Simple driver for reading data from Phoenixtec ("Amazon Basics") UPSes written in c


A while ago I bought a UPS (Uninterruptible power supply) from Amazon Basics. I tried multiple drivers for it, but they all had their problems:

  • NUT tended to mess up the USB connection after some days to a point where you had to unplug and re-plug the USB cable of the UPS
  • UPower had a stable connection, battery percentage was updated in real-time, but the charging state was frozen, displaying fully-charged when UPS was at 5% charge or displaying charging when UPS was already at 100%
  • ..and many more that didn't work at all.

So I tried writing dirty fixes for both of those drivers, which would reset the USB connection when detecting such problem. But it wasn't as stable as I had hoped.

At the end I reverse-engineered the USB-HID protocol of the UPS and wrote my own driver for it in c, which has the reset-capability built-in. I'm not at all into c driver development, so use this at your own risk, as the license already states: "WITHOUT WARRANTY OF ANY KIND"!
