traits/brightness_sensor.proto

AmbientBrightness

AmbientBrightness records the light level measured by a device.

Field	Type	Label	Description
brightness_lux	float		Brightness measured in LUX

AmbientBrightnessSupport

AmbientBrightnessSupport describes the capabilities of devices implementing this trait

Field	Type	Label	Description
resource_support	smartcore.types.ResourceSupport		How a named device supports read/pull apis
brightness_lux	smartcore.types.FloatBounds		The range of values the device is capable of reporting.

DescribeAmbientBrightnessRequest

Field	Type	Label	Description
name	string		The name of the device

GetAmbientBrightnessRequest

Field	Type	Label	Description
name	string		The name for the device.
read_mask	google.protobuf.FieldMask		The state fields to fetch

PullAmbientBrightnessRequest

Field	Type	Label	Description
name	string		The name for the device.
read_mask	google.protobuf.FieldMask		The state fields to fetch
updates_only	bool		When true the device will only send changes to the resource value. The default behaviour is to send the current value immediately followed by any updates as they happen.

PullAmbientBrightnessResponse

Field	Type	Label	Description
changes	PullAmbientBrightnessResponse.Change	repeated

PullAmbientBrightnessResponse.Change

Field	Type	Label	Description
name	string		The name for the device that changed
ambient_brightness	AmbientBrightness
change_time	google.protobuf.Timestamp		when the change occurred

BrightnessSensorApi

BrightnessSensorApi reports on the measured ambient brightness for a space.

Method Name	Request Type	Response Type	Description
GetAmbientBrightness	GetAmbientBrightnessRequest	AmbientBrightness	GetAmbientBrightness returns the current brightness level as measured by the device.
PullAmbientBrightness	PullAmbientBrightnessRequest	PullAmbientBrightnessResponse stream	PullAmbientBrightness returns a stream of brightness changes as the device measures them.

BrightnessSensorInfo

Describes the capabilities of a specific named device with respect to this trait.

Method Name	Request Type	Response Type	Description
DescribeAmbientBrightness	DescribeAmbientBrightnessRequest	AmbientBrightnessSupport	Get information about how a named device implements AmbientBrightness measurements

Scalar Value Types

.proto Type	Notes	C++	Java	Python	Go	C#	PHP	Ruby
double		double	double	float	float64	double	float	Float
float		float	float	float	float32	float	float	Float
int32	Uses variable-length encoding. Inefficient for encoding negative numbers – if your field is likely to have negative values, use sint32 instead.	int32	int	int	int32	int	integer	Bignum or Fixnum (as required)
int64	Uses variable-length encoding. Inefficient for encoding negative numbers – if your field is likely to have negative values, use sint64 instead.	int64	long	int/long	int64	long	integer/string	Bignum
uint32	Uses variable-length encoding.	uint32	int	int/long	uint32	uint	integer	Bignum or Fixnum (as required)
uint64	Uses variable-length encoding.	uint64	long	int/long	uint64	ulong	integer/string	Bignum or Fixnum (as required)
sint32	Uses variable-length encoding. Signed int value. These more efficiently encode negative numbers than regular int32s.	int32	int	int	int32	int	integer	Bignum or Fixnum (as required)
sint64	Uses variable-length encoding. Signed int value. These more efficiently encode negative numbers than regular int64s.	int64	long	int/long	int64	long	integer/string	Bignum
fixed32	Always four bytes. More efficient than uint32 if values are often greater than 2^28.	uint32	int	int	uint32	uint	integer	Bignum or Fixnum (as required)
fixed64	Always eight bytes. More efficient than uint64 if values are often greater than 2^56.	uint64	long	int/long	uint64	ulong	integer/string	Bignum
sfixed32	Always four bytes.	int32	int	int	int32	int	integer	Bignum or Fixnum (as required)
sfixed64	Always eight bytes.	int64	long	int/long	int64	long	integer/string	Bignum
bool		bool	boolean	boolean	bool	bool	boolean	TrueClass/FalseClass
string	A string must always contain UTF-8 encoded or 7-bit ASCII text.	string	String	str/unicode	string	string	string	String (UTF-8)
bytes	May contain any arbitrary sequence of bytes.	string	ByteString	str	[]byte	ByteString	string	String (ASCII-8BIT)
