I did a comparison of my Utility company's water meter reading with the flow sensor fed data reported by Rachio. There is a 7% difference, which seems rather high. I'd like to share my data and see if the rest of you might be able to post your data for comparison.
My flow sensor is a CST FSI-T10-001.
When a zone with a few rotary sprinklers is run for 5 minutes, my water company meter measures 41.07 gallons. Rachio reports usage of 44 gallons.
I'm wondering if 7% is within the tolerance of the flow-sensor + rachio integration. For a sensor that costs almost $300, I expected more accuracy than 7% difference. Could the water company's meter be off? I don't know. I'm curious to learn about the Rachio community's experiences.
