According to Rachio, Gen 3 has the following features:
- Leak detection and blockage notifications
- Low-flow leak detection with highly-accurate Vortex technology
- Instant zone shut-off triggered by leak detection
- Precise outdoor water usage monitoring
Where do I find them? How do I set them up?
All these features you list are supported by Rachio Gen 3 provided you also have a flow meter connected to it. The “Vortex technology” terminology applies to SOME compatible flow meters, including a wireless one previously marketed by Rachio. There are lots of other styles too. The technology of the meter isn’t important to Rachio, just the signal it sends.
