LiveView is normally accessed from the Live View page but it can be accessed full screen from here.

Diagnostic commands can be passed via the command line:

  • diagnostics=[1-4] Opens a diagnostics messages window. 1=all, 4 (default) = errors only
  • showallalarms=[on, off, toggle] Shows all alarm messages possible, or no messages or toggles them on and off every 30 seconds.


  • If you can’t see the latest version on the Live View page you need to clear your browser cache. Most desktop browsers respond to ctrl-shift-r. Android Chrome needs settings->advanced-privacy->clear browsing data (ensure you only check clear cached images and files or you will lose login details to other sites)
  • The information can be up to 2 minutes old as the data logger is on a 1 minute cycle and the LiveView internal refresh is also about 1 minute.
