Edit: check out the kurt kinetic instructions on connecting an android to zwift: https://www.kurtkinetic.com/training-blog-feed/getting-started-with-zwift it might be more helpful than my tips below
i had a similar struggle trying to connect my Kinetic InRide sensor to Zwift on my Macbook today. I opened Zwift on the macbook and it couldn’t find the sensor even though bluetooth on my mac was turned on and I was pedaling. (I also had no problem getting InRide sensor to connect to the Kinetic App on my iPhone).
I ended up giving up on bluetooth on the macbook and in Zwift, clicked the gear icon from “Use bluetooth” over to “Use Swift Companion”. Then on my iPhone (which is connected to the same WiFi as my Macbook), I opened the Kinetic app and made sure I disconnected the InRide sensor first, then closed the Kinetic App. Then I opened the Zwift Companion app on my iPhone and clicked on the bluetooth icon. At first it said to open the Paired Devices window in the main Zwift app (on my macbook), but then the Zwift Companion App found my Kinetic inRide sensor, and all of a sudden the InRide sensor showed up in Zwift on my Macbook and I was able to ride.
So key points:
*I had success using two devices, one macbook computer (with Zwift installed) and one iphone (with zwift companion installed)
*Zwift bluetooth on my macbook didn’t find my kinetic InRide sensor ever
*Zwift was able to find the InRide sensor using the Zwift Companion App
*Both devices must be on the same wifi
*Both devices must have bluetooth on (but more importantly the iphone)
*Download the Zwift companion on your phone and Zwift on the display device
*Disconnect the InRide sensor from the Kinetic app in settings. (you could toggle bluetooth off/on on your phone to be safe)
*Make sure when you open Zwift at the “Paired Devices” window you change “bluetooth” to “use zwift companion”
*open the Zwift companion app on your phone
*When the InRide Sensor shows up in Zwift, select it in “controllable” and/or “speed”, “power” and “cadence” until you see the start button appear.
Edit: these steps I went over above to use the companion app are detailed here: https://support.zwift.com/en_us/pairing-to-zwift-with-bluetooth-le-ble-cycling--S1xnpAdrX the steps are the same for iphone/android. The Native BLE option didn’t work on my macbook at all.
It took me some experimenting to figure out but I hope this helps. Was definitely a little frustrating to figure out, and I do IT support for a living.
I don’t know how it might work with one device. Maybe you could have the Zwift companion and the Zwift app open on one device? Not sure.
