I tried the data file source with a CSV file that I've previously used to import some data to a point using the 'import data' function. I would expect that they use the same method for parsing data but, having skimmed the help file for the data file source (you have to write your own classes?), maybe not..

I couldn't get my data file source to work, but I didn't try very hard to figure it out, and it's not clear to me whether you need to create points for the DP_'s that you're importing, or what.
But maybe you'll find my CSV of some use anyway. I notice that you wrote 'TIME' but my file has 'Time', for example.

Are you running Mango as root? Maybe it's a permissions issue.

Hello,

I would like to understand how the "valueRegEx" to be used against a JSON string in mango.

"pointLocator":{ "dataType":"NUMERIC", "ignoreIfMissing":false, "timeFormat":"", "timeRegex":"", "valueFormat":"", "valueRegex":"\"id\":\"10001\",\"type\":\"batteryzone\".*?\"dcvoltage\":\"(.*?)\",\".*?\"currinputs\"" },

I know its gets the dcvoltage from the json string but don’t know how it terminates (I’m assuming currinputs match). I want to start from a different point in the json string.

Thanks,
Gary C

When delete a datapoint, the meta datapoint used this datapoint will be affect, Can do some caution when delete one datapoint which be used in another meta point. :mrgreen: :oops:
