Hello all,
I cannot manage to get the total_daily_energy to be accurate. I tried method right, left and trapezoid, it is never accurate, it shows a number of cubic meters wildly different from what the pulse_meter total is showing. Most of the time it’s significantly more.
Alternatively, I would like to use the pulse_meter total, but the energy dashboard does not let me select it, even though device_class: gas and unit_of_measurement: "m³".
Here is the yaml:
