[SOLVED] No switch button in BasicUI

@Trainer and the log when toggling the Switch?
Rebooting the RPI is a good idea, any time!

Did you follow the instructions?

If you need sudo there is almost something wrong with your permission. But if you really want it this is how it has to be made!
Did you execute a sudo command as user openhab/openhabian?

But lets try to get it done without sudo!

  1. Did you add Openhab/openhabian to the gpio group?
sudo adduser openhab gpio
  1. Did you try to execute the command within the user scope of openhab/openhabian?
sudo -u openhab /opt/rc-switch/rcswitch-pi/433Utils/RPi_utils/switchOff.sh 1

What is the result when executing this two lines?
