Door control web page

One of the pages on my Coop Control web page controls the door

Below is the HTML code for the division controlling the door. The numbers at the bottom of the
screen are preset locations to aim the pan/tilt camera.

in Essence, clicking on a button calls a python program on the coop server
which returns the result to a frame on the calling page.
This is because most browsers disallow commands to servers other than the one
serving the page but do allow requests for an HTML document or image.
<a href=”http://192.168.0.150/www/open_coop.py” target=”didit”>Open Door</a>
above is the href called when the open button is pressed
Below is the python code called:
import httplib2
def index(req):
h = httplib2.Http()
resp_headers, content = h.request("http://192.168.0.150/x201on3.py", "PUT")
print(content.decode("utf-8"))
return(content.decode("utf-8"))
if __name__ == '__main__':
index('open_coop')
As you can see, it becomes even more convoluted as the python code calls another
python program to operate the relays.  That code (below) checks the state of other
relays and sets the two relays controlling the door to provide positive to the
proper side of the motor for a timed period. It also updates the database with a
timestamp of the action and the action.

Here is the Python code to open, close and stop the door. This code is run on the coop computer only.
