How to fix statistics data (e.g. energy data)

Hey I have managed (I think) to solve the issue which was bothering me for a long time and I have decided to share the solution with you guys. I hope that someone finds it helpful. Problem I have OWL energy sensor which sends the data via RF433. The problem is that sometimes the received values are not correct. Pretty often I get “0” as the energy_total and once the value jumped significantly by 78M. [image] I don’t have the sensor data to investigate what has happened that day and what wer…

This introduces a massive spike in energy use in home assistant. I have created a filtered version of the raw sensor (sensor.total_yield) to fix the issue: template: - sensor: - name: "total_yield_f…
