Have been using the same setup for well over a year. Wahoo Tickr HRM connected to both Wattbike and ios iphone 7. HRM seems to connect happily to both devices and deliver the info. Today, wouldn’t connect to zwift app (not companion app btw). Today it connects to the WB as usual but Zwift app won’t find it. So I ride with HR data.
Not only that, but NOW the zwift app won’t allow searching for an HRM - only allows connection to a power sensor or a speed sensor. And there’s no way to change that. I’ve changed the battery on the HRM just in case, but it connected to WB fine so I don’t think that’s it tbh. The app feels like you’re just a lucky passenger if it all connects, but can’t really see or control settings if not.
Has there been some sort of (ironically titled) update to the app?
