Demo
Industrial monitoring on a compact local HMI
A demo application for Elecrow CrowPanel ESP32-P4 v1.2, modeling a beverage production and bottling facility and showing how LoRaWAN telemetry can be turned into useful process-level information.
On the main screen, the operator sees the entire facility, the number of available devices, warnings, and active alarms. From the overall view, the operator can open a specific production zone and then drill down to an individual piece of equipment.
Equipment condition and connectivity are monitored separately. Loss of communication with a sensor does not automatically mean the equipment has stopped: the HMI retains the last received value and clearly indicates that the telemetry is stale.
During a fault scenario, the system shows how the problem propagates through connected areas and equipment and guides the user toward the root cause.
For each piece of equipment, the interface displays:
- ✓Current condition and operating status
- ✓Connectivity status and time since last telemetry
- ✓Current measurements and operating ranges
- ✓Parameter trend charts
- ✓Active warnings and alarms
- ✓Links to related process elements
Navigation model
From site overview to root cause
The HMI is organized in three main levels, allowing the operator to move from overall plant status to a specific device without losing process context.
02
Zone Overview
Combines the physical process structure with the live state of equipment, making it easy to see whether a problem is isolated or affects a larger part of the process.
03
Equipment Detail
Provides operating state, LoRaWAN communication state, measurements, expected ranges, historical trends, alarms and relationships with other equipment.
Key design principle: equipment health and communication health are handled separately. A device can remain operational while its LoRaWAN connection becomes stale or offline.
Telemetry & trends
See not only the value, but how it got there
Current values are displayed together with operating ranges, recent history and telemetry age, helping the operator understand how a parameter reached its current state.
The operator can compare:
- ✓The current value
- ✓The normal operating range
- ✓Recent trend behavior
- ✓The age of the latest telemetry
This makes the interface useful not only for detecting an alarm, but also for understanding the process conditions that led to it.
Instead of displaying LoRaWAN endpoints as a flat list of sensor values, the HMI keeps devices connected to their role within the production process.
Fault scenarios
Follow a problem through the process
The prototype includes 10 predefined fault scenarios that can be triggered directly on the panel. They demonstrate how a fault can affect several connected parts of the process.
Low raw-material level
Pump degradation
Flow restriction
Incorrect valve position
Telemetry loss
Cooling-system overload
Unstable mixing
Packaging-line shutdown
Cold-storage door left open
Drainage-pump failure
Instead of presenting isolated alarms, the HMI shows relationships between affected equipment and lets the user trace the issue until the underlying cause becomes clear.

Customization
From Demo to Your HMI
This demo is a concept prototype rather than a production-ready industrial deployment. All devices, telemetry and fault conditions are simulated, so the concept can be evaluated without deploying a real LoRaWAN network or dozens of physical sensors.
The same approach can be adapted to your equipment, process structure, data, control commands, UI, branding, alarms, operating scenarios and required integrations.
Customization can include:
- ✓Your equipment and system structure
- ✓Your data and control commands
- ✓UI and branding
- ✓Alarms and operating scenarios
- ✓OPC UA and other required integrations
- ✓CrowPanel hardware configuration
