logbook is full of warnings

Hello,

I use the "Home Assistant Operating System" installation. I did the integration manually and before that I turned on I2C on the RASPI.
The ups is recognized and I can see online status and charge status. But after some time many entries appear in the logbook:

Also, the battery only charges to 90%

I have no more idea that I can do

Also, the battery only charges to 90%

A current battery capacity algorithm is based on bus voltage which uses this formula:

 percent = (bus_voltage - 6) / 2.4 * 100

so 6V - 0% and 8.4V - 100%

I've used this code from the official SDK.

I have the same issue with the batteries after two years of usage. Maybe it's battery degradation that causes a decrease in voltage as the battery loses capacity over time.

I've added max_percent property to do such calibration.

Thanks for the feedback,
the batteries are brand new, but the charge indicator is not a problem for me. More important for me is why the many entries occur in the LOG

In the last update, I made the online status more stable by reducing sensitivity.

You can now set max percent in the configuration:

sensor:
  - platform: waveshare_ups_hat
    max_soc: 91   

So if 91 is max percent UPS will show 100%.
