When calling esp_rmaker_param_update_and_report, both the parameter value and Time-Series data are reported. How do I report only the Time-Series data?

For Simple Time Series Data, call esp_rmaker_param_report_simple_ts_data instead:

esp_err_t esp_rmaker_param_report_simple_ts_data(
    const esp_rmaker_param_t *param,  /* Parameter handle */
    esp_rmaker_param_val_t val,       /* Value to report */
    int timestamp,                    /* Data timestamp; 0 = use current device time */
    uint16_t ttl_days                 /* Cloud retention in days; 0 = never expire */
);
