NAME

battery - This module reads battery status

DESCRIPTION

This module reads battery status from /sys/class/power_supply and uses udev to monitor for changes.

Note that it is common (and "normal") for batteries to be in the state unknown under certain conditions.

For example, some have been seen to enter the unknown state when charging and the capacity reaches ~90%. The battery then stays in unknown, rather than charging, until it has been fully charged and enters the state full.

This does not happen with all batteries, and other batteries may enter the state unknown under other conditions.

TAGS

Name Type Description
name string Battery device name
manufacturer string Name of the battery manufacturer
model string Battery model name
state string One of full, not charging, charging, discharging or unknown
capacity range capacity left, in percent
estimate string Estimated time left (to empty while discharging, or to full while charging), formatted as HH:MM.

CONFIGURATION

Name Type Req Description
name string yes Battery device name (one of the names in /sys/class/power_supply)
poll-interval int no How often, in milliseconds, to poll for capacity changes (default=60000). Set to `0` to disable polling (warning: many batteries do not support asynchronous reporting). Cannot be less than 250ms.
battery-scale int no How much to scale down the battery charge amount. Some batteries report too high resulting in bad discharge estimates. Default=1.
smoothing-secs int no How many seconds to perform smoothing over for battery discharge estimates. Default=100s.

EXAMPLES

  left:


    - battery:


        name: BAT0


        poll-interval: 30000


        content:


          string: {text: "BAT: {capacity}% {estimate}"}
