Device homepage

Assessment available at all times

Each measurement device has an integrated web server, which has a separate homepage. The measurement device can be operated in the same way via its homepage as with the device display.

Furthermore, extensive current and historic measurement data, including the power quality analysis, can also be called up. An advantage of the device homepage is the constant availability of the measurement data – without prior software installation.

The user can immediately obtain an overview of all energy data. The device homepage can be displayed on any end device and will be adapted to suit the device functions (Responsive Design).

Simple operation is possible thanks to the uniform design of the GridVis® visualisation software and the device homepage.

Your benefits:

  • Access to powerful device homepage via web browser
  • Constant availability of the measurement data
  • No software installation necessary
  • Online data, historical data etc. can be called up directly via the device homepage
  • Function expansion possible through APPs
  • Remote operation of the device display via the homepage  Integrated PQ watchdog
  • Hyperlinks deliver more detailed information
