Hi!
I’m using a Utility Meter to track my energy usage for each day, month, etc., but I’m experiencing an issue with accuracy. There is always a discrepancy between the actual value (calculated as the difference between the last and first values of the day) and what the Utility Meter reports. Below are some images that illustrate the problem:
The expected result should be 21200-21158 = 42 (plus or minus a few decimals), but instead, I get the following:
As you can see, there’s a difference of a few percent.
I have a sensor that reports the total energy consumption, and my code for the utility meter sensor is quite simple:
daily_consumption:
source: sensor.total_consumption
unique_id: 151f5e32-b25d-4b10-990e-53e4b5dff930
cycle: daily
name: "Daily Consumption"
Have I made any mistakes, or is there anything I can do to resolve this? A few percent difference in daily consumption isn’t a huge issue, although it can be frustrating. However, a few percent off in my yearly consumption is more concerning.
Thanks!
