- Took a reading from my proper electricity meter when I installed the power monitor.
- Noted the daily measurements from the power monitor for the remainder of that day and the rest of the week.
- A week later took another proper meter reading and noted the cumulative measurement up to that point.

Power Monitor Accuracy
For the last week I've taken some measurements to see how accurate the power meter is. To do this I:
My meter readings state I used 111 kWh
The power meter readings state I used 145 kWh
So a 31% error.....
I will contact LightwaveRF support as this can't be correct. Another update when I know more.....
