Good evening folks,

So I configured NUT on a Raspberry Pi 4 both UPS are connected over USB 
however the switch from AC Power to Battery seems to be delayed on the 
NUT communication would anyone have any ideas? The Pi Reports that the 
UPS is on battery around 30 seconds later I think this delay is long. I 
have tested it on a physical computer and the detection is around 5 to 6 
seconds with the communication from the UPS to the machine. I have 
tested both USB 2 and 3 Ports but same problem

Specs of Pi

Raspberry Pi4

Debian Raspbian

32GB Sandisk SSD


Both UPS's are APC Smart 1000 non Display
