I am using a sensor with state class total_increasing to track my propane usage. I look at the number of gallons of empty capacity in my tank and use that as an indication of how much I have used. The problem I am running into is that the tank is never completely full or empty and the limits on both sides fluctuate.
The docs explain that the total_increasing class will always use zero as a “zero-point.” The result for my scenario is that when my tank was filled I see a big bump in usage (error) because it was not filled completely. They fill to 80-85% typically.
Any suggestions?
