Plex sensor not working when using username/password

[arsaboo]

Home Assistant release (hass --version): 0.60.1

Python release (python3 --version): 3.6.2

Component/platform: Plex Sensor

Description of problem: Looks like it is an upstream issue, but leaving the issue open for others until it is fixed. Also, only those using username/password will be affected. See the logs below.

Expected: Plex sensor should work :)

Config:

  - platform: plex
    name: PlexSpy
    host: 192.168.2.212
    port: 32400
    username: !secret plex_user
    password: !secret plex_password

This is an upstream issue

https://github.com/pkkid/python-plexapi/blob/master/plexapi/myplex.py

line 70: SIGNIN = 'https://my.plexapp.com/users/sign_in.xml' # get with auth

[ryanm101]

workaround is to use token to authenticate until it is fixed by the good folks over at plexapi:
https://github.com/pkkid/python-plexapi/

Filed a ticket on the plexapi lib pkkid/python-plexapi#246

[ryanm101]

Another "better" fix (until 3.0.6 is released) for the braver is find and edit the file plexapi/myplex.py

Replace SIGNIN = 'https://my.plexapp.com/users/sign_in.xml' # get with auth
with SIGNIN = 'https://plex.tv/users/sign_in.xml' # get with auth
