@e.braun,
Good suggestion, and one I made several years ago, when I was encountering a number of data dropouts. I’m in the US/California and my utility also allows us to tap into the smart meter Zigbee/Zwave feed to view meter data. I own a Rainforest Eagle and did use to compare against Sense in the early days at an hourly level. Since then, Sense has cleaned up many of the dropout issues and I have cleaned up my WiFi network to the point that dropouts are extremely rare.
My take today is that a link to the meter data feed is a nice to have for hyper tuning CT calibration, but not super useful otherwise. Why ?
- Sense is very accurate: +/- 2% except when acquisition dropouts occur.
How Accurate is Sense vs. Utility Metering? - #15 by kevin1 - More accuracy probably isn’t helpful - Sense is more accurate than my solar inverter when computing the solar component.
- Time resolution - Smart meters only update RMS power data every 3-10 seconds depending on communications infrastructure, so making useful comparisons is hard.
Interesting to hear what you think having a link to the smart meter data feed would improve ?
