Known Issue
This update makes AccA report absurd charging current and voltage values.
The most likely cause is AccA running the wrong commands to get the values - acca -i (what it should be running) vs acc -i (what it may actually be running).
Under investigation...

Nevermind, AccA is fine.
This is an edge case on ACC's side.

🔧
Paste and run (as root): (cd /data/adb/acc/; sed -i '/batt_info/s/b/verbose=false; b/' acca.sh; chmod 0777 acca.sh)

Playing With Termux:API - Notifications, Toasts, Text-to-speech and More


1) Install Termux, Termux:Boot and Termux:API APKs.
If you're not willing to pay for Termux add-ons, go for the F-Droid* versions of these AND Termux itself.
Since packages from distinct sources have different signatures, you can't** install the add-ons from F-Droid if Termux was obtained from Play Store and vice versa.


2) On Termux, paste and run (as a regular user):

mkfifo ~/acc-fifo; mkdir -p ~/.termux/boot; pkg install termux-api


3) Write your termux-api script that gets its input from ~/acc-fifo. Place the file in ~/.termux/boot/.
Example (text-to-speech):

#!/data/data/com.termux/files/usr/bin/sh
# This file is called sore-throat.
# It talks too much.
while true; do cat ~/acc-fifo; done | termux-tts-speak


4) Open Termux:Boot to run the script and enable auto-start.

4.1) Exclude Termux:Boot from power saving and/or battery optimization lists.


5) ACC has the following:

auto_shutdown_alert_cmd (asac)
calibration_alert_cmd (cac)
charg_disabled_notif_cmd (cdnc)
charg_enabled_notif_cmd (cenc)
error_alert_cmd (eac)

As the names suggest, these properties dictate commands acc/d/s should run at each event.
The default command is "vibrate <number of vibrations> <interval (seconds)>"

Let's assume you want the phone to say "Warning! Battery is low. System will shutdown soon."
To set that up...

Write a script that communicates with that from step 3:

# This file is called warning-script.
# It's cool af!
! pgrep -f termux-tts-speak || echo "Warning! Battery is low. System will shutdown soon." > /data/data/com.termux/files/home/acc-fifo

Run acc -s auto_shutdown_alert_cmd=". /path/to/warning-script"

Potential Kernel Commit for Custom Charging Voltage Control Support - ANY DEVICE

I'm looking for a dev who's willing to compile for me a modified LOS 14.1 Moto G4 Play (harpia) kernel for testing that possibility.

Interested, pm me @vr25xda .

P.S., my bandwidth is currently too limited and unstable for downloading kernel sources.

A new stable release is up.
