Power Meter Accuracy - Update

I raised a support ticket with LightwaveRF on the accuracy of the power meter. Here's the response I got, (within 12 hours so good timely responses).

Hi Paul,We released WiFiLink version 2.28 yesterday which has adjusted the way the energy monitor calculates usage. The readings are in kWh, yes. You should get better accuracy from yesterday onwards, but be aware the figure given is an only an approximation.Max is kW, whilst the Totals are in kWh.Let me know if this helps!

I did spot the upgrade to 2.28. So another round of measurements, let's see if it's more accurate now.
