i got an Error:
Command for custom:Licht aus failed with return code 1:
STDERR: sudo: no tty present and no askpass program specified

How can i fix this?
Sry for my Bad English, i am a German User with terrible English skills...

I follwed this Tutorial:

Did you try to send the command directly in the raspberry-terminal (via ssh)?
Please post a screenshot of your command-settings.



You might need to remove requiretty from the sudoers configuration. This could possibly be:

Update: ignore this part

sudo nano /etc/sudoers

# Add the line in the header:
Defaults:pi !requiretty

I'm not sure because I've never run this plugin and this hardware that you have.

It's also possible that you just simply need to add a file:

sudo touch /etc/sudoers.d/codesend
sudo nano /etc/sudoers.d/codesend

# Here is the content:
pi ALL=(ALL) NOPASSWD: /home/pi/433Utils/RPi_utils/codesend


Good Morning!

Yes i have done this, and there it will be OK! It works without Errors...

Hello again!


You are my hero!

The Line in the sudoers File has not worked, BUT then i have created a File with

sudo nano /etc/sudoers.d/codesend

With the follwing content:
pi ALL=(ALL) NOPASSWD: /home/pi/433Utils/RPi_utils/codesend

After a Reboot the command works like a charme!
Thank you very much, for your fast help! :wink:

Have a nice Day :wink:

Best Regards
