WinNUT should always show UPS values even if calibration is set to wrong values

WinNUT Version: v2.3.8988
Windows OS Version: Windows Server 2016 Essentials Build 14393

Describe the bug
Some values in the UI are displayed wrong although being provided correctly by the UPS. This has to do with "wrong" calibration settings. The range for battery.voltage was set from 6 to 18 volts but the UPS provided 27.1V. So the UI just displayed garbage values.

Maybe this has to do with some "old settings migration" – I don't know. I'm not sure if this was working before upgrading to the most recent version of WinNUT and I also don't know if the values were calibrated before.

To Reproduce
Steps to reproduce the behavior:

1. Set the calibration settings below the settings sent by the UPS
2. Apply
3. See wrong values being displayed in the GUI

Expected behavior
The value being provided from the UPS should always be visible in the UI – no matter what is set in the calibration settings. The gauge could be exceeded (or maxed out – whatever) but strange / wrong values should never be displayed instead.

Hi @codiflow ,

Thanks for taking the time to open this issue. I want to direct you towards a few others:

• Autodetect value ranges and gauge settings from UPS values #24
• Ability to overwrite UPS value (Enhancement) #69
• Stop substituting default/fallback values for UPS variables #116
• Gauges clamping to minimum when variable is unavailable #136

It sounds like this issue most closely related to #136 above and could take a little bit of work to do. Do you mind if I have you follow #136 so we can close this one?

[codiflow]

Sure – I will take care of maintaining my calibration section better in the future but maybe others don't (know that they should)?

The issue at #136 (and the others) are "the other way round" so there the value is not available from the UPS and therefore it displays the minimum value. For me the value IS available but it still is displaying the minimum value because the value exceeds the values set in the calibration section.

However you seem to be aware of this issue and others who might search for it here will come across this issue as well. So feel free to close it for now as the workaround is to check the calibration settings 😎

That's a good point you make too. I will leave this open now for other people to see. And here is a more specific issue where I intend to solve this problem if it helps at all. Thanks again for your work here!
