This might be a stupid question, but I am wondering how home assistant manages total_increasing sensors.
If the state of these sensors keeps increasing without any reset whatsoever, it will not “blow up” at some point? By blowing up, I mean that there may be precision issues due to vary large floats.
The statistics are stored as DOUBLE, so they can store insanely large numbers (see here), so for all practical purposes you will never blow them up in HA. They are held as a fraction times 10 to the power of an exponent, and the number of decimals in the fraction is limited (but still way more than HA would ever use).
