dyson.py unable to handle "OFF" humidity state

[TheBrickster]

Home Assistant release (hass --version):
0.49.0

Python release (python3 --version):
Python 3.5.2

Component/platform:
Dyson

Description of problem:
dyson.py script is expecting a numeric value for the "humidity sensor" reading, however when provided with "OFF" the script crashes and HASS does not load.

Expected:
It is expected that the dyson.py script can cope with the status provided by the humidity sensor and allow HASS to load without issue.

Problem-relevant configuration.yaml entries and steps to reproduce:

dyson:
  username: XXX
  password: XXX
  language: GB
  devices:
    - device_id: PE9-UK-XXXXXXXX
      device_ip: 192.168.86.32

Discussed on https://community.home-assistant.io/t/dyson-link-action-and-sensor/10145/65

The fix was to edit the file /components/dyson.py

and update the line

REQUIREMENTS = ['libpurecoollink==0.2.0']

With

REQUIREMENTS = ['libpurecoollink==0.3.0']

Based on there being a fix that you've identified, are you comfortable making the change and submitting a PR?

[CharlesBlonde]

I confirm the issue and I'll submit a PR soon.

One possible other workaround is to enable continuous monitoringon the Dyson devices (not tested yet, can not confirm).

Hi Charles, I am unable to comment on the HA forum - apparently a 3 post limit for newbies...

I've turned on continuous monitoring, and after a short while the dashboard reflected that the humidity detected is 49% (the same as reported in my app).

Also, to check that it was a viable workaround, I left continuous monitoring switched on, and reverted the setting back to

REQUIREMENTS = ['libpurecoollink==0.2.0']

I was able to start HASS without any issues.

However, for my purposes, I will switch it back to 0.3.0 so I don't need to leave continuous monitoring switched on.

Sorry for the delay, I just submit a PR to fix this issue if devices are configured with standby monitoring disable.
