Issues

Sometimes issues crop up, and we list them here with their solutions

Hover over graph on Wattmon in Firefox 52+

FireFox recently changed automatic detection of touchscreens when they released v52.0. This affects the hover values because FireFox won't show the hover values if it thinks a touchscreen is being used. To make a long story short, changing this configuration value fixes the problems on systems where FireFox thinks a touchscreen is enabled:

  • about:config
  • Search “dom.w3c_touch_events.enabled”
  • Modify value 2 → 0

Graph page does not show updated values

Sometimes browser caches cause graph pages in Wattmon to show older data. If you are on a graph page (battery status, energy in Watts) and you are seeing old data, press Ctrl + Shift + R to force reload the page.

Blank Functions

Blank functions cause errors in the Wattmon parser, with the message Invalid } in file ….

Example:

function myFunctionThatFails() {
}

Fix:

function myFunctionThatWorks() {
  $x=1;
}
