Hi,
I use PROP_FLAG_TIME_SERIES as a param properties. but the rainmaker app show No chart data. The real-time data is display normally.
The time_series data does store in cloud?

Code: Select all

    param = esp_rmaker_param_create(CUSTOM_PARAM_BATTERY_VOLTAGE, CUSTOM_PARAM_BATTERY_VOLTAGE_TYPE,
        esp_rmaker_float(app_get_current_battery_voltage()), PROP_FLAG_READ | PROP_FLAG_TIME_SERIES);

The China deployment of ESP RainMaker does not support Time Series data due to the unavailability of the required AWS service. Please use simple time series data instead. It would not have all the aggregations possible with the full-featured time series data, but it will still give you a graph of raw values.

Usage:

Code: Select all

    param = esp_rmaker_param_create(CUSTOM_PARAM_BATTERY_VOLTAGE, CUSTOM_PARAM_BATTERY_VOLTAGE_TYPE,
        esp_rmaker_float(app_get_current_battery_voltage()), PROP_FLAG_READ | PROP_FLAG_SIMPLE_TIME_SERIES);

Thanks。
By the way，Which cloud region the esp32 connects to is determined by what? Is it determined by the Rainmaker APP？
If I install and use the app for the global region, can I connect my device to the global cloud, even though I am geographically located in China.

With Assisted Claiming which I mentioned in the other forum post, the phone app sends the certificate and MQTT URL during claiming, which happens during Wi-Fi provisioning. Whatever region your phone app is set to will get used, irrespective of your geographical region. However, note that if you change the region setting of your phone from China to some other country or vice versa, you will have to erase the flash and then redo provisioning.
