I’ve owned the Rachio wireless flow meter for several years and use it with my version 3 controller. I just launched the app (iPad) for the first time in 2025 and can’t find the option to calibrate the flow rate. Has this been removed?
Edit: turns out my WFM displayed as Disconnected, batteries were probably bad. Replaced batteries and tried to PAIR bur it failed repeatedly. WFM never showed a green light. Any ideas?
Edit: magically, it automatically reconnected after about 30 minutes or so! I received an email stating, The Rachio Wireless Flow Meter linked to your Rachio-EB7A54 controller reconnected at 02:42 PM.
