That ANT+ dongle should work with Zwift. You may want to message the seller to make sure it’s USB 2 if you want to be certain, though.
If you’re referring to using your Garmin 810 with Zwift, I do want to mention now that it won’t work. Zwift is not compatible with bike computers or any other devices that only receive data. Zwift reads data, but doesn’t transmit it back. Likewise, these devices do not transmit data for Zwift to receive.
While these computers aren’t compatible with Zwift, you can utilize many of the same functions with the Zwift mobile app (which is free to download on the Apple store and Play store for iOS and Android mobile devices).
Thanks everyone for answer. Already ordered I wasnt thinking that my edge will comunicate with Zwift, but speed, cadance and heart rate sensor, so when i said garmin edge, I thought its bundle
