Exec binding and problems with openhab service

Hey there,

my exec binding doesn´t work.
Openhab runs under user openhab:
root@raspberrypi:/home# ps -ef|grep openhab
openhab 4006 1 0 22:55 ? 00:00:00 /bin/sh /usr/share/openhab2/runtime/karaf/bin/karaf server
openhab 4119 4006 5 22:55 ? 00:01:58 /usr/bin/java -Dopenhab.home=/usr/share/openhab2 -Dopenhab.conf=/et…

The permissions are on 777:
drwxrwxrwx 2 openhab openhab 4096 Nov 22 13:50 html
drwxrwxrwx 3 openhab openhab 4096 Nov 22 13:50 icons

Installed is openhab 2 beta 4

I have tested several variants of switches:

Switch Licht_EG_Wohnzimmer_FSD1 “Wohnzimmer Stehlampe” (gEG_Wohnzimmer) {exec=">[ON:/etc/openhab2/scripts/licht_an.sh] >[OFF:/etc/openhab2/scripts/licht_aus.sh]"}
//Switch Licht_EG_Wohnzimmer_FSD1 “Wohnzimmer Stehlampe” (gEG_Wohnzimmer) {exec=“OFF:/etc/openhab2/scripts/licht_aus.sh, ON:/etc/openhab2/scripts/licht_an.sh”}
Switch Licht_EG_Wohnzimmer_FSD2 “Wohnzimmer Kugellampe” (gEG_Wohnzimmer) {exec=“OFF:/etc/openhab2/raspberry-remote/send 10101 1 0, ON:/etc/openhab2/raspberry-remote/send 10101 1 1”}

When I switch the one with the script, the echo is done, but my light doesn´t go on or off
Script:
/etc/openhab2/raspberry-remote/send 10101 1 1
echo “licht an” >> /etc/openhab2/scripts/test.txt

When I do /etc/openhab2/raspberry-remote/send 10101 1 1 with root user, the light turns on.
I just wanted to test it with my openhab user. But now I crashed my installation:
root@raspberrypi:/etc/openhab2/scripts# su - openhab
Kein Verzeichnis, Anmeldung mit HOME=/

So I deleted openhab user and added it new:
root@raspberrypi:/etc/openhab2/scripts# useradd -m openhab

openhab@raspberrypi:~ $ /etc/openhab2/raspberry-remote/send 10101 1 1
using pin 0
wiringPiSetup: Must be root. (Did you forget sudo?)
doesn´t work, too. And wiring pi IS installed with root permissions.

Can somebody help me out?
