Homekit addon do we have possibility to add Water mesauring device with let HMCharacteristicTypeWaterLevel

is there a way to add a accesory like Water consumption meter into homekit accesorry?

i don’t see a accessory of this type in homekit developer other than water level which is 0-100% and i rather need a increasing number without limitation.

it seems homekit is not inline which any measurements like energy / water etc ?
