wordclock does not run on startup via crontab

[kas1kas]

wordclock does not start automatically after changing crontab:

sudo crontab -e @reboot sudo python /home/pi/rpi_wordclock/wordclock.py

Any tip? I have set console autologin as pi user no message, no error

I guess there is some bug in the wordclock software because it does work when I change

startup_message = ShowIP to text.

Below the error with the ShowIP keyword:

I don't really need the IP address to be shown on startup but if anyone wants to fix it:

Traceback (most recent call last): File "/home/pi/rpi_wordclock/wordclock.py", line 167, in word_clock.startup() File "/home/pi/rpi_wordclock/wordclock.py", line 104, in startup

  • Environment: production self.wcd.showText("IP: " + netifaces.ifaddresses(interface)[2][0]['addr'])

Thanks for reporting this. I expect that it fails because it does not have an ip address yet. This could be handled in the application, or a delayed start could be introduced in crontab. Or your solution of course.

Thanks for reporting, @kas1kas! The clock should definetly not crash, if no ip is provided.

Here we go, @kas1kas ;)
