Fritz!Box device tracker fails to install fritzconnection

After adding the device tracker, this happens upon starting hass:

INFO:homeassistant.loader:Loaded device_tracker.fritz from homeassistant.components.device_tracker.fritz
INFO:homeassistant.util.package:Attempting install of fritzconnection==0.4.6
Command "/usr/bin/python3 -u -c "import setuptools, tokenize;__file__='/tmp/pip-build-a75y6hpj/lxml/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-symu1gz8-record/install-record.txt --single-version-externally-managed --compile --home=/tmp/tmpjomu9sru" failed with error code 1 in /tmp/pip-build-a75y6hpj/lxml
ERROR:homeassistant.bootstrap:Not initializing device_tracker.fritz because could not install dependency fritzconnection==0.4.6

It "hangs" for more than a minute after Attempting install of fritzconnection==0.4.6, I suppose because trying to compile lxml takes a while. I'm running a headless Ubuntu server with 14.04.1 on it, python3-lxml is installed, so I'm not sure why it's even trying to compile that.

Installing fritzconnection manually (sudo pip3 install fritzconnection) works fine and installs 0.4.6 of it. Running hass afterwards results in this error:

INFO:homeassistant.loader:Loaded device_tracker.fritz from homeassistant.components.device_tracker.fritz

If there is any other information I need to provide please let me know. :)

This is an issue with the fritzconnection library not being updated for python3. See fix here. You can apply these changes yourself like that:
sudo nano /usr/local/lib/python3.4/dist-packages/fritzconnection/__init__.py

# -*- coding: utf-8 -*-

from .fritzconnection import (
    FritzConnection,
    FritzInspection,
    print_servicenames,
    print_api,
)
from .fritzhosts import (
    FritzHosts,
    print_hosts,
)
from .fritzstatus import (
    FritzStatus,
    print_status,
)

Unfortunately then you'll encounter the next error, but I gave up and going to try nmap now.

Hey I was the one to start the fritzboxdevice scanner. What is the error you encounter after adding the fix you show?

I made a fork of fritzconnection with the fix you showed. It can be found here. If you install from this repo, it should work.

git clone git@github.com:deisi/fritzconnection.git
cd fritzconnection
sudo python3 setup.py install

I remember to add this for to requirements of HA, but there have been some changes to the way HA handles requirements. Maybe during this something went wrong.

@deisi I Have applied the fixes but now i'm getting the next error?

[matthewcky2k]

I would Attempt myself but don't have the knowledge to fix it unfortunately...

[deisi]

can you show me the line of your homeassistant.config file you use to set up the device scanner.

[matthewcky2k]

yep

device_tracker:
  platform: fritz
  host: 192.168.0.254
  track_new_devices: yes
  interval_seconds: 12
  consider_home: 180

[deisi]

Okay I need to check this from home. I can tell you this evening. Did the intendations after the device_tracker: got lost in copy paste or dont you need them?

[matthewcky2k]

yeah the indentations are there in the config file

[deisi]

okay, I think I found the issue. Its due to a missing password. So try adding the password of the fritzbox with:

device_tracker:
  - platform: fritz
    host: 192.168.0.254
    password: password

After this the Key Error: Host was gone for me. Plz report if it helps.

PS:
I'm a bit confused by this error. I know it was possible to read the fritz_box.get_hosts_info() without a valid password. This might have changed from FritzOS 5 to 6.

So the import error at the beginning is because the pip version ist still not updated to contain the fix of this issue
It is likely that this will be changed in the future but I dont know when. In the mean time I think we should keep using my fork from here
The problem is, I dont know how to tell the new REQUIREMENTS variable to use the forked version.

[MartinHjelmare]

Hi!

You can use a pip string like this, to install directly from github:

REQUIREMENTS = ['https://github.com/deisi/fritzconnection/archive/b5c14515e1c8e2652b06b6316a7f3913df942841.zip#fritzconnection==0.4.6']

The hash in the string is the hash of the commit you want to use. Notice the version spec at the end. You'll need to update the version of the package whenever you want homeassistant to use another commit or version, so that pip --upgrade will work.

[deisi]

Okay, I make a PR with it. Thanks for the information.

[matthewcky2k]

@deisi working fine now thanks
