First time poster.. I for the life of me cannot calibrate the flow rate on my B-hyve outdoor timer. Reading through these forums I saw that you have to be connected via Bluetooth and not WiFi. I did that and the calibration worked, at least until I went into the next field and poof back to zero.. The app is difficult enough, but it just won’t save the calibration and I’m assuming the flow rate is kinda critical to smartwatering.. Any help would be greatly appreciated.
