There are a couple options for you:
1... You can use the v.2 RS-485 protocol found here:
http://documents.ekmmetering.com/Meter_ ... AMR_v2.pdf
This is a simple request response string that returns most of the data that is stored inside of the meter. If you use our free software and a serial sniffer software it will simplify your job to be able to "see" the request and response. The v.2 meter protocol uses a Mod 128. We use software called "Advanced Serial Port Monitor" to "see" or "sniff" the serial traffic.
30 represents a 0, 31 represents a 1, 32 represents a 2, etc.
2... The better option will be to use our forthcoming EKM Push system. It cannot be used with your v.2 meter (EKM-Omnimeter v.3 only) but will be the most powerful if you want to get your meter data onto your server.
The EKM Push System uses our EKM-OmniMeters for metering, but instead of having to send requests from a computer and having the meter respond over the network, the EKM Push gateway handles all of the meter communication, parses the meter data, and inserts the reads into a central database. This completely eliminates all of the configuration issues of firewalls, dynamic IP, and having a computer running all the time to make it happen. Data is available seamlessly and immediately from a known, fixed location. Up to 256 EKM-Omnimeters can be daisy chain connected to each EKM Push on up to 4000 feet of wire. The entire system has been designed to be a robust metering system, with an easy plug-and-play installation.
We are focusing on providing our customers with easy access to their data.
If this of interest to you, take a look at this data from live meters that are spread all over the world:
http://collector3.ekmmetering.com
The sample Group ID is: 2 and the Password is: 54321
Firefox works well for viewing
Good meters to check out: 10068
These are rudimentary graphs meant to convey the abilities of this new system.
You can change the number of reads to 360 or 720 to see more history

Or this web data dump:
http://collector3.ekmmetering.com/10068 ... Mjo1NDMyMQ
--------
Or in Linux command line or Mac OSX Terminal (this is a curl command for 300 reads from meter 10068, this is useful for developers, be sure to include "curl" first):
curl http://collector3.ekmmetering.com/10068 ... Mjo1NDMyMQ
I will paste is an example of what this command line curl data looks like below (this much data takes about 1/2 second to retrieve).

Here is a widget we have been working on that is using live EKM Push Data (doesn't yet work with Internet Explorer 8). We can share the code for this if you are interested:

Our intent is not to get into the data business, but to provide the end user with the data and let them do what they want with it, whether it be nice dashboards, billing systems, or other kinds of reports. We will be providing some minimal user interface. But the idea is that for anyone who wants more than that, they will retrieve the data from our server on a regular schedule, we'll dump the data once it's confirmed that the data has been transferred, and they'll do what they need to with the data. At the level of 1 minute read intervals with one day retention, our plan is to provide the data for free. This system was designed and built for us by a brilliant software/hardware engineer, and his forte is reliability. We're extremely pleased and excited by how robust this system is, and how fast it responds. I really believe that this will give us a huge advantage in terms of making our meters a really compelling product.
If you have any questions, or need anything at all, please let us know.
Thanks,
