EKM Metering

Hi.

While my omnimeter is working fine, I'm looking for a push application or some means to write data to a network attached storage unit in a csv file. I've looked at Encompass which may work for me but I didn't want to go down the third party cloud direction. I have an RS485 to USB adapter running with EKM Dash V2.3.1. I also have an iSerial which failed very early in the piece (it lights up but won't connect to an ethernet port). From what I read, my V2 may be too old to do much with.

This has been brought about by the imminent replacement of my solar power system due to age and the want to track results.

Is anyone able to offer some guidance?

Cheers

Hello Dayle,

For your Omnimeter, you can do one of these things to get csv data to your local storage (with the constraint of not wanting to send data to the cloud):

1. Read the Omnimeter with a computer and the EKM Dash software using a USB converter, then in Dash you can export the data as a csv file. The downside to this is you need to run your computer and Dash software 24/7 to gather all of the data.

2. Read the Omnimeter with your own software and a USB converter and store the data to csv locally. Here is information about the RS485 protocol: https://documents.ekmmetering.com/api-d ... unications

3. Read your Omnimeter with an EKM Push3 and then get the data via the LAN API (which is in json format) then convert the data to csv.

4. Read your Omnimeter with an EKM Push3 which is connected to a USB drive or a large SD card, then you can gather the data off of the USB drive or SD card, the data is also in json format in this case and would need to be converted to csv data.

5. Read your Omnimeter with the Push and send the data to the cloud, then gather the data from the cloud in csv format. You can gather both real-time and historical data in csv format from our open API. This would be the easiest and most reliable option. Here is information about our Open APIs:

For your old 23EDS-N v2 meter (an oldie but goodie by the way): if it is still kicking, you can try connecting it to your EKM Dash software (Im not sure if it will work or not to be honest) with the USB converter. Or if you are a coder you could write some software to communicate with it over RS485.

I will attach the meter communication parsing for the v.2 meters below (v.3 is different). We created that document in 2010! This meter uses a Mod 128 checksum. It is a simple request, response string. 90 percent of the data is returned from the meter with this request string.

30 represents 0, 31 represents 1, 32 represents 2, etc

Hi Jameson.

I'd be keen to go down the Push 3 road but my understanding was it won't talk with the Omni V2. Could you clarify? With the Push 3 connected to WiFi and a fairly substantial SD card, how do I map to that given a known IP address? Does the Push 3 have its own url? In any event the cloud solution is looking easier.

Thanks for your help

The EKM Push3 will communicate with any of these meter models:

Omnimeter I v.3
Omnimeter II v.3 UL
Omnimeter Pulse v.4
Omnimeter Pulse v.4 UL

We hope to add more meter models in the future.

It will not communicate with the older EKM 23EDS-N v.2 or any other v.2 meter models.

When you have a Push3 connected to your network, it will show up as an IP on your LAN network. If it is also connected to the cloud, the LAN IP is posted to the cloud, so it is easy to access via the LAN IP. If you were to go to that LAN IP address you could access the web interface of the Push3 gateway itself:
