I just installed a ver 3, works great. Will the flow meter be available as a separate purchase for upgrades? Like to try that out too.
Rachio mentioned in another thread that you can buy one separately now, just not directly through the website. Send an email request to firstname.lastname@example.org. You will be sent back a personalized invoice after which you can click a link allowing you to enter payment & shipping address details.
Once you write email@example.com it will take about a day for the response. I ordered mine the same way.
Buy Rachio flow sensor separately?
