Feature request: power meter auto zero on connection

Not planned

    (Not been around much), but I suspect this is tricky. Different devices need to be in different positions (based on my limited firsthand experience) for calibration (really zero offset) to work. My Stages left crank needs to be in the 6 o'clock position or it will refuse the command. With so many different options and models, it seems to me like doing this manually is probably your best bet to ensure reasonable accuracy...

    A work around would be a pop-up prompt which when the Power meter connects, asks "Calibrate power meter?" Proceed/No.
    When the user receives the prompt, they can correctly position the power meter, before clicking proceed.

    It would be good to have a pop-up like this, because it takes time to cycle through the menus to perform the calibration. And I never remember until i am about to start riding, after selecting the profile.

    @all. Thanks for sharing your thoughts on the feature request.

    To be straight forward, currently, we do not have this feature where the Karoo automatically sends a calibration command. However, as you would know you can calibrate your power meter on the Karoo. 

    I will take this to our Product team. We will certainly work hard to improve our product but I can not commit on the timeframe when this feature will be available.

    @Dough: For the Stage power meter to calibrate, the crankset has to be placed vertically or straight up and down, with no weight on the pedals and the bike in a stable position.

    I know HOW to do the Stages, I was explaining that having it just try automatically would likely fail in cases where the crank isn't already correctly positioned, leading one to have to try manually anyway...

     

    @Steve: I think if you want this to really be correct, you should ride a bit first before doing it anyway. At least that's what the coach I had a few years ago recommends. If you're taking your bike from inside to out (or vice versa) or out of a hot car and into cooler air, an initial zero-offset before the crank has time to normalize is going to be off anyway...

    @Abhishek - it will definately be a useful feature. That or some quick way of sending the calibration command from a selected profile. From what doug says, a "recalibrate" option on the profile would be good.

    @Doug - that i didn't know. I'll have to check how the zero calibration changes over time - or over a 10 minutes from setting off from home.

    @All - going further - if the head unit detects a major temperature change, it could even prompt the user to perform a recalibration. You have the hardware! :-)

    I'd also appreciate a calibration reminder when a power meter is connected. :)
