I posted this info in another thread, but I thought I should break it out into its own thread.
I would like to see you guys support Rain Bird flow meters (they are actually made by Data Industrial, which I think is owned now by Badger).
They make a good series of brass flow meters for those with metal pipes.
Here is the info I think Rachio needs to set them up in their system
This data comes from this manual: https://www.rainbird.com/sites/default/files/media/documents/2018-02/man_RainBirdFlowSensors.pdf
They also have other types that maybe other customers use. They all seem to be listed in the above manual.
