I am getting the same error:
/home/pi/demo/gcalendar/ospi_gc.py:120: RuntimeWarning: This channel is already in use, continuing anyway. Use GPIO.setwarnings(False) to disable warnings.
GPIO.setup(pin_sr_lat, GPIO.OUT)
I am not 100% sure but it might have something to do with running this script while the sprinklers_pi program is running?
So I have came to the conclusion that the gcalendar addon needs to be combined with the sprinklers_pi/mobile app. I love the interface and ease of the mobile app but when it comes to scheduling I find it more of a pain to add and change stuff. Possibly an option with a checkbox for bypassing the program mode with the google calendar_id and if enabled the app can do an API call to get the schedules. Since all the code is there it would be easy to do another API call to save the information to google….Just a thought!
I want to see if I can get a reply here before I attempt to crack open the sprinklers_pi/mobile app.
Thanks fellas and thanks for such a kick ass/inexpensive house MOD. Took me an hour to set up from start to finish (download, burn, plug in, turn on, hook up, configure, change password, forward router) and I was all done setting up the coolest sprinkler system on the block.
