Question about UPS software control

Anonymous user · ‎2021-06-28

I'm planning to get an APC UPS so there's a question:
I want to write a program to monitor the power status of the computer, it has to determine whether there's an AC power connected and the time left for the computer to work if it's on battery power.
There's standard Win32 API function to do so (GetSystemPowerStatus()), what i want to know is whether the UPS reports to Windows about it's power status?

I'm not sure about USB, but if it's on RS-232C, SmartUPS passively reports:
"!" when power is lost
"%" when battery is low

"j" inquiry to UPS brings back the time UPS thinks the load will run on battery
"f" brings back the UPS' estimate of battery capacity.
You'll have to set up the software to inquire the UPS every however many seconds you wish the information to be updated.
