Kw calculator for house1/20/2024 ![]() You would expect it to change on the hour. The hourly sensor output from the Utility_Meter changes throughout the hour.This does not seem to bother the Utility_Meterīut I wonder if there is a floating point overflow or loss of accuracy when subtracting large floating point numbers. The integration sensor output never resets.Integration Sensor to Utility_Meter flow: 8.463 kWh, error = 12.8%Ĭustom Python Script: 7.5113 kWh, error = 0.15%Ĭlearly, there are issues with the Integration Sensor to Utility_Meter flow. I hope you agree the known good result is 7.5 kWh My power waveform was simple so that I could do my own integration calculation I created a test power waveform and fed that to the Integration Sensor to Utility_Meter flow I’m back to explain why the Integration Sensor to Utility_Meter flow has issues. If you are feeling adventurous, you could pull the code from either (or both) of these and use them as custom components probably until they get merged. On a reset an attribute will store the previous counter, providing the means for comparison operations (“did I spend more or less this month?”) ![]() From a User perspective utility meters operate in cycles (usually monthly) for billing purposes, this sensor will automatically reset the counter based on the configured cycle. This sensor does an integration of Power and time in order to measure energy consumed in kWh (standard energy measurement unit)Ī utility meter sensor provides functionality to track consumptions of various utilities (e.g. Sometimes a device only provides power information (measured in W or kW). Hopefully they are accepted and merged… eventually. There are two components with open pull requests that seem to meet your need.
