Function Definition

Last Updated on : 2024-06-21 04:19:48download

After a product is created, define its functions first.

You can set functions for a product, including standard functions, custom functions, and advanced functions. This topic describes typical function definitions of smart metering sockets.

Advanced functions

With Cloud Timing enabled, you can set recurring tasks from Monday to Sunday to regularly switch on or off a device. The scheduled tasks support automatic adjustment for daylight saving time (DST).

Function description

Energy metering

Added electricity: reports incremental power consumption of the device.
Current now, voltage now, and power now: real-time parameters of the device. If a certain threshold is exceeded, actual values are reported to improve data accuracy.
Power coe, electric coe, and electricity coe: calibrates metering data.
Error: reports various fault values such as overcurrent, overvoltage, overpower, and undervoltage.

Bitmap Fault value

Bit0 ov_cr

Bit1 ov_vol

Bit2 ov_pwr

Bit3 ls_cr

Bit4 ls_vol

Bit5 ls_pow

Bitmap	Fault value
Bit0	ov_cr
Bit1	ov_vol
Bit2	ov_pwr
Bit3	ls_cr
Bit4	ls_vol
Bit5	ls_pow

Advanced timing

Cycle timing: You can set up to 10 cycle timing tasks. Every 10 bytes are described as follows:
- Byte 1: indicates the channel ID. Bit 0: switch. Bit 7 to bit 1: channel ID.
- Byte 2: indicates the week. 00: only once, 01: Sunday, 02: Monday, 04: Tuesday, 08: Wednesday, 10: Thursday, 20: Friday, and 40: Saturday.
- Bytes 3 and 4: indicates the start time. Unit: in minutes.
- Bytes 5 and 6: indicates the end time. Unit: in minutes.
- Bytes 7 and 8: indicates the enabling time. Unit: in minutes.
- Bytes 9 and 10: indicates the disabling time. Unit: in minutes.
Random timing: You can set up to 16 random timing tasks. Every 6 bytes are described as follows:
- Byte 1: indicates the channel ID. Bit 0: switch. Bit 7 to bit 1: channel ID. A power strip has 0 to 6 outlets.
- Byte 2: indicates the week.
- Bytes 3 and 4: indicates the start time. Unit: in minutes.
- Bytes 5 and 6: indicates the end time. Unit: in minutes.

Restart status

Enumeration values of power status setting are described as follows:

none: The indicator light is steady off. This value is recommended for use at night, ensuring a good sleep for users.
relay: The indicator light denotes the switch status. The indicator light is on when the switch is on, and the indicator light is off when the switch is off.
pos: The indicator light denotes the position of the device. The indicator light is off when the switch is on, and the indicator light is on when the switch is off. This value is recommended for use at night, so as to help users quickly locate the socket. It is similar to the function of the fluorescent strip in a traditional socket.

Power status setting only applies to power indicator lights for I/O control or indicator lights that are reused as a power indicator light.
