A raw_result is a type of MQTT message published by almost every data acquisition module of the SiteController to the MQTT topic raw_result/<gateway_id>, it contains the values read by the module, normally (but not restricted to) as numbers or strings, without any processing applied. A raw_result message can contain the value read from 1 or more sensors, the used format is always JSON. This type of messages are not retained in internal storage nor sent to the cloud.

A raw_result should comply with the following structure:

raw_result message structure

{
    "error_code": <int>,
    "result_dict": {
        "sensor_1": {
            "changed": <true | false>,
            "value": <value read from sensor/data point>,
            "err_code": <int>,
            "err_desc": "<textual description of the error>"
        },
        "sensor_2": {
             ......
        },
        "sensor_3": {
             ......
        }
    },
    "partial": <true means this raw_result can contain just some sensors associated to the sensor_gateway, false or absent means all sensor are present in every raw_result message>,
    "sensor_gateway_id": "<identification of the gateway associated to this sensor group>",
    "timestamp": "<message timestamp in ISO8601 format>"
}

Field definition

Name	Purpose	Optional	Default value
error_code	Error code classifying the whole raw_result	No
result_dict	dictionary with every sensor read, see the next table for more information	No
partial	true means this raw_result can contain just some sensors associated to the sensor_gateway, false or absent means all sensor are present in every raw_result message	Yes	False
sensor_gateway_id	Identification of the gateway associated to this sensor group	No
timestamp	Message timestamp in ISO8601 format	Yes	current timestamp

Field result_dict

Name	Purpose	Optional	Default value
changed	Mark the specific sensor as been changed in comparison with the last reading	No
value	Value read from the sensor, this can be a number, boolean, string.	No
err_code	Integer value representing a error about this specific sensor, 0 means no error, any other value means a error specific for the device, this value have higher relevance than error_code from raw_result	Yes	0
err_desc	Textual representation of the error	Yes	""
