Not a requirement for this PR, but this integration should get updated to the new fan entity model at some point https://developers.home-assistant.io/docs/core/entity/fan

[starkillerOG]

@bdraco thanks for the input!
However I am currently only converting all Miio platforms to Config Flow, so the fan entity model is indeed out of scope for this PR.
All services accross the Miio integration schould also be updated to Entity services at some point.

@MartinHjelmare Could you also revieuw this Xiaomi Miio Fan config flow (since you did the other Miio config flows)?

[bieniu]

Shouldn't humidifiers use a humidifier platform instead of a fan platform?

[syssi]

@bieniu You are totally right but this isn't the scope of this PR.
