Rowing App for Waterrower

darkmephisto
over 5 years ago

I think that a lot of people are serching for a witged / datafield / app to record her training on garmin connect.

This was not possible because the Rower had no bluetooth module. But now there is such a module and it would be a phantastic thing if there would be a IQ App to record the rowing activity on the Watch. I think this could be a good Idea for a developer to make such app to get some money because there is nothing in this direction on the market.

What do you think?

    Great stuff. Thanks for sharing. But where does the power data come from? I thought the S4 is not capable of recording that? Hence third party offers like the SmartRow device?!

    Thanks

    S4 extrapolates power based on the water level you tell it that you filled the tub with.   Its a rough estimate based on speed + water.   Not a true loadcell calc.   So its likely close, or at least consistent if offset from the real number.

    And, the S4 transmits distance traveled on the recovery (glide) but I don't think the Smart Row does.


    You might be able to further "calibrate" by changing the water level value in the monitor so that your average power over a known maximum effort distance with similar cadence matches between the waterrower and a more accurate ERG such as a C2 rower?

    Do you happen to sell & ship those pre configured to Germany? :D

    Thanks! But the S4 itself doesn't display the metric? Do I enter the water level somewhere. Couldn't find it :-(

    In the options, somewhere in the menu you can add in how many L or what line you filled the water too.   and the S4 does show watts/power

    Hi,

    I was extremely interested in finding this project.  You have done *exactly* what I have been considered doing myself.  I am busy getting a Pi Zero W together but I have a couple questions before I buy the more expensive upgrade to our old WaterRower.

    We currently do not have an S4 monitor.  If I am going to upgrade the WaterRower, I will get a SmartRow only, so no S4.  I have seen comments that the code doesn't work without an S4.  Is that still the case?  From a cursory look at the main module, it seems like it should work without the S4 input but I have not dug into the code anymore than that.

    I plan to use BLE to talk to the SmartRow and ANT+ to talk to our Garmins (945 and Vivoactive 3).  Do I still need a second external Bluetooth module if I only plan to use one BT connection?

    Is this the best forum to talk about the project?

    It looks like the code will work without the S4 monitor.  I was able to record a workout with my FR945 via ANT+ by modifying the code a little to send fake rower data via ANT+.

    Next step would be to get the actual SmartRow upgrade.  So far I'm only $16 into the project (I got the screen because I thought it looked cool :) )

    I was unable to pair a Vivoactive 3 to the Pi.  It looks like it does not support the ANT+ fitness equipment profile, which is a shame.

    Thanks for sharing the project!

    I got everything going with my FR945 via ANT+ and new SmartRow, using the Raspberry Pi project with some modifications.  I do not have an S4 monitor, so that is definitely not necessary.

    The FR945 (V8.20) captures distance (meters), power, stroke count, stroke rate, distance / stroke, and pace / 500m.  This gets displayed in Garmin Connect (app and website), and most fields can also be displayed in real time on the watch.

    Wow, this is very interesting and exactly what I am looking for. I am about to buy a waterrower and use my fenix 7 for all my sports activities. Unfortunately, I have absolutely no glue about raspberry and programming it.

    Is there any way that some specialist on this could help me?
