python script to control a Brennenstuhl Premium-Web-Line V3

brennenstuhl_control.py

# Brennenstuhl Premium-Web-Line V3 is a socket strip with an embedded web server. 
# It can be switched via a web interface or using http get requests. The latter is a bit under-documented, 
# so here's what i found out:
# The built-in server accepts only authenticated http get requests (using digest auth).
# each command has its own url, like so: http://{IP-OF-THE-SOCKETSTRIP}/cgi/{commandname}?params
# full list can be found in a PDF called "Premium-Web-Line V3 CGI specification.pdf" which is included in the download package of the official software:

# here's an example on how to toggle one of the two relais (nr. 0)
# modified a general digest auth example from stackoverflow: https://stackoverflow.com/questions/23254013/http-digest-basic-auth-with-python-requests-module


import logging
import requests
from requests.auth import HTTPDigestAuth

try:
    import httplib
except ImportError:
    import http.client as httplib

httplib.HTTPConnection.debuglevel = 1

# you need to initialize logging, 
# otherwise you will not see anything from requests
logging.basicConfig(level=logging.DEBUG) 

# make request
url = 'http://10.0.1.118/cgi/toggleRelay?Rel=0' #Rel=1 would toggle the other relay
# user / password is factory set to admin/admin - you better change this quick.
r = requests.get(url, auth=HTTPDigestAuth('admin', 'admin'),
                 timeout=10)
print(r.status_code)

print(r.headers)

Great! Thankyou! I always tried the same via curl but that does not work. Foreverboy searching a one-liner:

python3 -c "import requests; r = requests.get('http://192.168.0.12/cgi/toggleRelay?Rel=0', auth=requests.auth.HTTPDigestAuth('admin', 'admin'), timeout=10); print(r.status_code)"

Thank you, very useful 👍
i also tried curl but never got the parameters right..
then python.
I would really like to how it's done though...

Yeah, curl can also do a getand a digest authentication.. But I always get a permission denied" error. Maybe I should do a Wireshark debug session to understand the difference between the python and the curl command. Would be a nice learning.

same here – if you find the time to do that, i'd be curious to hear why it fails.
