Hello,

The N/A is displayed when information for retrieving or calculating the stats is not available. This is expected behavior.

The missing values are calculated as per below and I can see that they are not available from yours.

Load: ups.load.
Output: ups.load / 100 * ups.realpower.nominal
Test: ups.test.result

Yours:
Outout could be calculated as output.current * output.voltage
load and test is not available.
battery.mfr.date: OPEN --> suggest you to overwrite this in you config (to remember when to replace). See example below:

Edit "/etc/nut/ups.conf" and add overwrites

[ups]
    driver = usbhid-ups
    port = auto
    vendorid = 051D
    productid = 0002
    desc = "APC Back-UPS BX500MI"
#    ignorelb

    # Override the default low battery percentage threshold (e.g., 40%)
    override.battery.charge.low = 50

    # Optional: override the runtime low threshold in seconds (e.g., 600 = 10 minutes)
    override.battery.runtime.low = 600
    override.battery.mfr.date = 2025/09/05

What would be your expected behavior?

@pear235 did you perform a ctrl+f5 refresh of the page? please provide screenshot to verify it is the same fields

[pear235]

I did do the ctrl+r, yea.

Not sure if this is the screenshot you wanted, if not, pls let me know :

Thanks both, @pear235 @nedomika. I will have a look. I have converted yours into a different issue as the original is different. #141

Hello,

The N/A is displayed when information for retrieving or calculating the stats is not available. This is expected behavior.

The missing values are calculated as per below and I can see that they are not available from yours.

Load: ups.load. Output: ups.load / 100 * ups.realpower.nominal Test: ups.test.result

Yours: Outout could be calculated as output.current * output.voltage load and test is not available. battery.mfr.date: OPEN --> suggest you to overwrite this in you config (to remember when to replace). See example below:

Edit "/etc/nut/ups.conf" and add overwrites

[ups]
    driver = usbhid-ups
    port = auto
    vendorid = 051D
    productid = 0002
    desc = "APC Back-UPS BX500MI"
#    ignorelb

    # Override the default low battery percentage threshold (e.g., 40%)
    override.battery.charge.low = 50

    # Optional: override the runtime low threshold in seconds (e.g., 600 = 10 minutes)
    override.battery.runtime.low = 600
    override.battery.mfr.date = 2025/09/05

What would be your expected behavior?
