Title: "RAW" Data - what exactly is it?
Post by: hnrsoftware on March 09, 2013, 11:37:48 PM
I've been having serious difficulty in "configuring" my TED system with two main breaker panels and a solar PV system feeding into one of them.  My gut, and what I can glean from documentation suggests a layout of "adjusted load, generation and load", but each time I try to use this, the data does not seem to make sense.  Note, I am just recovering from an MTU failure, so I am having to re-confirm the data oddnesses.  At the moment, I'm just trying to establish a baseline of data, extracted to csv for external analysis.

This particular question is "what exactly is the "RAW" data which can be exported?"  I had assumed that it was simply an export of MTU readings without any "layout" processing added - "raw" readings.  I am starting to suspect that "RAW" simply means "compressed", and the readings themselves are already processed with the layout parameters of "load, adjusted load, stand-alone Net...".  The "RAW" export format is much faster to fetch in large quantities (say 2 days of minute readings - 2880 separate records).  I can certainly understand that the small processor used in the gateway would not be particularly happy converting to a verbose format such as XML, but it doesn't seem like the base64 is saving much in exporting to a CSV format.  I will trust that it must help somehow, but I would like someone to confirm whether this data is truly "raw", or just a compressed transmission format of the already processed stored readings.

Either this is a pretty unused forum, or it just isn't monitored very often.  I don't think my question is all that difficult.  The reason that I don't just figure it out by trial and error is that every time you use the "write to device" "Update" in Footprints, the data (at least) glitches - missing or extra data records, and I have seen no documentation to tell me whether, or how it will change history data.  All in all, I would just prefer a yes/no answer to the question from the people who designed the data.  :-}  Howard

Good afternoon hnrsoftware,

I apologize for taking so long to get back to you, I had to verify some information before I replied.

If you are asking about the 5000 series export data, it is base64 raw values that are exported.

Thanks for your question!

Well... that is sort-of my question.  What I want to know is whether the "RAW" power reading it truely "raw" - a signed value that is independent of the layout settings in Footprints (Generation/Load/Adjusted Load...), or whether the returned "raw" values are actually the same values that footprints would be displaying/graphing - some as absolute values, some always negative, some "adjusted" by other mtus...

I understand the base64 aspect - it is the "raw"-ness that is unclear.

Nowhere (that I can find) is it documented precisely how those layout settings affect the mtu the data, and how the settings interact with each other.   At present, I have all three MTUs set as "Stand-alone Net", because they at least provide rational values.  Footprints dashboard doesn't really like stand-alone net, but every time I try to change the settings, I get odd results.

If I could trust that the "raw" values really are "raw", I could change the layout without losing data and history.

Good afternoon hnrsoftware,

According to our software engineer and Tech Support, the values exported are what Footprints displays. As for what each setting does you can find a breakdown here:,2532.0.html. I hope this answers your questions.

Have a great day!
