Hello,
I installed Hass.io on a Raspberry Pi Model B+ v1.2.
The installation is successful: I can enter the home assistant main page (on port 8123).
Following the tutorial, I installed the Configurator add-on.
The problem is that when I try to start the Configurator add-on, it seems to start since no error is showns in the “Log” panel, but if I click on the “OPEN WEB UI” link, a new tab opens (on port 3218) but the browser (Google Chrome) fails to open the page (ERR_CONNECTION_REFUSED).
If I go back to the “Log” panel, I get the following error:
Traceback (most recent call last):
File "/configurator.py", line 10, in <module>

import functools as _functools

from collections import namedtuple
ImportError: cannot import name 'namedtuple'
I googled to find a solution, it seemd to be a python issue, but I did not find any solution to fix the problem and let me access the Configurator WEB UI.
