After the Sense conf. call on Fri. I got to thinking about how different the data we see on our “power meter” view vs. the actual raw data. In the conference call, the R&D team was able to look at and display each leg’s power consumption individually, but I was also reminded how much goes on below even that:
- The actual 60 Hz current and voltage waveforms for both legs plus solar
- Some of the recognition features that they glean out of the raw current and voltage waveforms - phase angle
- The raw power calculation at each sample in time
- Some kind of single or multicycle windowing and time series analysis to support appropriate RMS results
- Summing the power for both legs
