Disabling native power

Karchevsky K

На які показники впливає власна потужність і чи будуть відповідні дані скомпрометовані, якщо я вимкну власну потужність Garmin і використаю бігову потужність Stryd?

    thanks for all this. I already new most of it as I've used Garmin for tooo long. I ended up resetting the watch and redesigning all the screens - i.e., deleting all and any adjustments that I had made to the Garmin system. I should have done this much earlier. I have reset this Garmin 955 way too many times in the past. It's getting so I can systematically go through each screen in like 5 minutes, I've re-set this watch soooo many times. I like screens with max number of numbers on them. I need to reset for both bicycling and running. I do like the new Garmin screens that I can put 10 numbers on. The problem yesterday was that I was just absolutely not seeing any power. The watched stopped using power from STRYD sensors in the middle of a run and I could not adjust them to get them to work, at all. I'm spending way too much time on getting Garmin products to work. I'm glad I have a Lezyne bike computer on the bike so when Garmin watch fails on the road, I have a record of my ride! The inconvenience is that now I'm following training plans that are compatible with Garmin, I need to look at my watch all the time. I could get a Garmin bike computer, but then when Garmin SYSTEM fails one way or another, I'd have no record of my bike ride. Stryd is a good backup for my runs and Lezyne is a back up for my rides.

    Ok, so you know that setting Garmin power to "external" absolutely does not use Stryd, right? Contrary to what you said in the previous comment and what you implied the latest one? The built-in running features of the watch never use power from Stryd. You always need to use some sort of third party app/data field in order to use your Stryd with your Garmin.

    And you know that you need to use the Stryd Zones data field in order to see power from Stryd? Because you didn't mention that before. If you were already using the Stryd Zones data field, then it doesn't really make sense to try to set Garmin power to "external" in order to use Stryd power, because you should realize that Stryd Zones doesn't care about the Garmin power setting.

    Hopefully you also realize that the built-in Garmin workout feature won't work with stryd, you'll need to use the Stryd Workouts app for that.

    I'm not sure how resetting your garmin would help your situation, but I'm glad it seems to be working for you now.

    FWIW - I have been using Stryd with various Garmin's since Stryd launch in 2017.  For a watch like the 945/955 or 965 like I use that supports "native power" the appropriate settings are Running Power = "on" and set to "Accessory Only" and (most importantly) installing the Stryd Zones data field.

    This will cause the Garmin native power while in-activity to always show as 0 and you'll need to view the Stryd Zones DF to see power (and follow non-Garmin-input training workouts).  This works great for me and I test this with 2 power-based workouts a week and run "by power" on all runs.

    Now, this is the odd part - despite those settings above, and the fact I always show 0 for Garmin's inherent datafields, the watch does apparently capture run power because it gives me a Power # for my Lactate Threshold level (along with Pace and HR).  This is NOT Stryd's "power" because it's inflated by about 140-150%.  So there is some capturing of the power numbers, but I honestly don't know what they're doing with it other than this Lactate Threshold.

    I am long "over" Garmin and their stupid @#$%^ stubborness in not allowing 3rd party power meters like Stryd, but I remain hopeful that one day they will wake up and make a change.

    Sorry, I have to disagree. You are the second person in this thread to say that when you use Stryd, you turn on native garmin power and set it to “accessory only” (or as the other poster referred to it, external source). 

    I just don’t see why you wouldn’t turn off Garmin power completely, like I do. People literally asked for this capability as soon as Garmin introduced native power from wrist, because Garmin power conflicts with Stryd power for third party services such as Strava and Training Peaks, which prioritize Garmin power. Now that Garmin has added this capability, people are purposely leaving Garmin power enabled?

    When you turn off Garmin power completely, you avoid recording Garmin power (even if it’s 0) to the FIT file. I realize this may not be an issue if you only ever analyze power in the Stryd app. I prefer to see the same power in Strava and the Stryd app, although tbh I don’t really care about power that much. (I got my stryd for free and I really only use it as a footpod). But given that Strava uses power for certain analytics, I prefer to it uses Stryd power.

    The only advantage I can see of leaving Garmin power enabled is if you want to compare Garmin power with Stryd power (and again, you only ever look at power in the Stryd app.) I don’t see any point is recording 0s for Garmin power all the time.

    Anyway, whatever works for you, but I don’t understand the reasoning behind leaving Garmin power enabled when you want to use Stryd. The Stryd DF and Stryd phone app / Stryd powercenter don’t use Garmin power either way (and Garmin power can’t use Stryd as a source), so it’s kind of a mystery to me.

    Also, does Garmin really record zeros to the FIT file when you turn on power but set it to accessory only (and you don’t use an accessory such as RD Pod or.a compatible chest strap)? Or does it record no data? I would’ve expected it to record no data, but I haven’t tried it lately. If it records no data, then there should be very little (or no difference) between “off” and “on / accessory only” except maybe for the one quirk you pointed out.

    Note I use several 3rd party apps (strava, sporttracks, runalyze, etc) and I have no issues with it reading the correct power.  In fact, as I said in my post, Garmin power doesn't even show up in Garmin Connect for the activity itself.  

    Maybe you've never tried "accessory only" option?  It doesn't sound like you're familiar with it.  IIRC this is the setting that Stryd developers recommend themselves.

    That’s because you’re not connecting to an accessory that provides Garmin power (compatible Garmin chest strap or running dynamic pod). Effectively, your setting of “power = on / accessory only” should be no different than “power = off”.

    I am familiar with it — I’ve tried it in the past. “Accessory only” means that native power will come from a *Garmin accessory that supports running power* (again, compatible Garmin chest strap or running dynamic pod.) It does not mean that native power will come from Stryd (seems that you understand that.)

    I don’t understand why Stryd developers would recommend this.

    It seems that in your case, you’re not running with an RD-pod or a Garmin chest strap that supports power. If you did, you would definitely see Garmin power in your activity.

    If you choose “power = on / accessory only” and you don’t have a Garmin accessory, then it should be no different than “power = off”.

    Could you explain the rationale behind selecting “accessory only”? I mean other than “Stryd devs said so”.

    The other poster said that they selected accessory only (or “external source” as they put it) because they believed that’s what’s necessary to use Stryd. Clearly this is not the case. Stryd could be used with Garmin (as long as you installed the stryd data field) before Garmin supported native running power, and it can be used whether native running power is enabled or not. 

    EDIT: I record stryd power on every run and I always have garmin native power turned off. I’m interested to hear what you think would work differently if I changed it to “on / accessory only”. I see Stryd power in Connect (as a 3rd party IQ field), Strava and the Stryd app just fine.

    EDIT2: I just tried “power = on / accessory only” in the following scenarios:

    - no sensors connected: native run power field displays “—“. as expected

    - HRM-PRO (only) connected: native run power field displays “0” (I’m standing still). as expected (HRM-PRO supports garmin running power)

    - Stryd (only) connected (natively as a cycling power meter *): native run power field displays “—“

    (* obviously I don’t expect this to work, but there’s no other way to natively get power from Stryd. I also had the stryd zones DF installed, which did detect the stryd and display power, but clearly I wouldn’t expect that to affect native power, knowing what I do about CIQ apps. I literally wrote a CIQ data field that displays power from stryd.)

    Obviously when “power = off”, the native run power field is always “—“.

    Pretty much what i expected. When I have stryd (only) connected, then there’s no difference between “power = off” and “power = on / accessory only”.

    So I’m still mystified as to why “power = on / accessory only” is the recommended setting for Stryd usage. Especially since this could cause problems for people who choose to run with a Garmin chest strap that supports run power.

    You should try actually running with a garmin accessory that supports garmin running power, such as the HRM-RUN or HRM-PRO straps. You’d discover that “power = on / accessory only” might not be the setting you want. For example, Garmin power would be recorded to your FIT file, and it would override Stryd power on some platforms, such as Strava. (At least it did in the past. I don’t see why this would’ve changed — Garmin power is a native field, Stryd power is a developer field, and it makes sense for 3rd-party sites/apps to prioritize native data, all things being equal. Same as it makes sense for Stryd to prioritize their own data.)

    I mean they want you to buy their chest strap or running dynamics pod. I don’t like it either, but I get it.

    Then again there’s also the fact that the Garmin running power algorithm and the Stryd algorithm produce different numbers. (Same with any other 3rd party running pod.) Unlike cycling power, running power isn’t something that’s directly measured and has consistent results across brands.

    Plus, now that they support power from the wrist, they probably don’t care about external power as much anymore. Same as the ubiquity of wrist optical HR means that most people don’t want to wear a chest strap, in most circumstances. You don’t see Apple releasing a chest strap for Apple Watch Ultra.

    Who knows, maybe they will discontinue the RD-Pod eventually, same as they discontinued Garmin footpods.
