I’m looking for a way to keep track of the amount of money on the laundry card I have. Currently I have automations set up that display the time remaining on the dry or wash loads in the front end as well as announce through google assistant and notify through push notifications when they are done. I would like to additionally subtract a value from a counter such as 1.60 each time I run as wash cycle as well as being able to add in a larger value when I add money to the card.
The issue I am running into is the counter integration seems to only support integers. Is there anything more elegant then having my laundry card value displayed as 2000 then having the automation decrement 160 each time I run a load?
