pyg90alarm.cloud.const

Constants used in the G90 cloud protocol implementation.

This module defines the main enumerations for direction and command types used in the cloud protocol communication with G90 alarm systems.

enum pyg90alarm.cloud.const.G90CloudDirection(value)

Bases: IntEnum

Defines the direction of G90 cloud protocol messages.

These values indicate whether messages are flowing from the cloud to the device, from the device to the cloud, or are part of discovery processes.

Member Type:: int

Valid values are as follows:

UNSPECIFIED = <G90CloudDirection.UNSPECIFIED: 0>

CLOUD = <G90CloudDirection.CLOUD: 32>

DEVICE = <G90CloudDirection.DEVICE: 16>

DEVICE_DISCOVERY = <G90CloudDirection.DEVICE_DISCOVERY: 48>

CLOUD_DISCOVERY = <G90CloudDirection.CLOUD_DISCOVERY: 208>

The Enum and its members also have the following methods:

conjugate(): Returns self, the complex conjugate of any int.

bit_length()

Number of bits necessary to represent self in binary.

>>> bin(37)
'0b100101'
>>> (37).bit_length()
6

bit_count()

Number of ones in the binary representation of the absolute value of self.

Also known as the population count.

>>> bin(13)
'0b1101'
>>> (13).bit_count()
3

to_bytes(length=1, byteorder='big', *, signed=False)

Return an array of bytes representing an integer.

length: Length of bytes object to use. An OverflowError is raised if the integer is not representable with the given number of bytes. Default is length 1.
byteorder: The byte order used to represent the integer. If byteorder is ‘big’, the most significant byte is at the beginning of the byte array. If byteorder is ‘little’, the most significant byte is at the end of the byte array. To request the native byte order of the host system, use sys.byteorder as the byte order value. Default is to use ‘big’.
signed: Determines whether two’s complement is used to represent the integer. If signed is False and a negative integer is given, an OverflowError is raised.

classmethod from_bytes(bytes, byteorder='big', *, signed=False)

Return the integer represented by the given array of bytes.

bytes: Holds the array of bytes to convert. The argument must either support the buffer protocol or be an iterable object producing bytes. Bytes and bytearray are examples of built-in objects that support the buffer protocol.
byteorder: The byte order used to represent the integer. If byteorder is ‘big’, the most significant byte is at the beginning of the byte array. If byteorder is ‘little’, the most significant byte is at the end of the byte array. To request the native byte order of the host system, use sys.byteorder as the byte order value. Default is to use ‘big’.
signed: Indicates whether two’s complement is used to represent the integer.

as_integer_ratio()

Return a pair of integers, whose ratio is equal to the original int.

The ratio is in lowest terms and has a positive denominator.

>>> (10).as_integer_ratio()
(10, 1)
>>> (-10).as_integer_ratio()
(-10, 1)
>>> (0).as_integer_ratio()
(0, 1)

is_integer(): Returns True. Exists for duck type compatibility with float.is_integer.

real: the real part of a complex number

imag: the imaginary part of a complex number

numerator: the numerator of a rational number in lowest terms

denominator: the denominator of a rational number in lowest terms
