Atrium IIoT Gateway User Guide

01Introduction

The Atrium IIoT Gateway is an industrial edge device that receives data from your NCD wireless sensors over a long-range wireless mesh network and turns it into a live, browser-based monitoring platform called Atrium.

What is Atrium?

Atrium is a local web dashboard for monitoring wireless sensor networks. It runs entirely on the gateway — data ingestion, the local database, the API, and the web interface all live on the device. There is no cloud connection required; the internet is only needed if you choose to enable Remote Access, push data to an external MQTT broker, or send email alerts.

Open a browser on any device on the same network as the gateway, sign in, and you get real-time visibility into every connected sensor: current readings, health status, historical charts, alerts, automations, scheduled reports, and a suite of industrial apps for productivity, OEE, energy, and environmental monitoring.

Offline & router capabilities

Atrium is built to run without an internet connection. Because data ingestion, storage, dashboards, alerts, and automations all execute on the gateway itself, your sensor network keeps collecting and recording data even when the site is fully offline — the internet is only used for optional cloud features (Remote Access, MQTT push, and email alerts), which resume automatically when connectivity returns.

The gateway also doubles as an industrial network router, so it can provide connectivity in the field rather than depend on existing infrastructure: dual Ethernet (WAN/LAN), dual-band Wi-Fi (access point or client), and optional cellular with automatic SIM detection for backhaul or failover, plus configurable firewalls and VPN for secure remote access. A single gateway can receive your wireless sensors, host Atrium, and route the local network at the same time.

02Hardware & What’s in the Box

Your gateway is built on the EG5120 industrial edge platform. Everything you need to get on the air is included in the box.

In the box

• Atrium IIoT Gateway unit (pre-loaded with the Atrium software platform)
• Long-range wireless radio module for your selected frequency
• Frequency-specific antenna (868–900 MHz or 2.4 GHz dipole)
• U.FL to RP-SMA pigtail cable adapter
• Power supply (9–60 VDC input)

Ports & connectors

Antenna connections

The gateway has multiple antenna connectors. Attach each included antenna to its matching connector as shown below — the long-range wireless (sensor radio) antenna, plus Wi-Fi and cellular antennas if those radios are used.

Wireless frequency options

The gateway is ordered with one long-range wireless radio to match the frequency of your NCD sensors and your region. Sensors and gateway must be on the same frequency to communicate.

Full gateway capabilities

Because it is the Enterprise IIoT Gateway underneath, your Atrium gateway is a full-featured industrial edge device even before you open Atrium. All of the standard gateway capabilities are available to you:

03Physical Setup & First Access

Get the gateway powered, on your network, and logged in for the first time.

Connect the hardware

1. 1
   Attach the antenna

   Connect the wireless radio antenna using the included U.FL to RP-SMA pigtail. Position it vertically and away from large metal surfaces for best range.
2. 2
   Connect to your network

   Plug an Ethernet cable from your LAN / router into the ETH0 port. A wired Ethernet connection to your local network is required to reach the Atrium dashboard. (Wi-Fi and cellular serve the gateway’s own internet uplink, not local dashboard access.)
3. 3
   Apply power

   Connect the included power supply (9–60 VDC input). The gateway boots and the Atrium software starts automatically — allow a minute or two for services to come up.

Open Atrium in a browser

On any device connected to the same network, open a web browser and navigate to the gateway’s address. Atrium is served on the standard web port, so no port number is needed:

http://<gateway-hostname>
# example
http://ncd-d8fc.local

If .local hostname resolution isn’t available on your network, use the gateway’s LAN IP address instead (you can find it from your router’s device list, or later on the Settings page under Gateway Info).

Log in

You’ll be presented with a login screen. Sign in with the default credentials shipped with your gateway:

04First-Time Setup Wizard

The first time you log in to a new gateway, a guided Setup Wizard walks you through initial configuration in about two minutes. A progress bar tracks six phases: Welcome, Email, Security, Access, Sensors, and Done.

Watch: Atrium Setup — Onboarding Sensors

Every step is optional — you can skip any individual step or the entire wizard, and change everything later from the Settings page. The wizard covers:

The six phases

05Navigating Atrium

After logging in, a top navigation bar gives you access to every area of Atrium. The gateway name, platform version, and current date/time show at the top of every page.

The navigation bar

The Sensor List (home page)

The Sensor List shows every device registered with the gateway. At the top, a Fleet Health Summary bar shows a live count of devices in each state — each badge is clickable to filter the list:

• Healthy — communicating normally, no issues
• Warning — a sensor error, low battery, or weak signal
• Offline — the device has stopped reporting

Use the toolbar to filter by sensor type, location, or status, or free-text search across device ID, location, asset, and name. Click any column header to sort. All filter and sort states are saved in the URL, so you can bookmark or share a filtered view — and when you open a sensor and press Back, your view is restored.

06Sensor Dashboards

Click any device in the Sensor List to open its dashboard — detailed, real-time information for a single sensor.

What’s on the dashboard

• Device header — name, device ID (MAC), sensor type, firmware version, location/asset, and a color-coded Last Heard timestamp.
• Status banners — amber warnings (sensor error, low battery, weak signal) or a red offline banner when applicable.
• Status History — a collapsible, chronological log of every health transition, useful for post-incident review.
• Time-series charts — one per metric, with selectable ranges (1h, 6h, 24h, 7d, 30d, or custom). Drag to zoom; drag charts to reorder.
• Thresholds — draw an alert reference line on any chart with a condition, value, and swing (hysteresis).

Vibration sensors add an FFT View for frequency-domain analysis and a one-shot Raw FFT Data capture. Sensors on the wireless mesh network show a Mesh Route Map with hop count and a link to the full network topology.

Configuring a sensor

The Configure link opens a tabbed editor where you set the sensor’s location, asset, friendly name, install date, report interval, and offline-alert preference; customize how each metric is displayed (formula, unit, label, visibility); and adjust sensor-specific parameters.

Interactive Preview

The panel below simulates the Atrium Sensor Dashboard for this Vibration / Temperature sensor. Data updates every 5 seconds to demonstrate the live monitoring experience.

07Custom Dashboards (Monitor)

The Monitor page is a customizable, widget-based view for watching multiple sensors at a glance — ideal for a wall-mounted display or a dedicated monitoring station.

Widgets

Click + Add Widget, choose a type, then add one or more sensor metrics with the Add Metric wizard. Available widgets include Line / Area / Bar charts, Gauge, Tank Level, Stat Card, Sparkline, Metric Card, and Table.

• Thresholds — Metric Card, Gauge, and Tank Level widgets support color-coded value bands. Use Auto-fill Zones to generate red/orange/green ranges.
• 4-20 mA scaling — for analog inputs, a built-in workflow maps 4 mA and 20 mA to real-world units (feet, PSI, gallons, and more).
• Synthetic Variables — computed metrics that combine readings from one or more sensors using a formula, available to any widget.

Drag widgets to rearrange them, resize by the corner handle, and click Tidy Up to auto-arrange. Layouts save automatically. A global time range panel controls chart-based widgets, and a Fullscreen button expands the page for shop-floor displays.

08Alerts, Automations & Reports

Turn raw readings into action — get notified when something crosses a limit, switch a relay automatically, and receive scheduled summaries by email.

Alerts & automations

The Alerts page has four parts:

• Alert Templates — threshold rules that auto-apply to groups of devices (all devices, a sensor type, a location, or an asset). New matching devices inherit the alert automatically.
• Triggers — a single threshold condition on one device’s metric, with a condition (above/below), value, and swing (hysteresis).
• Automations — link one or more triggers to one or more actions. When all triggers are active, the automation fires.
• Alert History — a searchable log of past alert events.

An automation’s actions can send an email to one or more recipients or command an output device (relay/actuator) — firing on trigger, on clear, or both. Each automation shows a live ACTIVE / OK status.

Scheduled reports

The Reports page generates and emails recurring reports (daily, weekly, or monthly) as PDF, CSV, or both. Report types include Fleet Summary, Sensor Group, Alert Digest, Productivity Summary, Custom SQL, and an OEE Summary (coming soon, alongside the OEE app). Use Send Now to test a report immediately.

09Apps

The Apps page provides specialized tools built on top of your sensor data. Productivity Monitor is available now; the remaining apps are coming soon and will unlock in a future update.

Each app supports date navigation, auto-refresh when viewing today, drag-and-resize layouts, and a Fullscreen mode for floor displays. Productivity, OEE, and Energy share machine definitions, so a machine configured once can be tracked across all three.

10Gateway Settings

The Settings page holds all gateway configuration. Read-only Gateway Info at the top shows the MAC address, LAN IP, and platform version.

11Troubleshooting

Quick fixes for the most common issues.

Factory Reset

A factory reset restores the gateway’s network settings and Node-RED configuration to their defaults. Use it as a recovery step if the gateway becomes unresponsive or stops booting normally, or when you want to start from a clean configuration.

1. 1
   Disconnect cables

   Remove all Ethernet and USB devices from the gateway.
2. 2
   Power on the gateway

   Apply power and wait a few seconds for it to begin booting.
3. 3
   Press and hold RST

   Press and hold the RST (reset) button — shown below — for 5 to 10 seconds.
4. 4
   Watch the RUN light

   The RUN indicator light will begin to flash rapidly. This confirms the reset has started.
5. 5
   Release RST

   Release the button. The gateway performs the factory reset and restarts — allow about 2–3 minutes before the interface is reachable again.
