Sending data to COSM program stopping

[egutting]

Hello, I was able get the RPi to read the temp and send it in, but after about 2 hours the python program seems to stop. Is this normal?
Thanks!

I was doing something similar with this tutorial and having a similar problem. I was able to keep the script running for 24 to 30 hours before I needed to restart it.
I eventually took the "While (True)" part of the loop out of the code and set up a cron job to run every minute and execute the code. Check out this feed. Or my dashboard.

That worked great! Thanks!

Regarding "I eventually took the "While (True)" part of the loop out of the code and set up a cron job to run every minute and execute the code." Can you say a little more about setting up a cron job. Here's the command that I enter from the command line which does work: "sudo /home/pi/python/oneshot-cosm-temp.py" To define the cron job I entered "crontab -e" and then put in a single line

* * * * * root home/pi/python/oneshot-cosm-temp.py

The result is - no error messages, but nothing is written to my screen nor sent to cosm. So as far as I can tell, my cron job does nothing

Any ideas?

thanks

e024576,
I am at work right now.
Once I get home, I will look over my notes and see if I can shed some light on your question.

e024576,
Sorry I didn't get back to you sooner. I got busy with a few things, then forgot all about replying...
So, here is what I can tell you:
I created a small script called Get_Temp.sh that looks like this:

Code: Select all

cd Adafruit-Raspberry-Pi-Python-Code/Adafruit_DHT_Driver
sudo ./DHT_Temp.py


DHT_Temp.py is my hacked up Python program that I discussed up above.

For my crontab setup, it looks like this:

Code: Select all

* * * * * sudo ./Get_Temp.sh


I am no Linux expert, I'm sure I have not done things they way the Linux "purists" would like to see them done.
But, I do know it works!
I hope this helps... If not, ask more questions!
Scott
