As I read into what Captn Avenger noted, it may be that it doesn’t work when run the first time but works fine thereafter. If you’d like to test this, do:
sudo python ospi.pyUse your web browser to connect and see if the Options page is there or not. Be sure to force the browser to reload pages, in Chrome, and I think most browser, do this by holding down the Shift key then click on the refresh button/icon/whatever.
If the Options page is blank, stop the sprinkler program by typing Ctrl-C which should dump you back to the command line.
Now run the sprinkler program again by using the same command as above. Tip: press the up arrow to access previous commands, then press enter when you see the one you want.
