Custom Functions
Overview
If your product functions are not in the standard function selections, you can customize the function. Function points are abstract representations of product functions, each of which can be defined by different functional types. The current platform provides: Boolean, numeric, enum type, fault type, string type, through the transmission of these six types of functions.
Among them, the Boolean type, numerical type, enumeration type is the basic type, most of the functions can be defined by the three types of functions. Fault type specifically for fault definition, easy to failure statistics in the background. The string type and the transparent type are advanced types. They are used for more complicated functions. They are recommended only when other types can not be satisfied.
How to define function points, as described in detail below.
Function Point：That is, the abstraction of the specific smart device functions, used to describe the product function and its parameters.
Function Point ID：Function point coding, follow-up equipment and the function of cloud data transmission through the function point ID.
Function Point Name：Custom Function Name
Identifier Name：Function point code value used for the multi-language management of App display function name. Support for letters, numbers, underscores, beginning with a letter.
Data Category：
Boolean (bool): non-true or false binary variable. Such as: switch function, on / off
Value (value): suitable for linear adjustment of the type of data. Such as: temperature regulation, temperature range 20-40 ℃
Enum (enum): custom finite set value. Such as: working levels, low / mid / high
Fault (fault): dedicated to reporting and statistical failure of the function points. Support multi-fault, the data reported only
String（string）: A function point that is transmitted as a string
Transparent (raw): in binary form transparent function points. Generally do not recommend the use of the function points.Can be used when you meet some complex functions that can't be satisfied with the function points above.
Data transfer type：
Can be issued and reported: the command data can be sent to the equipment, equipment data can be reported to the cloud;
Report only: Data only supports reporting from the device;
Only issue: data can only issue from the cloud;
Detailed Functional Types
Bool Type
Applicable functions: non-true or false binary variable function. Function example: the device switch, heater child lock, electric fan swing, air purifier filter reset and other functions, can be used Boolean expression.
Value Type
Applicable functions: Suitable for linearly adjustable data types.
Function Case:
Temperature change, the temperature range of 20-40, spacing 1, the unit is ℃, it means that the product can adjust the temperature of 20-40 ℃, each change in operation 1 ℃.
For schedule function, you can reserve 1, 2, 3, ... 12 hours to switch on/off, you can set the value range: 1-12, space: 1, unit: hour.
Enumeration Type
Applicable functions: This feature has a limited set of custom values.
Function Case:
Levels,low / mid-range / high-grade;
Mode: Comfort mode, sleep mode, intelligent mode, energy-saving mode;
Color: red, blue, green, black;
Note: When editing a function point, the enumeration value supports letters, numbers, and underscores. When the Enter key is pressed, the enumeration value is automatically generated. Enumerated values are encoded starting at 0, and are transferred with hardware encoding in an enumerated value encoding. Each enumeration value is no more than 15 characters in length and supports up to 10 enumerated values.
Enumeration value Enter one for each, need to enter once, the enumeration value will confirm the generation.
Fault Type
Applicable functions: Dedicated for reporting and statistical failure of the function points. This type of function will be used for statistics.
Function Case:
Temperature sensor failure, motor failure, high temperature fault ...
Note: Faulty data format is the bitmap type, can support multiple fault definitions. The fault type function only supports data report, so the data transmission type can only choose Report Only.
Char Type
Applicable functions: Function points transmitted in the form of character strings. If the above four types of functions can not meet the definition of product functions, can be agreed through the string of data transmission.
Note: Char-type maximum length of not more than 255 bytes.
RAW Type
Applicable functions: Binary mode transparent function points. Generally do not recommend the use of the function points.Can be used when you meet some complex functions that can't be satisfied with the function points above.
Note: RAW type maximum length does not exceed 255 bytes.
It is recommended that the total number of standard function and custom function points should not exceed 40. If so, please pay attention to the stability test of the product.
