@Frankge ,
For me Home Assistant didn’t give me access to the zone running information, so I finally broke down and did a short script that pulls data from the Rachio and Flume APIs and overlays Flume usage with Zone information. Since my sprinkler cycles run late at night and early AM, there’s no other water flow activity so this approach works. See the chart below. My Flume also picked up a slow leak in my sprinkler line that started a couple days ago, and I fixed yesterday - that’s the 0.09 gpm flow baseline when my sprinkling is off.
Can share how I did it if you want.
