I have 65 irrigation heads and I know they flow 2.3 gallons per minute (GPM). I’m using HA to run the irrigation (using Smart Irrigation). Since HA will know the amount of time the irrigation runs can I use this data to calculate my water usage? I’d like to track the gallons used (and preferably, the cost) and reset it each month. Then I can use that data in my automation to turn off my irrigation if I hit a set monthly budget.
The irrigation integration calculates the amount of time the irrigation should run, I have an automation that runs each zone for that amount of time. Presumably, I could calculate my water usage in that automation somehow. For example, have an action in the automation that calculates runtime * total gpm. But that would just calculate the gallons used during that single watering. What would I use to track the cumulative amount?
