so im following the instructions on the interval_program example on github and I cant get the opensprinkler software to fire up on boot..
```
    host=$(hostname -I | sed 's/ *$//g')

port=:80

cd /var/www/opensprinkler/

python ospi.py $host$port
```
I have set /etc/rc.local to 755, and /var/www/opensprinkler is root:root owned and 777 chmodded. Yet i cant get it to execute the python script on boot

any ideas?

Have you tried to launch the code without rebooting?

I’m a bit rusted with rc.local. Did you try starting it manually and print the error log here?

Have you tried it as a one liner in rc.local?
```
host=$(hostname -I | sed 's/ *$//g');port=:80;cd /var/www/opensprinkler/;python ospi.py $host$port
```
Also try setting the full path to ‘python’ like ‘/usr/local/bin/python’ <- check that path on your device. I don't have an OSPI!

BTW: Why not skip the ‘cd …’ part and use full paths all the way to minimize any errors?
```
host=$(hostname -I | sed 's/ *$//g');port=:80;///python /var/www/opensprinkler/ospi.py $host$port
```

First of all, I assume your ospi.py is copied to /var/www/opensprinkler folder, otherwise it obviously won’t find the .py file to run. Second, instead of using the $host and $port variables, I believe you can just do ‘python ospi.py 80’ to start up the program on http port 80. Note that you don’t have to put the files in /var/www/opensprinkler folder — when the python server starts, it will map the http link to whatever folder it’s running the ospi.py program from. For example, you can put it in /home/yourusername/OSPI and run the python program from there.

I took your advice and changed the rc.local to be like so:
```
cd /var/www/opensprinkler

/usr/bin/python ospi.py 80

exit 0
```
i then issued:
```
sudo reboot
```
Once the pi rebooted i ran:
```
ps -ef | grep python
```
which returned:
```
pi@opensprinkler ~ $ ps -ef | grep python

root      2130  2128  0 01:56 ?        00:00:00 sudo /usr/bin/python ospi.py 80

root      2131  2130  1 01:56 ?        00:00:01 /usr/bin/python ospi.py 80

pi        2310  2292  0 01:58 pts/0    00:00:00 grep --color=auto python
```
seems to be working now. I believe it was the absolute path to python that made it work

I’ll fork the Github repo examples for the interval_program and update it appropriately.
Thanks
