Simple driver for reading data from Phoenixtec ("Amazon Basics") UPSes written in c
|
|
|
|
## Why?
|
|
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](https://github.com/DrMaxNix/phoenix-upshid/blob/main/nut-reverseengineering.md) 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"!

|
|
Bus 001 Device 005: ID 06da:ffff Phoenixtec Power Co., Ltd
|
|
...
|
|
```
|
|
|
|
Print device data of device `06da:ffff` (and try usb reset):
