详细描述

Okta is the usual unit of measurement of the cloud cover. The cloud cover is correlated to the sunshine duration as the least cloudy locales are the sunniest ones while the cloudiest areas are the least sunny places.

This is a fixed size datapoint type with the length of 1 byte.

enum class QKnxCloudCover:: Scale

This enum holds the unit of measurement (Okta) used to describe the amount of cloud cover at any given location. Sky conditions are estimated in terms of how many eighths of the sky are covered in cloud, ranging from completely clear sky through to completely overcast.

常量	值	描述
`QKnxCloudCover::Scale::Cloudless`	`0x00`	Denotes a sky that is completely clear.
`QKnxCloudCover::Scale::Sunny`	`0x01`	Denotes a cloud amount of 1/8 or less, but not `Cloudless` .
`QKnxCloudCover::Scale::Sunshiny`	`0x02`	Denotes a cloud amount of 2/8 or less, but not `Sunny` .
`QKnxCloudCover::Scale::LightlyCloudy`	`0x03`	Denotes a cloud amount of 3/8 or less, but not `Sunshiny` .
`QKnxCloudCover::Scale::ScatteredClouds`	`0x04`	Denotes a cloud amount of 4/8, so the sky is half cloudy.
`QKnxCloudCover::Scale::Cloudy`	`0x05`	Denotes a cloud amount of 5/8 or more, but not `VeryCloudy` .
`QKnxCloudCover::Scale::VeryCloudy`	`0x06`	Denotes a cloud amount of 6/8 or more, but not `AlmostOvercast` .
`QKnxCloudCover::Scale::AlmostOvercast`	`0x07`	Denotes a cloud amount of 7/8 or more, but not `Overcast` .
`QKnxCloudCover::Scale::Overcast`	`0x08`	Denotes a sky with full cloud cover and no breaks.
`QKnxCloudCover::Scale::ObstructedFromView`	`0x09`	Denotes a sky obscured by fog or other meteorological phenomena.
`QKnxCloudCover::Scale::Invalid`	`0xff`	The value is invalid.
