Can I compare the Flo data to my water bill to see if I’m being incorrectly charged for water?

This article includes detailed information on the Flo Smart Water Monitor and Shutoff, also known as the Flo by Moen Water Shutoff.

Yes, however, keep in mind that the Flo Smart Water Monitor and Shutoff will not capture the data from fixtures or plumbing lines that are split from or before the Flo Smart Water Monitor and Shutoff, and both the Flo Smart Water Monitor and Shutoff and water meter have a margin of error.
