Reporting Device Measurement Points in Batch¶
The device measurement points are reported in batch in the following scenarios:
A gateway device reports the measurement point data of its sub-devices.
A device that is directly connected to EnOS reports measurement points with different timestamps.
Both scenarios mentioned above.
Note
Configure the following parameters according to the parameters defined in the model. If part of the data fails to be reported, the entire request will fail, and the first return code that occurs will be returned.

Request Parameter Description¶
Parameters |
Type |
Mandatory/Optional |
Description |
---|---|---|---|
id |
String |
Optional |
The message ID. It is a reserved parameter that is reserved for future use. |
version |
String |
Mandatory |
The version of the protocol. The current version is 1.0. |
params |
Object |
Mandatory |
The parameters used for reporting the device measurement points. |
productKey |
String |
Optional |
The product key of the device. If you need to report the data of sub-devices, the product and device keys of the sub-devices are required. If the product and device keys of sub-devices are not provided, the product and device keys in the upstream request topic will be used instead. |
deviceKey |
String |
Optional |
The device key of the device. If you need to report the data of sub-devices, the product and device keys of the sub-devices are required. If the product and device keys of sub-devices are not provided, the product and device keys in the upstream request topic will be used instead. |
measurepoints |
Object |
Mandatory |
The list of the measurement points to be reported. |
Power |
Struct |
Optional |
The identifier of the measurement point that you want to report. In this example, the measurement point has the identifier Power. The value you set for the point must match the data type defined for this parameter. In this case, the data type for Power is struct, defined with 2 paramters value and quality. |
value |
Integer |
Optional |
The parameter name of the struct data type of the measurement point Power. The value you set must match the data type defined for this parameter. For example, when the data type of this parameter is set to integer in the model, the value here must be an integer. |
quality |
Integer |
Optional |
The parameter name of the struct data type of the measurement point Power. In this example, the quality parameter indicates the data quality. Similar to the above, the value you set must match the data type defined for this parameter. |
temp |
Integer |
Optional |
The identifier of the measurement point that you want to report. In this example, the measurement point has the identifier temp. Similar to the above, the value you set must match the data type defined for this parameter. |
branchCurr |
Array |
Optional |
The identifier of the measurement point that you want to report. In this example, the measurement point has the identifier branchCurr. Similar to the above, the value you set must match the data type defined for this parameter. |
time |
Timestamp |
Optional |
The timestamp of the measurement point. When not specified, the value is the server time. |
method |
String |
Mandatory |
The request method. |
Response Parameter Description¶
Parameter |
Type |
Mandatory/Optional |
Description |
---|---|---|---|
code |
Integer |
Mandatory |
The return code. “200” indicates that the request operation is executed successfully. |
data |
JSON |
Optional |
The detailed returned information in JSON format. |
Return Code¶
