This can be merged after the CI checks are done..

As a side-note, have you seen the other two new states seen in the backend lib? The codes 100 and 101 (charging complete and device offline) added with rytilahti/python-miio#525 .

[benleb]

ah thanks! added them also

[rytilahti]

See the inline commentary on the new extra states.

I suggest to add the two new states as xiaomi specific state attributes for now.

[benleb]

I suggest we keep this PR for the STATE_CLEANING and forget about the other two ;)

[rytilahti]

Sounds good to me, let's get this merged. Those two extra states sound odd anyway (esp. device offline). Maybe they are some internals used by the xiaomi cloud, maybe @syssi knows more.
