Water rower - can't get the settings to count strokes

[silentcossack]

Hi folks,

I used to have a magnetic rower and was using open rowing monitor just fine, things worked great. Now i've moved to a water rower and I can't get it to count the strokes properly. It's either nothing or too many. I've tried a million things, but wanted to start from the beginning here. I'm using WRX700 as the profile as I feel that matches my rower pretty well (in terms of type). In this mode, it counts one stroke, then just ignores the rest as per the log below. I do have 2 magnets per revolution. I test the sensor with multimeter and all good. Seems like the filter just ignores the measurements. Complains about acceleration. I tried playing with those values, but still ignores with a different message. Only thing that helps is raising number of errors value to above 0. But then it counts too many strokes, basically counts strokes even when the paddles spin down from inertia. Any help would be greatly appreciated.

I would increase maximumUpwardChange to a much higher value, as that might frustrate stroke detection.

If you get rid of most unneeded corrections, you could increase the flanklength with one, as this tends to stabilise things.

Thanks for replying!

Here's the new config based on your suggestion:

rowerSettings: Object.assign(rowerProfiles.WRX700, { maximumUpwardChange: 3.0, flankLength: 3 })

And here's the log. Unfortunately, not much change that I can see.

You need more room in the noise filter. There are increases in currentDt with a factor of 6 (!) and decreases of factor 0.175. this is quite eratic, and the noise filter sees them as errornous. If you know they are OK (a visual inspection of a graph of the raw data really helps here) than you should modify the settings accordingly.

[silentcossack]

I'm not sure I fully understand what you mean by modify settings accordingly. I take it that you mean increase the upward and lower the downward values. I did that as follows:

rowerSettings: Object.assign(rowerProfiles.WRX700, {
maximumUpwardChange: 7.0,
maximumDownwardChange: 0.1,
flankLength: 3
})

Now it just doesn't log anything after the first stroke while I row and only logs once i stop:

So...after a really long time of messing around, turned out that the reed switch that came with the machine was not working out with the Pi. The switch works, just not how the Pi/ORM expects it to. I put in my own reed switch and magically the out of the box WRX700 profile works beautifully. Just in case anybody comes across a similar issue, try a different reed switch, clearly they make a difference.
