core: freebox : Can't reconfigure freebox

The problem

Following this bug report : https://github.com/home-assistant/core/issues/38695#issuecomment-719424439 I deleted my freebox config to add it up again to test if the fix was working as expected, but I can’t make it work again.

This is what I did:

• Removed integration from the GUI
• Shutdown HA
• Removed the freebox folder in .storage
• Restarted HA
• Notified that the freebox integration was waiting to be configured
• Configured it like the previous time, confirmed/accepted the connection on the freebox panel
• Then nothing 😃

Here is what I get now when it starts or just after pairing:

2020-12-01 13:43:07 ERROR (MainThread) [homeassistant.config_entries] Error setting up entry *******.fbxos.fr for freebox
Traceback (most recent call last):
  File "/usr/src/homeassistant/homeassistant/config_entries.py", line 236, in async_setup
    result = await component.async_setup_entry(hass, self)  # type: ignore

  File "/usr/src/homeassistant/homeassistant/components/freebox/router.py", line 123, in update_sensors
    self.sensors_temperature[sensor["name"]] = sensor["value"]
KeyError: 'value'

Here is what I tried so far after encountering the issue:

• I tried to remove authorizations from the freebox OS interface, or to check all rights but to no effect.
• Connexions entrantes is configured correctly
• Gestion des accès / Applications appears correctly after configuration in HA, tried to check all rights
• Tried to remove it again, and pair it again

Environment

• Home Assistant 0.118.4 running on Docker (on Synology but doesn’t change much)
• Integration causing this issue: freebox
• Link to integration documentation on our website: https://www.home-assistant.io/integrations/freebox

Problem-relevant configuration.yaml

Done via GUI no yaml configuration related
