Been trying to pair it since Memorial Day, and it refuses. Held my phone next to it to see if I could see it with a Bluetooth scan and NOTHING. Sent at least 2 requests in for help and still received no response as of today.
Flow meter is not operating on a Bluetooth protocol or frequency. It is designed to communicate directly with Gen 3 controllers. During the pairing process the batteries need to be removed and reinserted during an appropriate step of the process as guided by the Rachio app.
It is a proprietary protocol, designed by Rachio specifically for this application. Communication is done over 915 Mhz frequency (vs bluetooth’s 2.4 GHz).
@jim06 - I’d pull the batteries from the flow meter then power cycle the Rachio and try to reconnect. If the WFM still won’t connect, I’d PM @Franz your serial number and have them set the firmware on your Rachio back a version to 615 - that seemed to fix it for some.
