This will work, although my python libraries are under /usr/lib/python2.7/site-packages. However, this will not work for @Tomibeck. Attempting to use requests will return this…
TypeError: Error when calling the metaclass bases

Jython cannot use CPython extension modules written in C, so if you see a .pyc file, chances are it will not work (there is a socks.pyc). An alternative would be to use a Java library, or you could also use executeCommandLine and run anything in Jython that you can in a shell (even Python3), just as you could in the Rules DSL…
from org.slf4j import Logger, LoggerFactory
from org.eclipse.smarthome.model.script.actions.Exec import executeCommandLine
log = LoggerFactory.getLogger("org.eclipse.smarthome.model.script.Rules")
result = executeCommandLine("/bin/sh@@-c@@/usr/bin/python -c \"import requests; print(requests.get('http://localhost:8080').status_code)\"",5000)
log.info("JSR223: test requests [{}]".format(result))
This returns…

But don’t forget we are in OH! By far the easiest solution for you is to simply use one of the OH HTTP Actions.
from openhab.rules import rule
from openhab.triggers import when
from org.slf4j import Logger, LoggerFactory
from org.eclipse.smarthome.model.script.actions.HTTP import sendHttpPutRequest
log = LoggerFactory.getLogger("org.eclipse.smarthome.model.script.Rules")
url = "http://172.16.0.15/api/GBL1Hvu8d4kbK7G1iCb3BtsRQiPXFabP9RpKnjng/"
@rule("Hallway Light ON")
@when("Hallway_Motion changed to ON")
def testFunction(event):
payload = "{\n\t\"on\": true\n}\n"
sendHttpPutRequest(url, "text/html", payload)
