As a bit of a data nerd, I’ve really enjoyed having the 16-sensor Emporia Vue 2 hooked up and have added 8 Emporia plugs to gain additional insights. Installation was straight-forward but a bit of a headache, dealing with the bulky CT clamps and big mass of wires. I have no solar (yet) and probably won’t use the Vue 2 to measure production, but rather focus on my raw consumption. I’ve documented a number of suggestions in the following threads:
Now that I’ve completed my first full billing cycle, I exported the raw Emporia data to compare with my utility’s meter readings and was a bit surprised at the difference between the two. Summing up usage of both mains from the 1DAY log, over the same date range as my meter readings, the Emporia was 7% lower than the utility (98kWh less). Has anyone else seen similar results?
I’ve checked the hourly log and its totals match the daily totals so it doesn’t look like any summation issues on the Emporia side. I’m going to try reading the meter myself at the same time of day on a weekly basis and compare my readings with the hourly Emporia logs for a while to see if it’s consistently lower.
