To view your current eGauge integration details, statuses, or unique MAC addresses, go to Settings on the left side menu, select Integrations, then select eGauge.
Overview
An eGauge is an integrated piece of hardware that uses an ethernet network connection to push real-time data to Atrius while monitoring an electrical load via current transformers (CTs) connected to a distribution panel. eGauges serve as both electrical meters and gateway devices.
eGauge devices are used when electrical meters are not already present or easily connectable to the Internet. They provide granular data from 15-minute up to 1-minute intervals and can measure up to four 3-phase power loads per eGauge. The meter measures the resource via the CT, stores the values internally, and pushes that value and timestamp to Atrius using HTTPS POST with CSV data format.
Integration Type: File-Based CSV Push via HTTPS POST
Prerequisites
Before beginning the installation, ensure you have:
Network cable with appropriate specifications
Ethernet port with external IP access for local web UI
Access to eGauge UI (local or cloud access)
Admin access to Atrius
eGauge configured with real-time measurements
Internet access for outbound HTTPS traffic (port 443)
eGauge user manual
Licensed electrician (for EG4xxx power installation)

Installation and Setup
Hardware Installation
⚠️ Warning: Power installation for EG4xxx models must be implemented by a licensed electrician.
Turn off power to the panel where the eGauge will be installed
Mount the eGauge securely inside or near the electrical panel
Connect voltage reference:
Connect hot, neutral, and ground from the panel to voltage terminals on the eGauge
Terminals are typically labeled L1, L2, and N
Install CT coils:
Clamp CT coils around the conductors to be monitored
Ensure the arrow on the CT points toward the load (direction of current flow)
Match each CT to the correct input channel on the eGauge
Secure CTs using their clips or fasteners
Connect CT leads to appropriate input terminals per the model wiring diagram
Double-check all wiring before restoring power
Power on the panel and verify eGauge is online (via LED indicator or network access)
eGauge Device Configuration
Locate device information:
Find the Device ID on the side sticker (format: eGauge123456)
Note the default username and password on the same sticker
Access the eGauge UI:
Local access:
http://egaugeXXXX.local(replace XXXX with Device ID) or via static IPCloud access: https://www.egauge.net/eguard/find/
Initial login:
Log in with admin credentials from the device sticker
You will be prompted to change the password on first login
Configure Data Sharing:
Navigate to: Setup (top left) → View → Classic View
Go to: Settings (top right) → General Settings
In the Data Sharing dropdown, select Atrius
No changes required for other fields
Select Save → enter eGauge device username & password → select "send anyway" on unsecure site warning
✅ Success indicator: When the meter is successfully configured, you will see a confirmation message: "Data sharing to Atrius has been configured successfully"
Configure sensors and registers:
Navigate to: Setup → Classic View → Settings
Set Sensor Type for each channel based on CT amp rating
Configure the Registers and assign proper power equations to calculate kW
Refer to eGauge manual for recommended equations
Rename the kW usage register as needed for easy identification
Verify kW usage values are displaying correctly
Click Save
Atrius Integration Setup
Access Atrius:
Log into Atrius: https://buildingos.com
Navigate to: Settings → Integrations → Add an Integration
Direct link: https://buildingos.com/services/connect
Add eGauge integration:
Select the eGauge integration icon and click Add
Enter
eGauge[DeviceID]and click ConnectExample:
eGauge12345(if Device ID = 12345)
Platform Access & Point Mapping
Access Discovery:
Navigate to: Integration → eGauge → Discovery
Direct link: https://buildingos.com/meters/service/41/available
Wait for data points:
Allow 5–15 minutes for points to arrive
Refresh the page if points are not immediately visible
Connect and map points:
Click Connect for the desired kW register
Use unique names for easy identification in Atrius Point Discovery
Name the point according to your site's naming convention
Set metadata:
Meter Name (e.g., "Main Electrical Panel")
Units (e.g., "kWh")
Tags or zones (optional)
Save and activate:
Save mapping and activate the meter
Allow 5–15 minutes for data transmission
Data Validation
Test data transmission:
Use Preview in eGauge Data Sharing to confirm data transmission
Go to: Dashboards → Time Series in Atrius
Hover over data points to verify timestamps and values match eGauge readings
Cross-reference measurements:
Compare Atrius dashboard values with on-site eGauge screen readings
Validate that data appears in expected intervals (1-15 minutes)
Best Practices
Ensure outbound HTTPS on port 443 is allowed by firewall
Use a static IP or DHCP reservation for eGauge device
Backup eGauge configuration periodically
Re-verify meter mapping in Atrius after firmware updates or device resets
Use descriptive naming conventions for easy point identification
Regularly verify CT phasing and connections
Troubleshooting
Review common troubleshooting steps that may restore communication between an offline eGauge device and Atrius.
If an eGauge point is offline
Physically reboot the eGauge device
Verify network connectivity:
Ensure eGauge device has outbound connection to IP range:
20.59.7.16/29via http (port 80) or https (port 443)Check if recent network/firewall changes impacted communication
Verify power and hardware:
Confirm breaker is powering your eGauge device
Ensure eGauge device is connected to the network
Check LED indicators on device
Verify configuration:
Confirm data sharing is enabled and set to "Atrius"
Check that current transformers are configured properly with correct phasing
Verify the eGauge channel checker appears active
Common Issues and Solutions
No Data in Atrius:
Confirm Data Share is active (not in error state)
Validate firewall rules allow port 443 to
ftp.buildingos.comVerify timestamp formatting uses ISO8601 standard
Check eGauge device time synchronization
CSV Format Errors:
Ensure CSV columns are properly comma-separated: Timestamp, Meter Name, Units, Value
Verify data sharing configuration in eGauge settings
Missing Meters:
Confirm all meters are properly mapped in Atrius Point Discovery
Use Diagnostics → Raw Data in eGauge to confirm outgoing values
Check that Device ID matches exactly in Atrius integration setup
Connection Issues:
Verify eGauge has stable ethernet connection
Check if DHCP lease has expired (consider static IP)
Confirm DNS resolution for Atrius endpoints
