Hello, there doesn't seem to be an 820 forum but I think it shouldn't matter - I have an Edge 820 and often use a chest strap to monitor my HR. I have recently bought an Elite Zumo indoor Smart Trainer, using fulgaz and am trying to get the HR strap to send a signal to fulgaz. That doesn't seem to work? I have downloaded the Elite app but not sure whether that will via fulgaz in the end record my heart rate? Anyone can answer that for me please?
