[BUG] UPS-Lite not working properly

[hexan86]

Pwnagotchi is showing only a number followed by a dash. i.e.: 63-

My steps:

1. Shorted the two pads
2. Enabled i2c
3. Followed instructions for i2cdetect
4. Tried also to use the ups_lite.py from linshuqin329

I was expecting the standard Voltage & Percentage

Environment:

• Pwnagotchi v1.5.5
• Raspberry Pi Zero W
• UPS-Lite v1.2
• PCF8523
• Waveshare v2

Additional context With the original plugin I was expecting the standard V/%, instead I ended up with an "xx-". I tried to substitute /usr/local/src/pwnagotchi/pwnagotchi/plugins/default/ups_lite.py with another one, but I still have "xx-". I am unable to find what is putting at screen this result.

I'm having the same problem. My reddit post The UPS-Lite plugin in Pwnagotchi is for v1.1 if i not mistaken.

Yours is indicating the battery value like increasing, instead of discharging?

it increases to how much the battery has been charged. After that, it will display "xx-" while the battery is discharge.

[hexan86]

Have you shorted the pads behind? I did and now it goes down (66-, 65-, 64-,...), But still with some problems...like I've fully charged it, but starts from 73 and not from 100.

In this video the percentage is working and the ups is v1.2 https://www.youtube.com/watch?v=129jZ4tDcbA

Yes. I shorted the 2 pads behind. I'm having the same problem! No matter how long I charge, it will start from 73. And it will decrease with "xx-"

I also have the same issue, can you do sudo i2cdump -y 1 0x32 and sudo i2cdump -y 1 0x36

from your dump, it should be good. it shows all required data for ups-lite.py to function. did you still having issue? because mine look like this, I suspect that I got a defected product

pi@pwnagotchi:~ $ sudo i2cdump -y 1 0x32

I've noticed that mine works better if I proceed in this way: Power on the ups-lite, connect the charging cable, wait 'til it reaches 100%, turn off the ups-lite. Now, if I turn it on again, it goes his way from 100 to 1 without issues, but if I turn it off midway and put it in charge, it scrambles again the charge level.
