Generic Sensors de flujo
The integration de sensores de flujo genéricos utiliza la misma API que los sensores de flujo no-genéricos. La única diferencia es que los sensores genéricos deben informar el flujo utilizando la unidad de medida correspondiente a la variable genérica asociada al sensor.
Reporte de flujo acumulado en unidades
The integration de sensores genéricos de flujo por HTTP uses the following structure, que es idéntica a la de los sensores de flujo no-genéricos:
POST /services/gear/DeviceIntegrationService.svc/UpdateFlowSensorValueSummation HTTP/1.1
Host: gear.cloud.studio
Content-Type: application/json
{
"accessToken": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
"endpointID": 1,
"summationValue": 112685,
"timestamp": "2021-02-23T14:55:03"
}Parameters
| Name | Description | Data Type |
|---|---|---|
| accessToken | Access token with permissions to update endpoint information. See this page for more information. | text |
| endpointID | Unique endpoint identifier or combination of device address and endpoint address in format [deviceAddress]:endpointAddress (e.g.: [device-1234]:1). These values can be found on the endpoint management page. | numeric |
| summationValue | Valor acumulado de flujo informado por el sensor. Las unidades son las mismas que las elegidas para la variable genérica asociada al sensor. | numeric |
| timestamp | Optional value indicating the UTC date and time corresponding to the measurement. The date format must match one of those specified in the date formats section. If the field is omitted, the platform will assume the measurement corresponds to the current date and time. | text |
Reporting Accumulated Flow in "raw" Format
Flow can be reported as a raw value using the expression converter. This option is convenient when the device is unable to perform conversions and emits values that need to be transformed before being injected into the platform.
Below is an example of a raw format request:
POST /services/gear/DeviceIntegrationService.svc/UpdateFlowSensorValueSummationRaw HTTP/1.1
Host: gear.cloud.studio
Content-Type: application/json
{
"accessToken": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
"endpointID": 1,
"rawData": "112685",
"timestamp": "2021-02-23T14:55:03"
}Parameters
| Name | Description | Data Type |
|---|---|---|
| accessToken | Access token with permissions to update endpoint information. See this page for more information. | text |
| endpointID | Unique endpoint identifier, which can be found on the endpoint management page. | numeric |
| rawData | Value reported by the sensor, as text. An expression must be specified in the expression converter. La expresión debe devolver un valor numérico indicando el valor acumulado de flujo informado por el sensor, expresado en las unidades de la variable genérica asociada al sensor. | text |
| timestamp | Optional value indicating the UTC date and time corresponding to the measurement. The date format must match one of those specified in the date formats section. If the field is omitted, the platform will assume the measurement corresponds to the current date and time. | text |
