Hello all, I was curious about the current reading. In my opinion it seems reverse what I am expecting. I feel it should read negative when discharging and positive while charging. What are your thoughts?
I can not remember if it is this way with all firmware versions or not as I am on an unreleased alpha.

the stock system controller firmware reports discharge current for the SoM when requested. i personally don’t find it confusing, but you could pretty easily modify the keyboard firmware’s remote.c:168 to make the divisor negative like so:
// just change '1000.0' to '-1000.0'
bat_amps = ((double)atoi(&response[amps_offset]))/-1000.0;
… and that will invert the output on the power status screen so it’s negative when discharging and positive when charging.
