Hi all, I have adapted the battery script to Libra Colour :
- found correct path
- commented out empty lines (they generate error messages on Libra Colour, weird ?)

The result is attached.

Here is the script :

# Battery Statistics Calculator 1.1 (2024-05-25) by Aleron Ives
#
# This script calculates battery statistics for the Kobo Libra 2.
# (adapted for Libra Colour : see v_pct")
# (adapted for Libra Colour : "bd71827_bat" instead of "battery" in path)
# Check the contents of /sys/class/power_supply/ if you use a different
# model to ensure that the statistics you want to track are available.
#
# You can use NickelMenu to invoke this script like so:
# menu_item :main :Battery :cmd_output :500 :/mnt/onboard/.adds/battcalc.sh
#
# Gather the necessary statistics
#
meter=$(cat /sys/class/power_supply/bd71827_bat/capacity)
v_now=$(cat /sys/class/power_supply/bd71827_bat/voltage_now)
v_min=$(cat /sys/class/power_supply/bd71827_bat/voltage_min)
v_max=$(cat /sys/class/power_supply/bd71827_bat/voltage_max)
c_now=$(cat /sys/class/power_supply/bd71827_bat/charge_now)
c_full=$(cat /sys/class/power_supply/bd71827_bat/charge_full)
c_dfull=$(cat /sys/class/power_supply/bd71827_bat/charge_full_design)
#
# Format the statistics
#
#let v_pct=$v_max-$v_now; let v_pct/=7000 # Calculate charge percentage from V - Libra 2
let v_pct=$v_max-$v_now; let v_pct/=9000 # Calculate charge percentage from V - Libra Colour
let v_pct=100-$v_pct # "
let v_now/=1000; let v_min/=10000; let v_max/=10000 # Convert to V
let c_now/=1000; let c_full/=1000; let c_dfull/=1000 # Convert to mAh
let v_nowr=$v_now%1000; let v_now/=1000 # Simulate floating-point arithmetic
let v_minr=$v_min%100; let v_min/=100 # "
let v_maxr=$v_max%100; let v_max/=100 # "
let charge=$c_now*100/$c_full # Calculate charge percentage from mAh
let c_health=$c_full*100/$c_dfull # Calculate health percentage from mAh
#
# Display the results
#
echo Capacity: $c_now mAh / $charge% / $meter%
echo Voltage: $v_min.$v_minr V / $v_now.$v_nowr V / $v_max.$v_maxr V / $v_pct%
echo Health: $c_full mAh / $c_dfull mAh / $c_health%

Thanks, that worked.

Has anyone already tried NickelMenu on the tolino shine 5? Since the firmware v5 no longer recognizes KoboRoot.tgz, is renaming enough? Or should one keep one's hands off it at the moment?

It needs a different build for qt6... it won't even load if you try it.

Right, QT6... I was (also) afraid of that. Thanks for clarifying this.

I know I'm late to the party, but i found a solution to solve this issue: I've added a chain_always command after the dark mode toggle that runs a shell script:

menu_item : reader : Toggle Dark Mode : nickel_setting : toggle : dark_mode
chain_always : cmd_spawn : quiet : exec /mnt/onboard/.adds/misc/DarkModeHelper.sh

And here's the script:

#!/bin/sh

KOBO_CONF="/mnt/onboard/.kobo/Kobo/Kobo eReader.conf"

if grep '^DarkMode=true' "$KOBO_CONF"; then
ioctl /dev/ntx_io 241 -v 1
sed 's/^FrontLightLevel=.*/FrontLightLevel=1/g' <"$KOBO_CONF" >"$KOBO_CONF".tmp && mv "$KOBO_CONF".tmp "$KOBO_CONF"

elif grep '^DarkMode=false' "$KOBO_CONF"; then
ioctl /dev/ntx_io 241 -v 5
sed 's/^FrontLightLevel=.*/FrontLightLevel=5/g' <"$KOBO_CONF" >"$KOBO_CONF".tmp && mv "$KOBO_CONF".tmp "$KOBO_CONF"

fi

This way, every time you toggle Dark Mode, there is a check to determine whether dark mode has been turned on or off ; it then changes the level accordingly in ioctl AND in "Kobo eReader.conf", so that the level changes persist across reboots.

Has the weird header flashing thing been addressed? It only happens when I am running NickleMenu and then use some other feature like pulling up a definition — when that happens, I get flashing in the clock or page number area when changing. It goes away when I move back to the library and reopen the book.

Maybe you can see this thread, the update of Nickelclock to new Kobo devices:

Just curious as to whether anyone has modified the battcalc.sh script for other Kobo ereaders? As far as I can tell, the Clara HD and Sage only supply two of the values so not that informative.

Yes, when I originally released it, I was told that sysfs doesn't report all the statistics on every model, so the script isn't compatible with every Kobo.

I took a quick look at it... That would also mean extensive adjustments to NickelTC, right?

Yes, as Kobo gave their rootfs a massive overhaul and update for FW v5. It appears to be based on Yocto FWIW. The trick will be to try and have NickelTC sysroot match the new FW as close as possible.

Ever take too many screenshots and want a way to batch delete them? I run into this problem often, so I decided to call a script from NM instead of manually deleting the screenshots one by one on my Kobo or using FTP/Telnet to delete the files remotely.

menu_item:main:Kill Screenshots:cmd_spawn:/mnt/onboard/.adds/scripts/cleanup.sh chain_always:nickel_misc:rescan_books_full

My script has the following line:

rm /mnt/onboard/screen_*.png

Fairly simple, but I'm immensely pleased with it since it’ll save me time. Are there any Kobo specific problems I should look out for when calling scripts through NM?

And on an unrelated note, is there a way to create a submenu in NM?

As far as I can tell, Kobo's battery meter has significant drift based on your charging habits. If you try to follow the guidance of keeping the battery between 25 - 75%, the meter starts to think that 75% charged is 100% charged, because it never goes above that point. I now have a > 20% disparity between what the battery icon reports and what the voltage indicates about the charge level. I'll try doing a full charge next time to see if I can get them to line up again.
