Davis Weatherlink Console history data not loaded

[jkoskela]

I've recently purchased the new Davis Vantage Pro 2 station with the Weatherlink Console (6313). I've tried to CumulusMX (3.28.6 build 3283) to download historic data, but no matter what I do I always get message "No historic data available" after the data was downloaded. I used the -debug parameter and discovered that it did download data but doesn't seem to process it.

I checked the Cumulus code, and I think the problem is the sanity check that is done for the downloaded data:

Code: Select all

			// Find the WLL baro, or internal temp/hum sensors
			if (histObj.sensors[i].sensor_type == 242 && histObj.sensors[i].data_structure_type == 13)
			{
				var recs = histObj.sensors[i].data.Count;
				if (recs > noOfRecs)
				{
					noOfRecs = recs;
					idxOfSensorWithMostRecs = i;
				}
			}

I think the problem here is the data_structure_type. According to Davis documentation (https://weatherlink.github.io/v2-api/da ... ture-types) the type 13 is for WeatherLink Live console, which is different from the WeatherLink Console that comes with the Vantage Pro stations nowadays. I checked the api response from WLL when loading history data from my station and it does have this:

Code: Select all

    {
      "lsid": 710469,
      "data": [{},{},...],
      "sensor_type": 242,
      "data_structure_type": 20
    }

Is there anything I could do to get the data recognized correctly and loaded into history?

Could you please zip up the contents of the MXdiags folder of your installation and attach it to a reply to this topic. We can see what's going on then.

Would it be enough to zip the one log file (20240328-084821.txt) when I had debug on and where it attempted to load history data for one week?

Oh, I forgot to mention the JSON data I pasted in the message from the API response has been shortened to not include the array of real values. I've edited the original post.

Thanks for the report.

That sanity check does need updating, but there are also missing decodes for the WLC archive records of baro, internal T/H, soil/leaf.

The v4 Beta has been updated to make these changes, I intend to release that v. soon. I'm not sure when the next v3 release will be made.

Here is the content of MXdiags. This contains two attempts to load history data, one as station type Davis Cloud (WLL/WLC), and the other as Davis Cloud (VP2).
