Power Meter Accuracy - Another Update

So I've left it just under a week since JSJS Designs got back to me to say they'd updated the WiFi Link and that should make it more accurate.

Here are the results.

Over the period my proper meter states I've used 75kWh.
Over the period my LightwaveRF states I've used 69.9kWh.

So the LightwaveRF readings are now under to the tune of 6.8%.  More accurate than the measurements I took before (it was 31% over).

I will continue to monitor...
