Overview
-
Data Storage: Metering data is stored on the eGauge; the proxy server only relays data for remote access. Meters function normally without an Internet connection.
-
Access Methods: Meters can be accessed directly via local network IP/hostname or through the eGauge proxy server (e.g., https://eGaugeHQ.d.egauge.net or https://eGaugeHQ.egaug.es). To use a local IP or hostname, you must be on the same network.
- Encrypted Connections: EG4xxx meters support encryption. Older models (EG30xx, eGauge2) do not support encrypted proxy connections but allow HTTPS between the proxy and the browser.
Disabling Proxy Server
To disable the proxy, go to Settings → General Settings and set Proxy-server hostname to 0.
Note:
This will remove the ability for any sort of remote access or troubleshooting.
Proxy Server Access
- The proxy server connects meters to clients without needing router changes. The server keeps the meter’s IP anonymous, and data requests are handled entirely by the proxy.
- EG4xxx devices connect via TLS 1.2 on port 8084, while legacy devices use port 8082 without encryption.
- Public visibility: Meters without a site-wide password are visible on the "Find my Device" page at egauge.net/eguard/find/. To hide them, enable password protection under Settings → Access Control.
Security
- Access Control: Protect data with a site-wide password. For accounts with remote admin permissions, use strong passwords.
- Authentication: Proxy servers use hostname and key-based authentication to prevent unauthorized meter access.
HTTPS Support
- EG4xxx meters support HTTPS on local and proxy connections with TLS 1.2 (proxy uses TLS 1.3). Custom SSL certificates are also supported.
- Disable insecure local HTTP access via Settings → Network Settings.
Legacy Meters
Legacy models (eGauge2, EG30xx) lack HTTPS on the proxy. Use secure configurations for passwords, as these models use HTTP digest authentication.
