Gauges clamping to minimum when variable is unavailable #136
Description
Original post
updated from WinNUT Client v2.3.8800 to lasted version :
have Eaton 9E 2000i but seems don't have : battery.voltage variable
and have 6V instead of 12V like was in versions before :
Problem
When WinNUT tries to query a UPS variable on the NUT server, and it encounters an error e.g the variable is missing, it used to substitute the value with a nominal/expected value. Recently, WinNUT was changed so that when a variable is unavailable, instead of being set to a believable default value, it will now be set to an obviously out-of-range value (-1.) It's been discovered that the gauges will clamp themselves to the gauge's minimum value instead of displaying the true value, which is also misleading.
Solutions
When value is beyond the gauge's displayable range:
- Uncap display of value on the gauge face
- Graphical indication that the value is beyond the range of the gauge
- Gauge needle travels slightly beyond the gauge range
- A small icon to indicate that it's out of range
- Allow gauge to auto-scale its self to the input value(s)
When the value is unavailable:
- Lock needle below minimum, clear/reset value display, and show alert indicator
- Remove needle entirely
- Some or all of the gauge display is covered with an alert:
