Hello,
is there an app to shutdown the n900 e.g. at night time automatically?
This would be very nice together with sleeper (listen to music and let the phone shutdown at a certain time)

i don't know any app which would do that.... but you could write a small script which does it for you

If you now anything about programming or at least writing (shell) scripts, you can quickly put something together by yourself.
If not, I would suggest adding [request] to your subject to get someone to do it for you.

Is there anyone else interested in such functionality?

"halt" (without the ") should shutdown the device, so get a scheduler and type the command in it, then set the device to run the command at a certain time.
E.g
Very simple and short script, place it somewhere and chmod +x it, then add it to something like Fcron.

tried it with the app "alarmed" but it doesn't seem to do anything o.O

halt requires superusers privs.

i thought so...
... and i tried some ways to run it with su privs...
... but nothing worked.

so... could you tell me how to make it using su privs without editing the sudoers file? please. ^^

would love lttle app like this...would it be possible to work off internal clock...maybe come back on after so long etc?

The widget "sleeper" stops media playback after a certain time. I use it all the time and it works pretty well. It doesn't shut the phone down, though, if that's what you really want.

there is a app called auto disconect maybe you can write to the guy see if he can implement it
