Started receiving zero flow warnings last week after working for a month or two. Just got a chance to troubleshoot this weekend. Tried the following. None have resolved the issue. Attempted re calibration of a single zone after each item below.
- Reset Rachio Controller by unplugging/power cycling
- Reset flow meter by pulling battery and reinserting several seconds later. Solid Green light was shown on Flow Meter.
- Unpaired and Re-setup Flow meter.
- Attempted full zone re calibration after repairing and still was shown 0 flow. Pressurization time was 3 minutes for each zone. Zones appear to be watering at normal pressure.
Signal and Battery shows good/excellent in app. Full calibration shows zone one flow measurement on calibrating screen all others state Waiting after zero flow warning.
Zone 1 shows Baseline Calibration today at 9.4 gpm (which sounds correct). Other zones also showing baseline calibration. But still get Zero flow warning on every zone.
May have started when I implemented a daily flex schedule in Zone 1 but can’t recall if it correlates.
