I had something odd happen during today’s tour of the Island. First, my trainer setup consists of a Wahoo KICKR trainer, a Wahoo Blue SC Speed & Cadence sensor, and Wahoo TICKR+ heart rate sensor. At ~25 minutes into the ride, the Zwift software lost control of the KICKR. The first thing I noticed was the Zwift Power output display briefly went to zero. The Power output returned within seconds, but the KICKR resistance no longer changed based on the grade. My guess is the KICKR mode was somehow changed/reverted to resistance mode. My understanding is the KICKR should be in Sim mode during the Zwift session. Unfortunately, the only way I could get the KICKR back into Sim mode was to exit the Zwift session and restart it. I don’t recall now, but I don’t think simply unpairing the KICKR, and then re-pairing it while still in the Zwift session worked.
This happed to me once before (~1-2 weeks ago), but I didn’t report it. At that time, I did a little browing through the Zwift Support topics and it occurred to me that the problem may be related to a temporary loss / interruption of the ANT+ connection. I repositioned my ANT+ dongle to be closer to the KICKR (closer and with no obstructions). My setup has remained in that position since that time and I have had no further problems until today (and I have used Zwift daily).
Since loss / interruption of the ANT+ connection with the KICKR is probably going to happen from time to time, would it be possible for the Zwift software to recognize when this happens and place the KICKR back into Sim mode?
