I have a Rachio 3 controller. My wireless flow meter was installed underground and by a Rachio-recommended installer a few weeks ago. The signal from the flow meter has never been worse than good. Nevertheless, every time the sprinkler system runs, at least one zone shows high or low flow detected. The particular zone varies. I have had the installer recalibrate and check the system for leaks, etc, once. I have recalibrated the whole system once, and individual zones multiple times. Neither the installer nor I know what to do at this point.
Any ideas? Thanks, Adrian
