I am trying to build my own ESP device to measure both battery % left and how much propane is left (based on my hall sensor reading).
I keep getting device_class errors.
Apparently I can't use unit_of_measurement: '%' with device_class volume, nor with device_class voltage.
For the latter, I get that I should use device_class: battery,
but for the remote hall sensor that measures how much propane I have left, neither volume nor gas allows for unit_of_measurement: '%' without errors. Am I supposed to call my propane tank a battery?
