Vigilant Software Update


The Vigilant Battery Monitoring system receives periodic updates which can be installed by the end user. Updates are installed on the Vigilant Monitor via the Web-Interface. As of version 1.3.10, each system must be updated directly on the web-interface sequentially. This means if updating from 1.3.8 to 1.3.10, you must first update from 1.3.8 to 1.3.9.

Eagle Eye also offers a service to perform updates. If interested, please request a quote here.

Released Dec 27, 2022


  • Added a new log-in page
  • Modbus updates. Please review the updated mapping documentation for more detailed information:
    • Modbus has been updated to provide more information via the MEI types (Modbus mapping version & battery name).
    • Existing MEI data has been updated. Please review the mapping document to determine if the changes will affect you.
  • Minor improvements made to the discharge sections on the web UI:
    • Added the ability to download CSV files from the discharge page and discharge summaries page.
    • Improved legend display – will now be more compact on a larger range of screen sizes.
    • When hovering over the chart data, the web UI will now display the unit number alongside the values.
    • Discharge summaries now display the length of the discharge.
  • Improvements made to the web UI reporting systems:
    • Users can now download PDF versions of NERC reports.
    • Now when downloading CSV files and opening them in Microsoft Excel, it will recognize the correct file encoding and display the correct units in the headers.
  • Bar charts now allow users to zoom & scroll – particularly useful with systems with a large number of units.
  • When sensor communications are “idle”, the Vigilant will continue to communicate to prevent v2 boards from triggering a watchdog alarm.


  • Changes made to the Vigilant’s self-reporting version code.
  • Fixed a bug where the hysteresis/deadband deactivation variables were incorrectly set if adjusted from the web UI.
  • Fixed the Modbus MEI type data where one of the registers was accidentally duplicated.
  • Fixed an issue with the ELM management code (post-install) that would not register ELM alarms for any ELMs configured after commissioning (1.3.9 issue only).
  • Fixed an issue with historical ELM alarms, where all alarms would erroneously record that all alarms started at the same time.
  • Fixed an issue when LEDS/relays wouldn’t trigger when the system detected an alarm under certain circumstances (1.3.9 only).
  • Various improvements made to the installer to speed up the commissioning process.
  • Some minor typographical fixes in the web UI.
  • Some minor typographical updates to historical changelogs.

Released Apr 8, 2022


  • Post install wizard electrolyte sensor management. Users can now calibrate and reset all ELM sensors simultaneously.
  • Relay 2 is now reserved for watchdog (power) alarms. Once the Vigilant monitor is running – it will activate the relay. This relay will drop out in the case of power loss.
    • The relay will be activated at program start.
    • The watchdog will be patted once a minute in case the delay accidentally de-energizes.
  • Users can now change their temperature display preferences post install.
  • New Modbus data points added:
    • Average unit voltage
    • Average post temperature (Celsius & Fahrenheit)
    • Average unit resistance
    • Average STRAP resistance
  • Files downloaded from the Vigilant now have a more descriptive filename.
    • Reports specifically are named after the battery asset and time of report generation.
  • Changes made to the BMS reporting:
    • Added a new kind of report based on the existing NERC report, this is called the Monitor Report. The monitor report will increasingly diverge from the NERC report over time in future versions. Contains additional information that will be of interest to the user, but is not strictly to do with NERC.
    • Monitor report
      • Unexpected restart count
      • Removed some duplicated information required by different standards
      • Display system serial #
      • Can display web/docx/csv reports in the same manner as the NERC report
    • NERC report
      • On the “Battery & Strap Data table” – in the strap resistance column, non-strap points will now display the interconnection type and not “n/a”
      • System will still display “n/a” if there is no interconnect being monitored
      • Added a page where the user can add handwritten/typed notes to the end of a NERC report
      • Added report version
  • Engineers can now remotely disable/enable ground fault checking without being physically on-site via the web UI.
  • Unit interconnections can now be updated post-install.
  • Update page is now navigable from the actions page.
  • Non-topographical information (such as the battery name) can be edited post install.
  • Minor typographical improvements made.


  • Fixed a bug that would sometimes cause discharge events to be incorrectly split into multiple events after around 7 minutes.
  • Improved the resilience of the ambient temperature hot-swapping functionality that could prevent ambient temperature readings from being taken.
  • Fixed a bug with 6V nominal blocs where the resistances around out by a factor of 10.
  • Fixed a bug where the NERC csv is always displayed as being Celsius.

Released Dec 10, 2021


  • Made improvements to the Vigilant Modbus system:
    • Added some new experimental mapping points:
      • (binary) ground fault
      • (binary) self reported modbus error
      • (binary) sensor electrolyte level alarms
      • (register) end up of successful update timestamp (2x registers)
    • Modbus should no longer block clients while updating the registers.
    • Modbus should be better at running when the DB is inoperable (as long as it was activated beforehand)


  • Multiple string systems should now correctly calculate their battery voltage alarm levels.
  • Fixed the following issues with the Modbus module:
    • Ambient temperature would load the oldest data instead of the newest data.
    • Unit ripple is now functioning correctly.
  • Under certain circumstances, the default sorting for additional (non-unit) sensors on the battery page would be incorrect.
  • When no cable or intertier interconnect resistances were configured for a system, the web & docx NERC reports would display an empty section. This section is now omitted.
  • Under certain circumstances, a ground fault would not be detected.
