Identical Meters, 1 updates volts, 2nd does not

I have 4 Meter Switches that are capable of updating amps/volts/watts.

After repeated repairing two of them show this data, 2 do not. I believe this is due to the upnp or device file. All are shown as properly configured.

Can I copy the config from one device to the others to properly poll all variables?

It would be of great help if you advised us of who the manufacturer is and what Vera you are using?
