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!

Re: Sending data to COSM program stopping
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.

Re: Sending data to COSM program stopping
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:
DHT_Temp.py is my hacked up Python program that I discussed up above.
For my crontab setup, it looks like this:
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!
