CLI tool which notifies you when laptop battery reaches a threshold.

Why should you use rusty-battery?

If you aren't able to set start/stop charge threshold (for example via TLP) but would still like to make sure that your battery won't exceed your preferred threshold. rusty-battery can let you know when your battery reached the threshold by showing a desktop notification and optionally pinging your KDE Connect devices.

Features

notify

Notify whenever battery percentage exceeds the given threshold

Usage: rusty-battery notify [OPTIONS]

Options:

-t, --threshold <THRESHOLD>
        Battery charge threshold

        Whenever the chosen battery device reaches this charge threshold and will be charging, notifications will be sent, alerting that the charger should be unplugged.

        [minimum: 0] [maximum: 100]

        [default: 80]

-v, --verbose...
        More output per occurrence

-m, --model <MODEL>
        Battery model name

        If this value is omitted and only battery device is found for the current device, that one will be used.

        Otherwise, please use the `batteries` subcommand to get a list of all battery devices to get the model of the wanted battery device which should be monitored.

-q, --quiet...
        Less output per occurrence

    --refresh-secs <REFRESH_SECS>
        Number of seconds to wait before refreshing battery device data

        After every battery device refresh, its data will be checked. Notifications will be sent everytime they should be, based on the new refreshed battery device data.

        [default: 30]

    --summary <SUMMARY>
        Notification summary

        Supported variables: THRESHOLD, CHARGE_STATE, MODEL, REFRESH_SECS

        Reference these variables in your summary like shell environment variables with the '$' prefix.

        [default: "Charge limit warning"]

    --body <BODY>
        Notification body

        Supported variables: THRESHOLD, CHARGE_STATE, MODEL, REFRESH_SECS

        Reference these variables in your body like shell environment variables with the '$' prefix.

        [default: "Battery percentage reached the $THRESHOLD% threshold, please unplug your charger"]

    --kde-connect [<KDE_CONNECT_NAMES>...]
        KDE Connect device names

        If this value is not present, KDE Connect will not be used.

        If this value is empty, all of the KDE Connect devices will be pinged.

    --disable-desktop
        Disable desktop notifications

        Specify this flag if you don't want desktop notifications to be shown whenever the chosen battery percentage exceeds the given threshold.
