Saris Speed Sensor Not Pairing

Hello, I got a Saris Fluid Trainer 2, with a speed sensor, and have been riding for about three weeks on it. Tried to go for a ride today, and the speed sensor wouldn’t wake up. I took it off the back wheel, took the battery out, put it back in, and the light came on. Once I put it back on my wheel, it wouldn’t wake up/ pair to Zwift. Any recommendations?

Are you using a hub mounted sensor or a spoke mounted magnetic sensor? The magnetic sensors can be a bit touchy if they don’t tighten up well enough on your spokes or if they get bumped so the magnet doesn’t line up just right with the sensor.

Downgrade companion app to version 3.31.1, if you are using it.

Hi @Stefan_Giegucz

From what you’ve explained, it sounds like you reseeded the battery, but didn’t replace it, correct? Have you tried using a fresh new battery instead?
