2 months ago @MaxMadcc I'm noticing that the calculation for power based on current and voltage (219.5*1.7=373.15) is quite a lot different than your output.realpower reading. Can you confirm which if any of the variables/calculations represents the true power draw of your UPS?

2 months ago According to the official manual and nut huawei-ups2000 driver. I think "output.realpower" is appropriate for reading values.
I think that in certain UPS, "output.realpower" may not be readable, so use P=I V 0.8 (note: PF).

2 months ago Thank you for finding that information! As I'm understanding it for now, it seems like output.power doesn't really have any use to us so I think I'll ignore that unless you have other ideas.
I'd like to propose a few tests if you wouldn't mind running them for me. I'm going to work on the power calculation method first so it supports your UPS, then I'd like you to give that build a try for me and report how it works. After that, I'll implement the direct reading from output.realpower as that seems to be the most convenient and accurate measurement available to us. Then I'd like you to test that and let me know how it works, then I'll have a pre-release up.
Let me know what you think about this.

2 months ago Just put up a new debug build here, please download and test when convenient. This should cause WinNUT to calculate power based on your UPS's output voltage and current only. More direct variable reading will come in the future.

Thanks for your build.
It seems to need round 1 or 2 number to the decimal places.

I'll try using NUT/upsd to put up a virtual UPS with your variables next time so I catch simple mistakes like this! I think the extra decimal places fix may be best applied at the gauge its self. I'm tempted to wrap that work into #136, especially since they too are missing the battery.voltage reading.
But in the meantime, I'll work on applying the next sub-feature here which is reading directly from output.realpower. Do you feel the current reading is fairly accurate then? Your realpower last time was ~200W and the power variable was around ~300W, so I wonder if you may have just been using more power when taking this picture.

2 months ago I was able to emulate your UPS based on the variables you gave me earlier, so hopefully I catch issues in the future!
I'll look into rounding that Load calculation and implement the next step.

2 months ago Another build is up now, this time with direct reading of output.realpower as well as correcting the decimal places. Please give it a try and let me know how it goes. I'll take a look at your translation PR then have a pre-release up soon.

Thanks for your fix. It seems to be working well.
