herbe don't update

[fostopern]

basically i have a archlinux build with herbstluftwm and herbe. i don't want to use a statusbar so i use herbe instead, basically i press F1 and open a notification that show me the battery percentage, time, date ecc. but the values doesn't update. for example: i open herbe at 12:00
and i have 100% battery if i open herbe 2 hours later the battery is still on 100% but if i reload herbstluftwm the values are updated and i can se the real percentage of battery

What's the script or command you use to invoke herbe? Specifically, with what arguments is herbe invoked?
