At the end of December, my Wahoo KICKR connected to devices but stopped broadcasting power data.
The connection itself made the problem confusing. The trainer appeared over Bluetooth and the Wahoo application could find it. The expected power reading still did not reach the training setup.
I removed the device and added it again. I checked that another phone, computer, or application was not holding the Bluetooth connection. The indicator continued flashing until I opened the Wahoo app, where the trainer connected normally.
That narrowed the fault but did not resolve it. Basic discovery worked. The missing part was the live measurement used by indoor cycling software to show effort and control a structured workout.
I opened a support case and described the difference between connecting and producing data. That distinction mattered more than saying the trainer did not work. A support technician needed to know that the device was visible, pairing was possible, and power was the missing output.
The trainer was several years old, and I no longer had the original receipt. I included that information when support asked about its purchase history.
The private correspondence contains identifiers and transaction details. They are not included here. The public record does not need a serial number, support-case number, or the name of the person handling the request.
The safe event is ordinary equipment troubleshooting during indoor cycling season. I checked competing connections, removed and re-added the trainer, tested the manufacturer's application, and continued the case with support.
The issue stayed open. The KICKR could announce itself and accept a connection, but the number that made it useful for training was absent.
The final H2 archive entry is therefore not a race or a completed repair. It is a precise failure report sent while the hardware was still being diagnosed.
