Well, I was trying to troubleshoot (not yet finished; but here are the results so far). I think the problem may lie in any one (or all) of these areas:
1. Zwift not reading the power correctly (that PerfPRO is transmitting);
2. PerfPRO not transmitting the power correctly;
3. Some of the USB ant+ sticks...
Anyway, I know that PerfPRO is transmitting correctly, because on an app on my phone, my phone is getting the correct readings.
The USB ant+ sticks are also working (I changed them into different combinations).
Zwift and PerfPRO are not fighting for control over the CT, methinks; I assign the CT to either Zwift OR PerfPRO, and to whom I assigned it is the one that controls it (in this case, I want PerfPRO to control). Besides, in the options of pairing Zwift with either the CT or the simulated power via ANT+, I already chose the ANT+ option (and if I run PerfPRO first, then the CT option is actually not available to Zwift -- first come, first served, I guess!).
Right now, I can't properly run the two together (unless I end up fluctuating between 0 and 2500+ watts - sure to get the ire of Zwifters everywhere; I'm sure the green jersery would be out of reach of even Kittel and Cavendish, haha)
I don't have a power meter, so cannot further cross check.
My next plan of attack (maybe later in the afternoon or so), is to switch USB hubs. Maybe three of them together in one hub is no good.
At least I know that PerfPro is transmitting correctly. And that the ANT+ sticks are fine. Right now, boils down to either Zwift not reading what PerfPRO is transmitting, or perhaps three ANT+ sticks in the same hub are causing issues.
I see what you're saying now. I think this would be a problem with Zwift then. If your phone is correctly reading the power transmitted by PerfPro from your computrainer then the power signal should be good for zwift. I'd try reaching out to Zwift's customer support or facebook page and tell them your problem.
Maybe it'll make them get workouts rolled out sooner so you don't have to do a complex set-up like that!
Another thing might be that perhaps your ant+ stick that is being used for the power transmitting is not USB2. If you look in the help file under Power Meter Simulation it recommends a USB2 stick. But again, if it's showing correctly on your phone, i would think zwift should be able to pick it up correctly as well...
And last thing I can think of is perhaps it's an interference issue. Where is your internet router in relation to the ant+ sticks? Routers can mess up the ant+ signal and cause dropouts or spikes. I had to buy a usb extension on amazon to get my ant+ stick right next to my kickr so that my computer receives the signal correctly. It's possible that your router or something else is interfering with your ant+ sticks, though hopefully they're right next to each other and I'd think they should be okay in that case. Again, I also think since your phone is getting the signal correctly that this shouldn't be an issue...
Just a bunch of random thoughts. I'm not really an expert on any of this, just trying to offer an outsider perspective! I'd definitely contact Zwift if you can't figure it out though. Best of luck!
