES
From a problem to a usable tool.
These examples describe typical ways PICALLW technologies can be used and are not presented as customer case studies.
From field point to operational HMI
- Problem
- Multiple protocols, scattered points and time-consuming visualization setup.
- Solution
- NODVIA Field discovers and checks data, Studio designs the HMI, Cloud publishes it and View runs it on an Android touch panel.
- Technologies
- BACnet · Modbus · KNX · DALI gateways · M-Bus · Climatix · Android HMI
- Result
- A shorter, more traceable path from field diagnostics to a usable operator screen.
Data, users and reports in one workflow
- Problem
- Manual transfers, spreadsheets and information spread across disconnected systems.
- Solution
- A purpose-built web or Windows application with a database, users, API integration and automated reporting.
- Technologies
- Web · Windows · SQL · API · integrations · reporting
- Result
- One workflow, less manual re-entry and repeatable report generation.
Measurements gain context over time
- Problem
- A single measurement without context on quality, repeatability or the person's own baseline.
- Solution
- GDV Studio combines image analysis, comparisons and trends with optional HRV/ECG context.
- Technologies
- GDV/EPI · HRV · ECG · image analysis · longitudinal data
- Result
- More transparent comparison over time and clearer separation of signal, variability and interpretation.
