Settings

The Settings page serves as the central hub for configuring the core parameters of your Fentrica edge device, including network connectivity, cloud integration, hardware behavior, and system maintenance.

Device Info

This section displays read-only metadata about your specific hardware unit.

Serial Number: The unique identifier for your device.
Model & Class: The hardware model version and device classification.
Flow Revision: The current version hash of the deployed flow configuration.
Fentrica Services Issuer: The identity string used for secure Fentrica services.

You can also configure custom identifiers to help organize your fleet:

Name: A human-readable name for the device (e.g., "Main Building Controller").
Location: The physical location (e.g., "Server Room B").
Description: Optional notes about the device's role or installation details.

I/O Configuration

This panel allows you to configure the physical inputs and outputs of the controller.

Analog Inputs (AI)

Configure each analog input channel based on the connected sensor type:

Mode: Select the input type:
- U (Voltage): For 0-10V sensors.
- I (Current): For 4-20mA sensors.
- R (Resistance): For resistive sensors.
- PT1000: For PT1000 temperature sensors.
Sensitivity: Filters out small fluctuations in the signal to stabilize readings.
- Suggested Value: 100 (Higher values provide more smoothing but slower response).
Alpha: A weighting factor for the exponential moving average filter, affecting how quickly the reading adapts to changes.
- Suggested Value: 0.1 (Lower values smooth the signal more significantly).

Digital Inputs (DI) & Outputs (DO)

Digital Inputs: View the status of digital input channels.
Digital Outputs: Configure outputs as potential-free contacts.
Relays (R): Configure mechanical relay outputs.

Zones

Configure alarm zones (Z0-Z6) for security integrations.

EOL Resistance: Set the End-of-Line resistance value.
Zone Resistance: Set the normal operating resistance.
Thresholds & States: Define the resistance thresholds that trigger specific states (e.g., Closed, Open, Short Circuit, Open Circuit).
Normally Open: Toggle between Normally Open (NO) and Normally Closed (NC) logic.

Fentrica Cloud

Manage the connection between your edge device and the Fentrica Platform.

Cloud Enabled: Toggle the connection to the cloud.
Cloud Key: The authentication key required to link this device to your Fentrica account.
Bench Environment Variables: When "Fentrica cloud management" is enabled, environment variables for your logic flows can be managed remotely via the cloud.

Network Interfaces

Configure the device's local network settings.

Interface Management: Add (New Interface), Edit, or Remove network configurations.
Configuration: Set up static IP addresses or enable DHCP (IPv4) for automatic assignment.

Software Update

View the current firmware version and install available updates with a single click. The system will automatically check for the latest stable release.

Bench Environment Variables

Define global variables in JSON format that can be accessed by your Bench flows. This is useful for storing API keys, configuration constants, or site-specific thresholds.

Example Usage: If you define a variable "SITE_ID": "bldg-101", you can access it in a standard Change node or Function node using the environment variable syntax:

Change Node: Set msg.payload to $env(SITE_ID)
Function Node: let siteId = env.get("SITE_ID");

Note: If "Fentrica cloud management" is active, these settings may be overridden by the cloud configuration.

Configuration Backup

Protect your setup by creating and restoring backups.

Create Backup: Download a snapshot of the current device configuration.
Upload Backup: Restore the device to a previous state from a saved file.

Device Management

Perform power actions on the device.

Reboot: Restart the device.
Reset Configuration: Wipe the current configuration and return settings to their factory defaults.
