No. I use a Garmin remote with Edge 1030 since ever and Ebike app works fine nevertheless.I added the sensor for the Garmin remote after it started to work. Is that sensor preventing the Garmin from displaying the battery and assistance level properly?
I suggest to go to setup of Ebike IQ-app, type in „0“ (zero) in line of ID number - that deselects your Levo. Then turn off your Edge completely and let it boot.
Then connect your Levo anew.
