See below. ERG mode, Tallac -1. Top chart is straight TR reported data from my Kickr. Bottom chart is the same ride reported through my Quarq.
Obviously, I hit all the intervals and the trainer adjusted properly for the workout. But why does the chart on TR look like this? I had zero awareness of it during the workout, so obviously TR was sending the commands properly to the Kickr.
I see this same behavior on both short intervals and long intervals, but not really with any consistency. Thoughts?
Sounds like an issue with the KICKR. Power command clearly went up, since you can see actual power measured by the Quarq going up, and even your HR going up on the TR version of the graph. Itâs the actual power reported by the KICKR that stayed flatline. Cadence is also changing on the TR graph during the âsnoozeâ part of that interval - is that coming from the KICKR, or from the power meter?
I would venture an intermittent disconnect between TR and the trainer, such that the new power command did get transmitted, but somehow power wasnât? The simplest patch (and a patch it is) would be to use your Quarq as the power source for TR, and enable power match.

For this ride, I have intentionally not paired the Quarq to TrainerRoad and (obviously) not used anything like PowerMatch.
⌠but now that you mention it, back in the olden-times when I did use PowerMatch and paired the Quarq, I donât recall seeing these oddities. hmmmm.
So cadence is from the KICKR? Makes it even weirder, and points more to the trainer. These issues usually come down to the communication link (BT or ANT+) being dropped, or the sensor source going funky. In this case, one can pretty much rule out the communication link, since the trainer is getting power commands, transmitting cadence, but flat-lining power. Thatâs hard to do on the app side too; highest probability is the trainer.

I wonder if its something to do with the fact that you have power smoothing turned on for the kickr
I think with that on (think being the operative wordâŚthis is a theory) that the kickr broadcasts the power as exactly what is sent - not what is being measured by the trainer. SoâŚthe kickr receives the inbound message from TR to set the power correctly, but the outbound message from the kickr to TR is dropped (wifi noisy training area?) so even though the kickr adjusted correctly TR remains blissfully unaware
Having typed that outâŚpower smoothing might be irrelevant to this - the above failure type could happen either way, although the logic of the kickrâs power smoothing might make it more likely

thats an email to support@ for the answer.
Also, a friendly reminder that friends tell friends to use the Wahoo app to turn off erg mode power smoothing

Friends donât actually give a rats arse about Wahoo power. My only âreportedâ dataset that matters is the Quarq on my Garmin Connect.
I raised this question because I was curious if others had seen it before.
May your legs be smooth, and your power be spikey:
^ thatâs the ârealâ data from the workout. Quarq only.

Wahoo power 
Iâve had some intervals delayed due to radio interference, but that looks like radio interference on reading power from the Kickr. Except for TR continuing to display recovery power for that gap youâve shown, I would have expected zeros but I didnât write any code for TR 
Or simply a display bug on the TR chart.
Only TR support can sort that out.
Hey there! Good question â something does look a lil funky here.
Since it looks like youâre running two power sources, weâd recommend turning PowerMatch back on. That will eliminate the âcompetitionâ between your Quarq and your KICKR, which will probably get rid of these odd power graphs weâre seeing here. If the Quarq is the power source youâre using for the rest of your training, weâd recommend having it connected to TR as well.
Outside of that, it might be a good idea to check your Wahoo Fitness App for any updates that may be available for your KICKR. Additionally, try keeping the trainer unplugged between sessions if you donât do so already â this will help it reset and clear out any bad data âstuckâ inside.
It also looks like youâre on a KICKR Core, which needs to be calibrated every two weeks (per Wahooâs recommendation). You can calibrate your trainer through TRâs Calibration process, or you can do so using your Wahoo app instead.
Hope this helps â feel free to reach back out to me or TR Support if this issue persists!

Thank you! Iâll look at each of these suggestions during the next few workouts.
