Hi all, I want to get the power draw from a APC USB UPS. I have managed to run apcusbd and apctest. But how to invoke these tools to get the actual power draw in Watt x Ampere?
I've found this page which describes how to read it via RS232 serial port. https://forums.anandtech.com/threads/got-an-apc-smart-ups-measure-real- power-with-it.55847/ But I dont't have such a port neither a cable. Regards Goran
