I'm using NUT add-on and integration in Home assistant. My UPS is APC BX1200.
The integration data is delayed and doesn't update after a certain point. In this situation, the charge level is stuck at 99% while I unplugged the USB and attached the PC with Power Chute personal edition and got it as 100%. Then reconnecting is back to RPi it shows 100%.Turn off the input to UPS so it dropped to 95-96% and after a while it again stuck at 99% showing charging as not 100% despite it being 100% (confirmed from Power Chute) but the integration doesn't pick it up. Also any changes are displayed with a delay of 1-2 mins.

Not sure why it reports up to 99% fine and not after that. Yesterday it got stuck at 95% then did the same process of connecting to Power Chute and back.

The Add-on always have log entries of can't write to PID fopen issues so not sure if that is the root cause or not as others have the same PID fopen error but have not reported this data stale issue.
I raised this issue with HA home-assistant/core#125723
and after investigation advised the issue is NUT package and should raise it in here.
