how to run GUI from Linux CLI

[ham-smart]

hi, I just installed app to my raspberry pi and I want to start GUI. So I just tried follow setcap command, restarted my machine, but couldn't open GUI. How can I run GUI? just give me any tips. Thanks.

GUI is accessed from a web browser that is on the same machine via localhost. Port is normally 80 or else if you set it to something else. You can check the logs in syslog if the app actually started ok.

What is the version of OpenRowingMonitor you are using? I've updated the install script and libraries yesterday, so it might be something to look at.

What does the GUI does show? Does it start, or is it just the login prompt? And does the webppage Abasz suggested show something?

Small practical tip: look for the comma's. In the config file, the last line of each structure should NOET contain a comma.

ah, I have no access to the actual file right now, but in short, I started from scratch and with the default config.js file, located in config/config.js - I removed the "//" in front of the setting (just to test) :

From this:
// EXAMPLE ROWER CONFIG : using a DKN R-320 Air Rower as is
// rowerSettings: rowerProfiles.DKN_R320

To this:
// EXAMPLE ROWER CONFIG : using a DKN R-320 Air Rower as is
rowerSettings: rowerProfiles.DKN_R320

Not even this works. so I tried to replicate the line and change the rower profile.

// EXAMPLE ROWER CONFIG : using a DKN R-320 Air Rower as is
// rowerSettings: rowerProfiles.DKN_R320
rowerSettings: rowerProfiles.Sportstech_WRX700

But had no luck. And it seems to fallback to Default anyways.
I tried to change the fallback in default.config.js - just to try, and that ended up with no web-browser startup :p

So.. only small changes from the original config.js file.
When this did not work, I tride to change values under config/rowerProfiles.js - the same way. I left the original with "//" in front, and replicated the setting under, like with the rowerSettings over - what did the trick. Even tho it is a bit of tweaking, I can work from here to test it, But I really want to create a new profile with the TrainX WaterRower pro, instead of changing DEFAULTS, but I cant get it to work

I can always get back to the original working model, but not change the profile setting.
So.. can you try to change your profile to another and actually check if it change the profile?

I am pretty sure that your config file is incorrectly formed and that is why it does not get picked up. We need to hole file to verify this, not just samples, but the hole file. I am like 99% sure that you are missing a coma at the end as it is not in the commented out line in the example.

I'm slowly convinced we need to add a name to the rower profiles and have the config manager report what is loaded. The current merge process fails unnoticed and it sucks.

Similar to @Abasz , but his solution contains objects that are not in the release branch yet.

[Abasz]

I don't think the comma is a Syntax error there. Trailing commas are allowed in the syntax for JS objects

[Raymond-ArrA]

I am going to try this later and get back to you. Guess I'll Just go for a fresh install, both OS and opemrowingmonitor, to ensure that there is no faults from start

[Raymond-ArrA]

Finally.. I dont know what was the Deal. Fresh install os, fresh install openrowingmonitor, and then Just wrote a New line with rowerSettings: ...

Now I got the wrx700 profile, ant this really seems to be more of a something like my TrainX WaterRower pro machine.

None of these rowers are correct, but one computer told me I was olympic master, and one told me I was a noobish 90 year old. Differences in 10 kmh takes the breath of everyone 😅

now my 10 Pulls reporter 9, and time, distance, etc were actually looking like something. But.

10 Pulls (says 9)
52 meters
3:38/500m
Drive 0.66m
Drive 0.95 sec
Recovery 1.24 sec
27 strokes pr. Min

These looks something like ok.
But watt is calculate to 34 w..
Is that correct? 🤔 Maybe I am a noobish 90 y/o 😅
But.. Is there some values to correct it, If it is wrong?

[Abasz]

watt will depend on the inertia and drag, that is probably completely different-. Please have a look at the readme it explains this. There is a discussion on how to measure inertia as well.

[Raymond-ArrA]

Okay, thanks. I will read more 😅. I love this project. The only rowing monitor that May complete with concept2 that I have found.. Mostly because I need to tweak these options.. Thanks a lot 🙏

[Raymond-ArrA]

The dragFactor on the WaterRower is set to 32000.. Can you explain the values accepted, when default is 1500? The gap between looks dramatically high, though I really still thinknthere is something that is not right.. Could it be that 32000 is a number too high, so the system falls back to another value? I don't know, but I really dont get it.. something has obviousely changed, but still I am rowing on a watt level between 20 and 40 watt.. And it takes me almost 50 strokes to get 200 meters.. What doesnt sound right to me 😅

[Raymond-ArrA]

It might also be inertia.. 🤔 But looking to understand them both 😅

[Gordon-Shumway2]

Dragfactors of around 30000 are normal for water-based rowers. My FDF neon pro V with a water tank volume of 17 liter has a drag factor of 31500 and an intertia of 0.74.

It might help if you

• stated which rower you are actually using (you mentioned "TrainX WaterRower pro" but googling that returns no hits)
• uploaded your config.js and rowerprofiles.js
• would turn on debugging,
• add/modify "autoAdjustDragFactor: true,", restart the ORM service, do ten to twenty strokes with some effort (but not full force) and upload the .tcx file for that session.

Cheers,
Michael

Right now I dont even find it myself. Look up masterfit w rower 400. Identical rower as far as I can see.

I am trying your way as soon as I can..
