Known Issues

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

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

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.

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.

Resolved in firmware >= 1.1098 on WattmonPRO and >= 2.1098 on WattmonMEGA
