As your config file doesn't provide an override, it will store the data in Jaap |

Although interesting, this is for later analysis. You are looking for a _raw.csv file in that same directory. That is a recording with the raw pulses. |

Ok I don't know what I am doing wrong but I get no _raw.csv. I get only three files .fit , .tcx and the rowingData.csv. The only output I see is from journalctl -u openrowingmonitor... see attached file Any Idea what I can check to get the raw output files. MaDe |

You need to put the 'createRawDataFiles: true,' inside the first group of brackets. And remove the header, as 'use strict' is now forced twice. I also see a lot of warnings in the logs about a too slow flywheel, which can cause the behaviour you are struggling with. What kind of Concept2 machine is it, and what electronics is involved? |

Hi,
I think I'll take another closer look at @romanseidl setup and test it next time. MaDe |

The last points obscure the view a bit, but it looks like three distinct curves. So you might have to do something with the electronics, and check if the debounce filter is sufficient. These are the settings you might need to add between the first brackets: gpioPollingInterval: 5,
gpioTriggeredFlank: 'Down',
gpioMinimumPulseLength: 200, |

Hi, so I had a little more time to test it. It's still far from perfect, but it's getting close to what my PM2 monitor shows. 
What I also noticed is that when I set Heartbeat to Broadcast on my watch and configure BLE in config.js, I get this error: MaDe |

What the curve shows is far from healthy for a C2, even the older ones. We have calibration data on file (see the C2 Model C calibration set) that shows totally different behaviour. From my experience, you'd need to see about a 100 to 150 datapoints per stroke on a C2 Model C, where a decent wave pattern is visible. What you would expect is something like this (with a bit more datapoints per stroke):
This kind of wild behaviour suggests that signals are dropped or magnets are not present. |

Thanks for your reply. So if I play the *.csv file as described here: MaDe |

The replay functionality is intended to replay a .csv file and see how OpenRowingMonitor reacts. That saves a lot of work in testing both the app and its configuration. You can get a similar plot by just importing the .csv in excel, like you did. But the key issue is that I would expect a drive (i.e. values getting smaller) of about 50 to 60 datapoints, and a recovery (i.e. values getting bigger) of about 100 to 150 datapoints. It shouldn't be as flat as it is now. Some trend should be visible in the graph. It could be that the power in the stroje is too low to get a trend clearly visible, but then the spikes are unexpected. |

Good day,
just setup the ORM.
I noticed that ORM counts two strokes for each move. So one back and forth is two strokes. So I decided to check this guide:
https://github.com/JaapvanEkris/openrowingmonitor/blob/main/docs/rower_settings.md#checking-signal-and-measurement-qualityThis is my config.js:
But where are the files stored? In /opt/openrowingmonitor/recordings/?
Thank you for your help.
