Wiki Script, don't work "Python - Monitor Domoticz IP address"

[bjornsundberg]

Hi,

I Need to have a IP discovery script and "Python - Monitor Domoticz IP address" looks fine but it dosent work. I think urllib2 is the problem.

Any tips on how to get this to work:

I Need to have a IP discovery script and "Python - Monitor Domoticz IP address" looks fine but it dosent work. I think urllib2 is the problem.

The port number was missing from this python script and the script is written for python2. I now updated the wiki script to include the port number and also added a version that works with python3. (converted from the original using the 2to3 tool (sudo apt install 2to3) )

I tested them successfully on my systems but if it still not OK for you, please include the errors when executed from the command line.

IMHO that script has no purpose.
you publish the new ip address to a sensor you can no longer read, since the ip address has changed.
much better would be an email with the new ip address.
better use a portscanner and scan your network for open port 8080, or whatever port you use. NMAP is a good portscanner

just my S.02

Hi, Sorry for not explaining. I will use it to publish to a mqtt broker that recieves the IP adress. Do you know how to fix the script?

I fixed the script on the wiki page.

Hi,

Just tested with python3 script but this is the results:

pi@raspberrypi:~/domoticz/scripts/python $ python ip_address.py
Traceback (most recent call last):
File "ip_address.py", line 8, in <module>
import urllib.request, urllib.error, urllib.parse
ImportError: No module named request

Just tested with python3 script but this is the results:
pi@raspberrypi:~/domoticz/scripts/python $ python ip_address.py

did you try

Code: Select all

python3 ip_address.py

after removing the first (shebang) line of the scripts ?

what do you see when entering

Code: Select all

python --version
python3 --version
python2 --version

Seems to be an authorisation issue. (are you authorized to access domoticz without password?)

Make sure that in the Security section in the settings (Setup > Settings > System > Local Networks (no username/password) you allow 127.0.0.1 (and / or ::1 when using IPv6 ) to not need a password.
