I think the firmware is broken as it didn't apply correction factor/offset to get volts in the HID diescriptors.
I haven't scanned the protocol - but *I think* in the HID report descriptors contains fields for measured value of the battery voltage and the physical unit (V, mV) that describes the value. Unit can be a physical unit but also some undimensioned value (that may need correction factor and offset) I wonder is the cyberpower really outputting volts wrong or does it report an undimensioned value which in the upsc gets interpreted as volts although it is not true volt measure report Best regards, Davor On 4/2/08, Arjen de Korte <[EMAIL PROTECTED]> wrote: > > I have cyberpower value 800E connected via usb. > > In the status battery voltage is too high 20V - 21V > > while measurement at the battery terminals gives 13.6V > > This value is reported by the UPS in 'UPS.PowerSummary.Voltage' and we > display it 'as is'.
