Cadence sensor 2 not available in list of device

cadence sensor 2 isn't availabe, you have to add them as ANT+ device on your cycle computer or watch and it only works, when you start an activity, thats normal!

Cadence sensor 2 is also a Bluetooth device, from what I see in others applications: Urban Biker, Ride With GPS, Endomondo, etc. Why in Garmin Connect is not available?

good question, could be, because the speed sensor works with a memory on it and you can sync all your past rides, cadence 2 haven't memory, so for Garmin it's not necessary to add it in Connect

How do you monitors cadence on the phone if you can't connect the cadence sensor from Garmin Connect? Others applications are working without a problem...:)

Garmin Connect isn't a Software to record an activity live, thats a fact and so there is no need to pair the cadence with it live, for live recording i use Edge 1030 or Fenix 5 or Zwift, or you can use Strava or something similar

read this article and you see DC is only pairing the speed sensor 2 with Garmin Connect and not the cadence sensor 2, the automatic records of speed sensor 2 are without cadence from the memory of speed sensor, because cadence have no memory on it, it only can send the data live to ANT+/BLT devices or software what is able to record the data, Garmin Connect can't record any data, only importing from devices or other software

Thank you very much...Now I understand what I have to do...I found some other application that might be useful for me.

Hi! I have a follow-up question I'm hoping you can answer. I will be using my Fenix 5 watch to record my workout live and pull in the data from the speed and cadence sensors. Will the readings from the cadence sensor be available in Garmin Connect (and subsequently Strava after exporting the workout to Strava) after I complete the workout and sync to Garmin Connect?

why not?
