Cloud API - Get Historical Data - Time Series

[jlunce]

I'd like to download the historical values for a thing variable via the cloud API.

Would devicesV2Timeseries be the correct command?

I have attempted something like this:
https://api2.arduino.cc/iot/v2/devices/ed2037a3-30d6-4218-b0d8-9d2ac3be46dc/properties/4e45eb91-b235-4fe8-81af-91ee6012f97a?limit=100&start=2021-05-07T02:00:00.000Z

But my response is always this:
{"id":"ed2037a3-30d6-4218-b0d8-9d2ac3be46dc","last_evaluated_key":null,"name":"4e45eb91-b235-4fe8-81af-91ee6012f97a","values":[]}

Maybe I'm using the wrong command?

Thanks!

I'm getting the exact same response. I don't think this function is working or the documentation is wrong. Frustrating.

Looking at the documentation, there is a need for the 'ctx' value in the URL?

arduino/iot-client-go/blob/master/docs/DevicesV2Api.md#DevicesV2Timeseries

DevicesV2Timeseries timeseries devices_v2
GET device properties values in a range of time
 * @param ctx _context.Context - for authentication, logging, cancellation, deadlines, tracing, etc. Passed from http.Request or context.Background().
 * @param id The id of the device
 * @param pid The id of the property
 * @param optional nil or *DevicesV2TimeseriesOpts - Optional Parameters:
 * @param "Limit" (optional.Int32) -  The number of properties to select
 * @param "Start" (optional.String) -  The time at which to start selecting properties
@return ArduinoDevicev2propertyvalues

When I look at the on-line documentation: Arduino IoT Cloud API

I am not seeing any need for a "ctx" parameter.

But what is concerning to me is that you seem to be looking at a different set of documentation.

[rumbaar]

Yeah, not sure. The documentation for the IoT Cloud I've found is quite lacking or non-existent.

Where I got the info from is here: GitHub - arduino/iot-client-go: Go client for Arduino IoT API

Which is linked to the Arduino IoT Cloud API documentation you've linked too.

[jmdodd95682]

I think you are looking at the GO code and I was looking at the Python code. Since both versions are seeing the same behavior I guess we can assume it is a basic problem with the libraries.

I've started looking into alternatives...none of which are real good. I've been forced to manually download the data for now.

[rumbaar]

Yes, would be good to hear from Arduino IoT team. Good luck.

Same Problem here...
