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.
If it sends the right kind of pulses at 24V, Rachio might be able to read it. They list only selected meters from Badger, CST, Everydrop, FloMec and Toro as known options. Flume is not listed.
