Weight Sensors
Reporting Weight in Grams
The MQTT integration of weight sensors uses the following structure:
{
"accessToken": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
"endpointID": 1,
"weightGrams": 45,
"timestamp": "2021-02-23T14:55:03",
"mqttMethod": "UpdateWeightSensorStatus",
"mqttRID": "tkrs34"
}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. | text |
| weightGrams | Weight, expressed in grams. | 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 |
| mqttMethod | Service method to call, in this case UpdateWeightSensorStatus. | string |
| mqttRID | Optional request identifier, used to get a confirmation response. | string |
Reporting Weight in "raw" Format
The weight 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.
Here is an example of a request in raw format:
{
"accessToken": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
"endpointID": 1,
"rawData": "25",
"timestamp": "2021-02-23T14:55:03",
"mqttMethod": "UpdateWeightSensorStatusRaw",
"mqttRID": "RXmp123"
}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. The expression must return a numeric value with the weight, in grams. | 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 |
| mqttMethod | Service method to call, in this case UpdateWeightSensorStatusRaw. | string |
| mqttRID | Optional request identifier, used to get a confirmation response. | string |
