This is my current setup:
There are THREE usb ant+ dongles. PerfPro uses one to receive (which I do not use), one to transmit, and one is ignored (which is used by Zwift).
I run PerfPro, and have it control the computrainer. I then turn on the option “simulate power meter” in PerfPro.
I run Zwift, and it does recognize the “power meter”.
When I start pedaling, the wattage comes out on PerfPro correctly.
However, Zwift reads it grossly incorrectly. I know it can pick up a signal, but the wattage jumps from 0 to 500 to 2500 to 0 in a few seconds (and stays at 0 if I continue to pedal). Then when the [physical] wheel on the computrainer stops, it does it again: 0 to 500+ to 2500+ to 0. One *slight* pedal, and it does the 0 to 2500 spiel again (if I do this in the sprint part, I’d probably cover that in just a few seconds!)
Am I doing something wrong? It seems that Zwift is not reading the output of PerfPro correctly.
(PerfPro is transmitting the power data through one USB ant+ – it is simulating a power meter. But Zwift is not reading that output correctly.)
