The secondary challenge here is that the unit isn’t actually broadcasting your speed and/or power via ANT+. Instead, the app has to convert the speed using the known power curve to display power to you in the app. It’s really too bad that the unit couldn’t simply do that straight forward calculation internal to the sensor and then broadcast speed/power as true ANT+ to any head unit. That way you could simply connect a unit like a Garmin Edge or other bike computer to get more information straight into that device.

Ich schätze das der Sensor die Geschwindigkeit der Schwungscheibe übermittelt, die ist aber wesentlich kleiner als ein normales Rad. Zudem steigt der Wiederstand exponentiell an, d.h. 4 RPM mehr der Schwungscheibe ergibt exponentiell mehr Watt.
