I’ve seen some mention this already, but figured I would help explain my process for the Wahoo Kickr 20 and the Wahoo Tickr HRM. Each of those devices allow for multiple simultaneous Bluetooth connections. This is one of the reasons that I chose those specific devices over other options. I run this set up with an iPad and iPad mini or iPad and iPhone.
For the iPad mini or iPhone, I log onto the device and TR app before logging on to the iPad. I confirm my devices are connected and begin my workout. Since I’m in a light warmup, I then log into the iPad and open Zwift. I then select Zwift to use the cadence and power from the Kickr and the heart rate from the Tickr. If controllable is highlighted, I deselect it. Then I choose my route on Zwift and go. Typically, it is ADZ for elevation gain to chase the Tron bike. Sometimes I will choose a different route to complete the badge.
Once I finish my TR session, I usually am done and close out of each. If I feel like going a little further on Zwift, I will exit out of TR on the mini/iPhone and put it to sleep. Then I will go into the menu on Zwift, unpair the Kickr and the re-pair it. I will also select controllable now. Then it is back to riding.
I have noticed that if I don’t actually close the TR app, Zwift will not control my Kickr after the TR session. It is not enough to just put the device to sleep.
One thing to note, if you are uploading each ride to Strava, it will count each ride for mileage and the relative effort/training stress number. If that bothers you, which it does for me, you can either delete one ride from Strava or select one as a commute. If you choose commute, it won’t factor into the relative effort number, but I am pretty sure that it still counts towards your mileage totals. I want accurate miles and relative effort so I simply delete one of the rides.
If someone knows how to select which rides count towards mileage and relative effort only, please let me know. I haven’t figured that out yet.
Hope this helps for those in the Wahoo ecosystem.
