OpenHAB Exec Binding explained in detail on 433MHz radio transmitter example

Could you please format your post like you did here

Simple On/Off Switch with Exec-Command

Hy. I hope I find help here. I’ve been trying to use a 433 mhz module for a long time with openhab. I can use it in the shell with the following command: /home/openhabian/433Utils/RPi_utils/./codesend 13108705. And now I try desperately to integrate this command with exec binding (version 2). I hope who can help, I try to send the command as a push button. Where is my mistake? Post my composition. Thank you .items Group Licht_EG "Licht" Switch Wohnzimmer_Decke (Licht_EG) [ "Switchable" ] …

Did you try to execute the command as user openhabian as explained?
This is a crucial step to make sure openhab is able to execute the command! Make sure to take the right user openhab for self installed, openhabian for openhabian.

@Josar

sudo -u openhabian /home/openhabian/433Utils/RPi_utils/./codesend 13108705

Make sure to add openhab/openhabian to the group which is necessary to execute your commands. Most probably gpio. I don’t know what kind off 433MHz transciever you use.

Second you don’t need the shell Skript. Put your call to codesend in the thing as explained above in the tutorial. Have a closer look there.

Please post the output of

1. Executions as user openhabian from commandline.
2. After adding openhabian to the right group and successful executing 1. the output of the log from the rule.
