On that note, I also forgot I have a script for battery status that pops up at certain intervals.
It's running as a systemd user timer (~/.config/systemd/user/timers.target.wants).
The timer unit
Code:
[Unit]
Description=Timer to run battery-notify
[Timer]
OnActiveSec=1min
OnUnitActiveSec=1min
[Install]
WantedBy=timers.target
and service unit:
Code:
[Unit]
Description=battery-notify
[Service]
ExecStart=%h/docu/bin/check-batt
[Install]
WantedBy=default.target
And the actual script that gets called check-batt, which is very similar to what neeasade is doing but with threshold values:
Code:
#!/usr/bin/env bash
BAT_NUM='1'
STATUS_FILE=/tmp/check-bat.tmp
BATTPERC=$(cat /sys/class/power_supply/BAT${BAT_NUM}/capacity)
BATTSTATUS=$(cat /sys/class/power_supply/BAT${BAT_NUM}/status)
LAST_STATUS=''
LAST_NOTIF_LEVEL=0
NOTIF_LEVEL=0
if [ -e $STATUS_FILE ] ; then
. $STATUS_FILE
fi
save_status() {
LAST_STATUS=$BATTSTATUS
echo "LAST_STATUS=${BATTSTATUS}" > $STATUS_FILE
echo "LAST_NOTIF_LEVEL=${NOTIF_LEVEL}" >> $STATUS_FILE
}
notify() {
level=$1
msg=$2
DISPLAY=:0 /usr/bin/notify-send -t 3500 -u "$level" "POWER" "$msg"
}
# Battery status changed
if [[ "$BATTSTATUS" != "$LAST_STATUS" ]] ; then
notify "normal" "battery is now $BATTSTATUS, Capacity: $BATTPERC"
NOTIF_LEVEL=$LAST_NOTIF_LEVEL
save_status
exit
fi
if [ "$BATTSTATUS" = Discharging ] && [ "$BATTPERC" -le 10 ]; then
NOTIF_LEVEL=10
notify "critical" "battery is less than 10% - Connect charger, going to sleep in 10s"
sleep 10
BATTSTATUS=$(cat /sys/class/power_supply/BAT${BAT_NUM}/status)
if [ "$BATTSTATUS" = Discharging ]; then
notify "critical" "going to suspend now"
sleep 3
logger "Critical battery threshold, suspending"
save_status
systemctl suspend
exit
else
notify "normal" "battery is now charging, cancelling suspend"
save_status
exit
fi
fi
if [[ $BATTPERC -le 20 ]] ; then
NOTIF_LEVEL=20
notify "critical" "battery $BATTSTATUS is less than 20%"
save_status
elif [[ $BATTPERC -le 30 ]] ; then
NOTIF_LEVEL=30
if [ "$NOTIF_LEVEL" != "$LAST_NOTIF_LEVEL" ]; then
notify "normal" "battery $BATTSTATUS is at 30%"
save_status
fi
elif [[ $BATTPERC -le 50 ]] ; then
NOTIF_LEVEL=50
if [ "$NOTIF_LEVEL" != "$LAST_NOTIF_LEVEL" ] ; then
notify "low" "battery $BATTSTATUS is at 50%"
save_status
fi
elif [[ $BATTPERC -le 60 ]] ; then
NOTIF_LEVEL=60
if [ "$NOTIF_LEVEL" != "$LAST_NOTIF_LEVEL" ] ; then
notify "normal" "battery $BATTSTATUS is at 60%"
save_status
fi
fi
