EKM Metering

Please explain the readings on the EKM Push Widget.
The options on the bottom of the widget have three buttons. 100-500-1000. What do these # represent?
What is the vertical scale? None shown on my widget.
At times the color coded line graph disappears. Is this normal?

How do I download the EKM Push Real time metering widget.

I have two 400 amp single phase services serving one residence. I currently am using 1- Omnimeter for each service. Do I need to install two Push meters or can I daisy chain the two omnimeters together and receive readings specific to each service?

So where is this data stored and how is the data retrieved. I do not see the time stamp on the EKM Push info

Does the EKM Push or Push Plus have the ability to display data by date and time and retain the data?

I purchased V2 of the EKM software. Is V3 a no charge download upgrade for V2 paid accounts?
