There may be something there with mobile vs desktop depending on your phone. I had the same problem with an old vs a new laptop. I tried to use my 2010 vintage macbook as a dedicated TR machine but I was getting painfully erratic power fluctuations, long delays on dropping power at the end of intervals and just generally a terrible experience. Using all the same sensors on my more current macbook and all those issues just went away and it works really well. I suspect powermatch may be computationally expensive and on older/slower/overwhelmed hardware it may end up lagging behind.
Using a galaxy S8 and a 2013 Macbook so that might be possible.
One other thing to note is i used ANT+ only on my phone ramp test but for the 2nd iOS Macbook test i had bluetooth and ANT+ for the trainer and the UNO.
Going to run some SS tonight with the Macbook, ANT+ only to see how it looks. May have a look at sensitivity aswell.
Tested a couple things tonight (results below). Concluded that in my case the difference is marginal and doesn’t impact the overall quality of my sessions. Both intervals felt similar in terms of intensity. Much the same conclusion as the TR thread the explains powermatch…
Session completed on my Macbook.
Block 1 - ANT+ only. Favero UNO and Bkool pro 2. Powermatch (new)
Block 2 - Put bluetooth on. Seemed much the same as ANT+ only
Block 3 - Disconnected and reconnected all ANT+ and bluetooth devices and it looks like it defaulted to the bkool with no power match but power match was on.
Not entirely sure why the second interval resorted to the bkool only even when both devices were connected.
I did try bluetooth only but that didn’t work as i hadn’t enabled the double power function in the UNO settings. Will give that a bash.
Wondering what y’all’s experience has been with the new powermatch and your ramp tests.
I have been using the regular ERG without powermatch with a 2018 kickr for most of my training and more recent ramp tests, but I switched to powermatch for my more recent rides and my latest ramp test. I have been training pretty consistently (and feeling good), and went from 312 (ERG) → 325 (ERG powermatch). Of course I’m second-guessing the result because I have read that wahoo kickrs can be off by 10 W. I calibrated my powermeter (new force quarq) and did a spin-down before the test.

I feel like @Jonathan would be telling me to trust that I am getting stronger, and not assume the negative possibility… 
Hey, all! Just dropping a note on this thread to help us move forward with making sure athletes are getting the best experience with past/present/future versions of Power Match. If something seems amiss with Power Match, we’ll have athletes get in touch with support from now on so that we can more effectively manage reports of device-related issues.
You can email the Support Team at support@trainerroad.com, or submit a request online with Power Match issues or inconsistencies.
Thanks to you all for doing your part in helping us constantly improve! 
I tried it today on a ramp test. It felt fine at very low wattages, but it seemed like once I got up to higher wattages it was impossible to hit the power targets. Usually I find on ramp tests in pure erg mode I end when I simply can’t push the pedals anymore and my cadence drops. This time I found my cadence was where/if not higher than where I expected it, but didn’t feel that same heavy trainer resistance in those last few steps. It was my first time trying it out, using a kickr core and vector 3s. Perhaps I am just not used to it yet or need to adjust the sensitivity.
Sounds similar to what I’ve been experiencing on the desktop app (using a Saris H1 and Assioma Duo power meter). Initially, the beta version of EPM felt great - a noticeable improvement over the previous PowerMatch. However, something seemed to change following an update to the TR desktop app. It was OK on low and mid-range power but higher efforts didn’t produce the same level of resistance that the beta version of EPM did and/or there was a bit of lag going up to higher wattages. Consequently, I found it harder to hit my targets.
Following a suggestion somewhere on this thread I increased the slider scale setting on setting one to one. This made a bit of difference but was still not as good as the beta version. In the end, I went back to using the legacy version of EPM. Not perfect but better than EPM.
There’s just been another update to the TR desktop app, so I’ll try EPM again to see if it’s any different.
Any thoughts @IvyAudrain?
I’m experiencing some odd things with powermatch too on the Android app. I’ve contacted support
@All
Considered, we only tested the desktop version in this thread, the new Powermatch was only available in this one!
new Powermatch is not yet available in Android and i don’t know how it is handled on iOS Beta!
Sorry for the trouble, its hard for us to tell here exactly what’s going on without seeing your internal ride log, so I think the best move here is to email support@trainerroad.com, so they can take a closer look at that data, walk you through any troubleshooting or firmware updates, and see exactly what’s amiss.
Cheers. I tried it on Mary Austin -1 today with the advance setting slider set at 1 and it seemed to be a bit better, though there was a slight lag at the start of some of the intervals after the recovery periods.
I’ve had more than one kickr and haven’t found the power to be out of line with my power meters. There are known issues with overheating, but generally it’s been within the margin of error. I have noticed that I can see drivetrain losses, recently lubricated my chain and gained 7 watts… the pm and the kickr power are back in line. Bike has been on the trainer too long me thinks.
Hi everyone, I just ordered the Assioma Duo pedals, and was wondering how well the powermatch works with the Tacx Flow Smart (or the Vortex, which is almost identical)?
I ordered the assiomas to get more accurate power numbers on my indoor and outdoor workouts, but reading some comments in this thread, now I’m afraid the indoor workout experience might not be very good.
I have the Garmin Vector 3 single side and use them with a Tacx Flow Smart. I don’t have anything to compare it to, but in general it works well. The power fluctuates a lot more than when using just the Tacx, but from what I have read, this is a better reflection of reality. Tacx on its own shows a higher W than with the powermeter as well.
VO2 max intervals require some help from shifting gears to get sufficient resistence, and often I have to shfit down to my lowest gear to get sufficiently low resistance for the recovery intervals. I figured it was likely to be down to using a low end smart trainer rather than software, but haven’t been able to try the new Power Match to be able to tell how much of an improvement it makes.
Hi there, is the TrainerRoad Team still collecting data from the ride reports? I have been submitting my feedback and am happy to continue doing so as long as it’s still helpful for refining the ERG mode PowerMatch. I feel that my experiences with PM have significantly improved over time and I am looking forward to future tweaks that will make it even better! Thanks for all the hard work that’s gone into this.
Thanks for submitting your reports! No need to continue if things are working well. If you do end up having issues you’d like help with, support is the best place to go. They will be able to diagnose and resolve PowerMatch or device problems at an individual level much better.
Did Whorl earlier this week no problem. Today it’s plagued. Going into one of the intervals where power ramps up it kept ramping up longer until I paused the ride. Then resumed and power fell to 50%. Paused again and resumed and all was good.
Then on the ramp down for same interval it kept ramping down longer. Had to pause resume pause resume again. Next interval same crap
I’ll send to support but anyone else have this? Nothing in my setup changed.
I jumped into the same workout after I got done and jumped ahead to the ramp up and down, no issues on the second go, not sure what happened above but seems isolated
I didn’t even know that the new facility existed. Tried it to day with my 2017 Kickr, Stages Left, and the slider set to .75.
Ever since I’ve had my Kickr, TR Powermatch always caused me to miss the interval targets by a couple of watts. In the big scheme, that’s meaningless. But to me, it is mentally difficult to ‘miss’ a target and I’ve always hated this.
My first ride with the new facility was a revelation! I still got the gentle ramp up and overshoot, but then it settled right into the target wattage and stayed pretty close. Every work interval ended up a couple of watts higher than target. (Again, meaningless…but mentally satisfying.) I’ll chime back in this week to report with more data than a single workout.
Update: I’m still happy.
- Very short intervals (30 seconds) perform better than the original. The behavior is a smooth, fast ramp up followed by an overshoot. Then it settles down and bounces slightly high and low until the end. Typical result is hitting the target average wattage.
- Long intervals - same
- One-minute intervals, 115% ftp - These had the typical ramp, overshoot, and settle behavior. However, PM seems to undershoot a bit and I missed every interval by 3 watts. My guess is that the variances are more pronounced at higher wattage levels and 1 minute is too short for it to average out perfectly.
For those who have been using this new PM feature, what does the slider actually do? Based on feedback from earlier posts, I settled on ‘75’ but have no idea what happens if I make changes.
This is such an improvement over the original PM functionality!
Follow up question: I’m using a Stages left power meter so I know that the variability will be higher than with other measuring point options. What is the impact of the power smoothing option (1-sec, 3 sec…) on the PM feature, if any?
