Show bluetooth device battery level in openbox

i have been searching around forums but cannot find workaround on showing bluetooth device battery level
i myself is not a tech wizard and dont know much about bluetooth scripting
is there any way i check bluetooth device battery level ? bonus if it can show in like an applet in taskbar

i have tried this Read battery status bluetooth headset linux - Stack Overflow but come to no avail as there is no solution and no output from list-attributes

I don’t know it there is any.

You will have to experiment with different power management apps.
