OpenUPS driver reports wrong output current while charging #495

Open julien23dev opened 6 years ago

julien23dev commented 6 years ago

While charging, the OpenUPS driver reports wrong ouput current as I know my load on output is near 20W (1,7A @12V): battery.capacity: 100 battery.charge: 72 battery.charge.low: 5 battery.charge.warning: 20 battery.current: 4.210 battery.mfr.date: ? battery.runtime: 3932100 battery.temperature: 40.50 battery.type: ? battery.voltage: 13.78 device.mfr: Mini-Box.Com device.model: OPEN-UPS device.serial: PBSO4-LiFePO device.type: ups driver.name: usbhid-ups driver.parameter.pollfreq: 30 driver.parameter.pollinterval: 2 driver.parameter.port: auto driver.parameter.synchronous: no driver.version: 2.7.4 driver.version.data: openUPS HID 0.4 driver.version.internal: 0.41 input.current: 4.225 input.voltage: 23.96 output.current: 1.080 output.voltage: 12.01 ups.mfr: Mini-Box.Com ups.model: OPEN-UPS ups.productid: d004 ups.serial: PBSO4-LiFePO ups.status: OL CHRG ups.vendorid: 04d8

If I unplug the power and the board switch output on battery, the output current is correct : battery.capacity: 100 battery.charge: 73 battery.charge.low: 5 battery.charge.warning: 20 battery.current: 653.640 battery.mfr.date: ? battery.runtime: 39060 battery.temperature: 38.10 battery.type: ? battery.voltage: 13.17 device.mfr: Mini-Box.Com device.model: OPEN-UPS device.serial: PBSO4-LiFePO device.type: ups driver.name: usbhid-ups driver.parameter.pollfreq: 30 driver.parameter.pollinterval: 2 driver.parameter.port: auto driver.parameter.synchronous: no driver.version: 2.7.4 driver.version.data: openUPS HID 0.4 driver.version.internal: 0.41 input.current: 0.000 input.voltage: 1.21 output.current: 1.724 output.voltage: 11.98 ups.mfr: Mini-Box.Com ups.model: OPEN-UPS ups.productid: d004 ups.serial: PBSO4-LiFePO ups.status: OB DISCHRG ups.vendorid: 04d8

If I use OpenUPS monitoring software, the output power (expressed un Watts) is always correct. I suspect the nut driver should use a different scaling factor according to charging state...

I realize it is likely the problem is on the NUT side, but for reference, which version of firmware is installed on the OpenUPS?

I also feel like it's a NUT issue. I use FW 1.8. Regards.

@julien23dev Can you ask the OpenUPS vendor for the correct scale factors for FW 1.8 (and also the preferred way to parse/identify the FW version from the USB host side)? The NUT code already has two separate values for charge/discharge, and I believe those numbers trace back to a patch from Nicu Pavel (of Mini-Box.com) in 2012.
