So, to confirm, the NUT footer is indeed using a calculation, but NUT statistics can't use a calculation at this time. Is that correct?

I think my problem is that ups.realpower is not provided via the UPS driver. My confusion is, if this isn't present in the driver, how is it showing up in the NUT Footer? Is that number calculated? If so, is it possible to do the same calculation in the statistics overrides? root@Tower:/boot/config/plugins/nut-dw/ups# upsc ups battery.charge: 100 battery.charge.low: 10 battery.charge.warning: 20 battery.mfr.date: CPS battery.runtime: 2043 battery.runtime.low: 300 battery.status: 100% battery.type: PbAcid battery.voltage: 13.8 battery.voltage.nominal: 12 device.mfr: CPS device.model: ST Series device.type: ups driver.debug: 0 driver.flag.allow_killpower: 0 driver.name: usbhid-ups driver.parameter.interrupt_pipe_no_events_tolerance: -1 driver.parameter.pollfreq: 12 driver.parameter.pollinterval: 2 driver.parameter.port: auto driver.parameter.synchronous: auto driver.state: quiet driver.version: 2.8.3 driver.version.data: CyberPower HID 0.83 driver.version.internal: 0.62 driver.version.usb: libusb-1.0.28 (API: 0x0100010A) input.transfer.high: 140 input.transfer.low: 96 input.voltage: 122.0 input.voltage.nominal: 0 output.voltage: 122.0 ups.beeper.status: enabled ups.delay.shutdown: 60 ups.delay.start: 120 ups.firmware: BF02105B2 ups.load: 20 ups.mfr: CPS ups.model: ST Series ups.productid: 0501 ups.realpower.nominal: 375 ups.status: OL ups.test.result: Done and passed ups.timer.shutdown: -60 ups.timer.start: -60 ups.vendorid: 0764

I'm having the same problem. I can see that the Power Draw is being read from the Cyberpower UPS as the Watts are show in the NUT footer, but the chart only reports "Waiting for Data...". Does anyone know how to get the Power Draw chart to update based on the draw reported from the UPS?

Great call out. This works perfectly and takes less than 5 seconds.
