Description

I would like the option to be able to disable 'charging' status when using INA3221, INA219, etc, to sense battery voltage and current flow.

Even better would be the option to reverse current flow direction that activates charging status. WITHOUT a custom firmware build, which I have to currently do.

Currently with the new 2.5.18 firmware version:
Negative current flow measured in channel 1 means that 'charging' status is activated.
Positive current flow measured in channel 1 means that 'charging' status is deactivated.

This is a problem for me since all my remote nodes are hardwired to show negative current flow when discharging. The main issue is that not everyone will have their nodes wired the same way, so being able to control the status would be a nice option instead of having to disassemble and rewire nodes in the field if you want to use official builds.

Makes sense to me. Negative number is the battery losing energy, positive is its gaining.
It also means when everything is "good" and working, the solar panel, the MPPT output, and the battery will all have positive current when its sunny out.
