CHIP Battery Auto-Shutdown

This script will check the level of a battery attached to the CHIP.

This needs to be run as root due to the shutdown command.

This script does not have a loop internal to it and should be set to a cron job (preferably root cron) at a 5 or 10 minute interval.

Installation

git clone https://github.com/xtacocorex/chip_batt_autoshutdown.git
cd chip_batt_autoshutdown
chmod +x chip_autoshutdown.sh
sudo cp ./chip_autoshutdown.sh /usr/bin/

If running the script manually, be sure to run with sudo

Cron Job Setup

Edit the root crontab

sudo crontab -e

For 5 Minute check, enter:

*/5 * * * * /usr/bin/chip_autoshutdown.sh >> /var/log/chip_batt.log 2>&1

For 10 Minute check, enter:

*/10 * * * * /usr/bin/chip_autoshutdown.sh >> /var/log/chip_batt.log 2>&1

Then do:

sudo service cron restart

To check the status of the script:

tail -f /var/log/chip_batt.log
