NODVIA by PICALLW
Universal Automation Platform
Connect. Integrate. Automate.
NODVIA is a family of building automation tools connecting field diagnostics, project data, HMI design, cloud delivery and operator visualization. Field, Studio, Cloud and View form one connected project workflow, while the modular Connect, Core, Logic and Edge layers extend the same model into integration and local automation.

ⓘ Why the name NODVIA?
NODE + VIA
Node represents a controller, device, meter or system. Via represents the path or connection between them. NODVIA therefore describes the core idea of the platform: connecting different nodes through different communication paths into a useful whole.

01 · FIRST PRACTICAL STEPCONNECT DIAGNOSE COMMISSION
NODVIA Field
The Swiss Army knife for building automation engineers.
An Android field toolkit for system integrators, service technicians and commissioning engineers. NODVIA Field brings common diagnostics and specialized service tools onto the phone already in your pocket.
Discover networks, devices and communication paths.
Inspect objects, registers, values, topology, trends and communications.
Perform supported writes and settings, save project context and create reports.
PRACTICAL HMI WORKFLOW
Field → Studio → Cloud → View
NODVIA Field, Studio, PICALLW Cloud and NODVIA View create one connected project workflow from field engineering to the operational Android HMI.
NODVIA Field
Discover. Diagnose. Commission. Collect real devices, points and service context.
Field →NODVIA Studio
Design the HMI from the project tree and manage Project ID, publishing, deployment and Cloud projects.
Studio →PICALLW Cloud
HTTPS project delivery, versions, SHA-256, QR deployment and license/seat context.
NODVIA View
Standalone fullscreen Android HMI for tablets and touch panels — without Field service menus.
View →NODVIA FAMILY
One concept, clearly separated roles.
NODVIA is not one monolithic application. The platform is divided into modules that can be adopted progressively according to the needs of the site.
NODVIA Field
Mobile diagnostics, commissioning and service. The first contact with devices and communications.
Explore Field →NODVIA Studio
Windows HMI designer and Cloud project manager: design, publish, Project ID, deployment, license/seats and Browse/Open Cloud Projects.
Explore Studio →NODVIA View
Standalone Android HMI visualization runtime for fullscreen tablets, wall-mounted touch panels and operator screens, deployed from Studio through PICALLW Cloud.
Explore View →NODVIA Core
Runtime, data model, configuration and shared platform services.
NODVIA Connect
Connectivity layer for BACnet, Modbus, MQTT and other protocols.
NODVIA Logic
Logic engine for conditions, timing, calculations and process rules.
NODVIA Edge
Gateway and edge layer for local integration and supervisory connectivity.
NODVIA Mobile
Mobile operational interface for fast use on phones and tablets.
IMPLEMENTATION STATUS
Where is NODVIA today?
The practical HMI workflow is now clearly separated between Field, Studio/Cloud and the standalone View runtime. The broader Connect, Core, Logic and Edge layers continue the platform toward persistent integration and automation.
NODVIA Field
The active first step. Android commissioning and service toolkit for discovery, diagnostics, project workflow and reporting.
Field →NODVIA Studio + Cloud
Built and under active testing. HMI design, Project ID, HTTPS publish, deployment, View licensing/seats and Cloud project browser.
Studio →NODVIA View
The new standalone member. Fullscreen Android HMI runtime for projects published from Studio through PICALLW Cloud.
View →Connect · Core · Logic · Edge
Broader platform layers in active development/testing. Protocol integration, runtime, logic and edge/gateway roles.
Practical deployment: Field → Studio → PICALLW Cloud → View. Wider automation: Connect → Core/Logic → Edge.
WHY NODVIA
Real buildings are not one protocol and one vendor.
A single site can contain BACnet, Modbus, KNX, M-Bus, Siemens Climatix, web devices and legacy equipment. NODVIA is built around that reality: first understand communication and data, then connect them into a stable automation system.
