Tried it last night and it worked great. Do you intend to at least give the option to pay for ad removal?

I’m paying TrainerDay $3.99 per month that I’d gladly give to you. Of course, I’d rather do a one time purchase.

Just used now https://flux-three.vercel.app/ for my workout in browser and i was really impressed how it work, thans for sharing the link.
Going to start to use it for sure because i never got used to Golden Cheetah. it´s a great visual solution to use with Garmin watch and have all the Garmin stats like load and traning effect

@Cassidyks yes, in app purchase is actually in the todo list. It’s actually been on the ToDo List for really quite some time already. The whole paperwork on getting the account set up w/ the proper Tax documentation is really quite confusing for me hence the delay.

But i am working on it. Until then, the app is on a “freemium” type model. Fully ad-supported.

if you have any other questions / queries and such, you can direct it to the BreakAway thread.

The best and cleanest ANT+ FE-C app for my workouts and plans is ICW (Android only, I think). Flawlessly imports .ERG files.
Too bad is no longer developed / supported though (with newer Android OS, some features are missing… backups etc.)

Tried Flux Three Vercel now. Meh. Works sometimes. Then AWOL, nada. :frowning:
Imho, not quite ready for prime time yet…

You can provide feedback to the developer such that he can address the issues you’re seeing.

Hey @ZeeZeeTop, the developer of Flux here. While some of the features like ANT+ connectivity are experimental the core of the app is pretty stable, I’ve been training with the web app for the last 2 years. Let me know if I can help with something!

Hi. Thank you for responding.

  1. Using Windows 10 computer. Chrome browser bc Firefox doesn’t work. Elite Direto smart trainer broadcasting bluetooth and ant+. Sometimes the Flux app sporadically recognizes the power, controllable and cadence transmitters, then sometimes nothing, nada. Even after closing the app and ride. Note bike room setup is very small, and works fine with Zwift, BigRingVR, TrainerRoad…

Tried the app on Chrome on an iPhone, but it never can connect to the Elite Smart trainer to begin with.

  1. Additionally, when it sometimes does connect with the Windows computer, the Flux only lets me use one of the pre-programmed, dozen or so workouts (eg. Pasta). I cannot get the app to load one of my workouts (downloaded from Intervals.icu). Whether I use the fit. or ZWO file format.
    It will ask to search and find the workout, but once I cluck on the file, it seems to recognize it but loops back to asking to find a file to load again, and again, in an endless loop. It will never load it alongside (or under, or above) the dozen or so pre-programmed files.

Hey, thanks!
Always nice to get some feedback.

Browser support

Ah, yes for Windows you will need Chrome or Edge and iOS is not supported at all. Firefox and Safari just do not have support for the latest web technologies. The first is basically dead, and the second is being restricted by Apple for reasons of … well, not competing with the App Store. Thus on iOS Safari is the only allowed browser, and even Chrome for iOS is just Safari with a Chrome skin.

Anyway I would have to think for a more clear way to communicate this to end Users. Else I am working on a native iOS and Watch apps, so the gap for iOS should be closed soon.

Here is the browser compatibility table from the project page:

Finding devices

  1. It could be some other app that is hijacking the connection, you probably know about this risk but let’s check it out. Zwift is particularly aggressive, even after you disable the controllable connection it still tries to open one.

  2. If you want to use it concurrently with Zwift, RGT, etc, here is a guide on how to do that: How-To: Using Flux and another app concurrently.

  3. Web-bluetooth can have relatively short search timeout, unfortunately the search window stays open for a bit longer even after it gave up searching. I can suggest trying one more time if it does not find anything in a few seconds. Clicking anywhere on the screen outside of the search box will stop search. Reloading the app won’t do anything. Try just with the search window.

  4. A bug with web-bluetooth on Windows. I am using Mac, Android and Ubuntu on a daily bases, which means Windows doesn’t get checked for issues so often. I will need to run some tests to rule out this possibility.

Workout import

Flux supports only ZWO files, .FIT workout files are NOT supported and probably won’t be. I’ve just tested with ZWO workouts exported from Zwift, TrainerDay, and TP. They all work. Can you please share the file or the contents of one of the ZWO workouts that fail to import. Maybe intervals.icu is using some ZWO syntax that I have missed.

Dear @dmarinov

I used an Android phone, AND used the ZWO personally-loaded workout file. Worked like a charm! Simple and sweet.

Will stick with this setup for now.

Many thanks for the elaborate response and helpful suggestions.

All the best,
Zee

I used this again just this weekend. During a custom format zwift race (almost all down hill into the Jungle) I disconnected Zwift Controllable and used Flux to tell my trainer I was on a 1.5% uphill grade so I could push more watts instead of spinning out and it worked great!

Was going to recommend BreakAway, but it seems you guys are here! Good work on the app, hope you can keep improving it!

Yes… Yes… TQ for your kind words. I do hope you like it and am using it…
There are more improvements in the works for it as well. Now I’m experimenting w/ Apple Watch integration.

Has anyone tested this on an Amazon Echo Show?
I’m thinking of getting one as alarm clock with Home Assistant dashboards and such,
and given that I’m on an iPhone/iPad and don’t really want to use my linux laptop for
training I figured, the Silk browser on those Amazon devices would maybe be compatible?

Hi Marinov,

Just got a new computer with Windows 11.
Flux connects to the bluetooth cadence and speed dongle, and my Garmin Dual bluetooth/ant HRM strap.
however, it cannot find my Elite Direto Smart trainer with Windows 11.
(Note - Flux app did find and easily pair and work with my android phone for the Direto smart trainer).
So is Windows 11 not supported still?

Many thanks

For free try https://flux-web.vercel.app/ in Chrome Browser. Firefox don’t Support all needed…
Download your workout from intervalls and add it on the page.

Just tested this web app and it’s absolutely remarkable. Works like a charm out of the box, no setup needed. Thank you!
