# Bat-Alert
|
|
|
|
An application to send [D-Bus](https://www.freedesktop.org/wiki/Software/dbus/) notifications when the (Linux) host's battery runs low.
|
|
|
|
## Prerequisites
|
|
|
|
- Install `libnotify`
|
|
- Install a Notification Server to render desktop notifications
|
|
- Use [mako](https://github.com/emersion/mako) on Wayland/Sway setups
|
|
|
|
## Usage
|
|
|
|
You can run `batalert` with default setting to send the first notification when the battery falls below 15% and repeat the notification every 3%. `batalert` resets when you plug-in your charger.
|
|
|
|
### Customization
|
|
|
|
- Check the help text:
|
|
```
|
|
batalert -h
|
|
```
|
|
- Show a notification when the battery falls below 20%, repeat notification every 4% on 16%, 12%, 8% ... :
|
|
```
|
|
batalert --threshold 20 --notification-step 4
|
|
```
|
|
- Use a custom icon:
|
|
```
|
|
batalert --icon /usr/share/icons/<your-icon>.png
|
|
```
|
|
- Monitor a certain battery, e.g., `BAT2`:
|
|
```
|
|
batalert --uevent /sys/class/power_supply/BAT2/uevent
|
|
```
