    I am trying to switch from Zwift to The Sufferfest (TSF), but this is a feature I've always used in Zwift and would really like to see it in the app. There is about a 10-12 watt difference between my crank based RotoR power meter and the Tacx smart trainer I have. I'd need to manually play with my FTP or 4dp values to match power output for outdoor rides.

    The compelling feature for me to come to TSF is that outdoor rides are a first class citizen as opposed to TrainerRoad.

    Posting a comment here to be notified when this feature is in the app.

    If you have a KICKR you can backdoor a power match feature. In the Wahoo Fitness app, select your Kickr, then enable "Control w/ANT+ Power meter" option and then select the ANT+ ID for your on-bike power meter. In this way, I'm able to use my QUARQ power meter to provide power data feedback to the Kickr. Works great and seems to have the same end result as using power matching directly via the app (the way it works in Trainerroad, for example).

    Ok-I have a SNAP.  But this won't work unless you have an ANT key for your phone, right? What if you're using a laptop w/ant key?  How would you do this?  (Can't believe it's taken them this long to implement something that other platforms have now had for years).

    I am using a PC-laptop with an ANT dongle and no ANT key for the phone. The step by step for me to get this to work with my KICKR was as follows

    1) Enable bluetooth on your phone and open up the Wahoo Fitness App

    2) Find your KICKR inside the Sensors menu, select it.

    3) Enable the "Control w/ANT+ Power Meter" option. Be sure that you enter your ANT+ ID from your on-bike power meter

    4) Do a spindown (not sure if this really matters, but it can't hurt)

    5) Inside the Sufferfest app, use the KICKR as the power data source and use your power meter as the cadence source only. Note that if you select your power meter as the power source it breaks the workaround

    In reality now, your power meter will provide the feedback loop to the KICKR (outside of the SF app), but the SF app will "talk" to the Kickr to give power targets. The Kickr will also report power (as measured by your power meter) back to SF app.

    Sorry I can't provide SNAP trainer specific info, but the general process hopefully is applicable to other models.

    On an ongoing basis, you do not need to have the Wahoo Fitness app open on your phone (and in fact, I'd recommend not having it active at all to avoid any possibility for 2 apps trying to control the Kickr at the same time)

    Tried the above on the kickr but didn't work.  Frustrating that sufferfest has yet to implement this feature. Been using sufferfest for 4 yrs.  Will get rid of my inaccurate kickr or finally move to another platform.

    I would really appreciate not having to play with my intensity numbers to have an accurate workout. It’s quite annoying to not have power matching. It’s one of the only things that keeps me using Zwift as well
