Suppose I have my gas meter replaced and the new meter does not start at zero.
On this page: Sensor Entity | Home Assistant Developer Docs it says:
“The value when the sensor reading decreases will not be used as zero-point when calculating sum statistics, instead the zero-point will be set to 0.”
Then a table is shown where the meter is reset to 5 and it will add 5 to the sum (because it sets the zero-point to 0 instead of 5) which is actually not what I want, if I get a new meter that starts at 5 I want it to use 5 as new zero point and add 0 to the sum.
Is it only me not understanding the documentation or is it true that the case of a meter replacement with non-zero starting value was forgotten to be implemented? How would I reset the meter to a new starting value (non-zero) and not mess up the sums?
