====== Known Issues ======

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

===== Browser issues =====
==== 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 [[hardware:wattmons|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.
===== Temperature Sensor =====

In some situations, the Onewire temperature sensor does not give values when over 70 degrees celsius.
To solve this, edit /config/onewire.ini and add the line:
''presence_pulse_delay=50''
Under the ''[general]'' section.  Save and reboot, and it should work.  The default presence pulse delay is 35 uS.

===== Code issues =====
==== Blank Functions ====
//Resolved in firmware >= 1.1098 on [[hardware:wattmons:WattmonPRO]] and >= 2.1098 on [[hardware:wattmons:WattmonMEGA]]//

Blank functions cause errors in the [[hardware:wattmons|Wattmon]] parser, with the message ''Invalid } in file ...''.  

Example:

<code php>
function myFunctionThatFails() {
}
</code>
Fix:

<code php>
function myFunctionThatWorks() {
  $x=1;
}
