Change profile via GUI for another dumper settings/strava account.

[AlexObukhoff]

I have a NordicTrack RX800 and am planning to set up rpi4 for Open Rowing Monitor.
As I understand it, for each level of complexity, you need to use your own profile. But at the same time, it cannot be switched without editing the configuration file and reloading the software.

If I use the simulator alternately with my wife at different difficulty levels, then problems arise.

Maybe it makes sense to switch the profile to the interface?

Another problem is two Strava accounts.

Hi Alex,

In the current setup that is the case, as some variables vary when setting the new dragfactor. You could try the new version of the Rowing Engine (see https://github.com/JaapvanEkris/openrowingmonitor/tree/Backend_Redesign), which can handle the drag calculation for the RX800 automatically. So the need for changing the drag settings manually has been removed in that version as many of the old settings are calculated automatically for you. We are currently testing that version before it will be promoted to the new version, but it is extremely stable (and less vulnerable to individual settings). When you look at the settings there, you see a much simpeler setup.

I ran a lot of tests with the new engine on the NordicTrack RX800 data (I used to own one myself), and it is very reliable with these settings.

For Strava, I have no solution. But Lars might have.

How to connect NordicTrack RX-800 to RPI 4? Directly wire the red connector to pin 17 and gnd?

I plugged in a dupont cable (standard Raspberry Pi cable) into this connector directly into 17 and GND. It is a simple reed switch, so there are no electrical issues.

In the log, you'll find a report saying

Its all :(

What happens if you restart the service (settings are only effective after a service restart). Please note, most HR measurement devices only become active when somebody sweats on them....

of course it's understandable
By the way, it is convenient to restart the service using the button in the web interface

strap on me, checked on the watch - the pulse shows.

Please note, the reset button in the GUI does not restart the service, it just resets the metrics.

Does the Suunto allow for multiple BLE links at the same time? My Garmin Dual does not (it does allow a simultanous ANT+ and BLE, but not two BLE connections).

Hi Alex,

those are good points. As Jaap already said we are currently working on making the physics model more robust. Ideally this should remove the need to change drag factor manually.

Using multiple Strava accounts is something that I would like to address together with user profiles at some points. I noticed this when working on the arcade-branch: for games we need some user specific information (i.e. FTP) to balance the difficulty of games. Parameters for VO2Max calculation and Strava-Settings are other things that should move into the user profile. So yes, we hear you :-) User profiles will eventually happen when the arcade-stuff is released, but that will definitely happen after the big engine rework.

Yeah, that would als allow for more scenario's, like HR Zones and similar functionality. It is something even Concept2 hasn't adressed yet, which is quite odd when you think of it: you want the monitor to show specific limits during the row. EXR is now experimenting with personalised speeds (i.e. calculating your speed based on your weight). Knowing the person better allows for much more detailed feedback.
