Cycling Watt Power in Locus ( Ant+ BLE or computed)

Hi there,

excellent proposal!

However I believe this needs more structure:

1) is about getting Powersensors/powermeters connected tot he device via ANT+ or BT4.0. Then while tracking is on the power values should be recorded as well and of course there should be an option to sho the current power value in the dashboard as well as avg and max. This all should be straight forward and it were a real enhancement of Locus Pro!

2) is trying to calculate current power values based on various factors. This seems quite complicated and anything else then reliable. It could also be done after excercising by applications like Spoprtstracks, so i would consider this as nice to have

My positive vote is most of all for option 1).

It should be simple enough to add support for power logging, at least for simple version of it.

Also it would be nice if this could be implemented in the live tracking API. Currently I only know of Ipbike which supports power reading with android!

According to this blog post that product doesn't exist yet - http://www.dcrainmaker.com/2015/11/limits-meter-really.html although looks nice.

Happy new year! :)

I am currently thinking about acquiring a power meter for my road bike. Since many years I am using Locus Maps Pro as a bike computer, at the moment together with a Samsung A3 (2017).

Now, if I get a power meter, of course I want a device that shows and records not only the gps data, but also the amount of power (in Watts) I put into the pedals, together with the cadence (aka pedal frequency) and maybe the heart frequency.

After a ride, I want to import the gps data together with the recorded power meter (and heart rate) data to Strava, as easily as possible.

I know that many fellow riders do this with special sports tracking devices or the Strava app. Some of them are mentioned on the following site. It also explains how to get activity data to Strava:

https://support.strava.com/hc/en-us/articles/223297187-How-to-get-your-Activities-to-Strava

I'd like to get this done with only Locus Maps Pro, and not needing e.g. the Strava app or an additional device.

P.S.: Of course, when a recorded track e.g. has to be cut manually at the end (because I forgot to stop recording before entering the train home), both the gps data and the corresponding biometric data must be cut by the track editor simultaneously.

The following image shows additional track data (i.e. besides gps data) of a recorded activity, as it is presented by Strava.

This is a support page of Stages, the manufacturer of the powermeter I just bought for my road bike, listing third party Android apps that are compatible with the powermeter:

Third party apps compatible with the Stages Powermeter

I'd like to see Locus Maps in this list in the not too far future. :)

Things are developing nicely in the cycle power meter area. Have you seen IQSquare? I ordered a pair of these power meters at Indiegogo and expect delivery in Nov 2018 timeframe.

So, Menion, there is still some time until I will hopefully receive my power meters to develop a way to record power measurements in Locus Map together with the GPS track and with HR.

However if there is no such option when I receive the power meters I will be forced to use another app for recording which I would regrett!

Do you see any chance to get something going?

Good day Bernhard,

nice tool, thanks for sharing. We have some serious plans on rework or our Bluetooth system in Locus and power meter should be part of this improvement. 29 votes in this idea is something, we definitely should not ignore. Some time frame? Hope that during Q1/2019, work should start.

This is just to add my vote in favour of powermeter support in Locus. Hope it will be implemented soon

Have banned every cycling computer due to how great Locus maps is. Thanks for such a great tool. But I also would love to see the integration of parameters in the tracking. I don't want to switch to other apps as there is just no better one.

Thanks for thinking about this matter !

This would be a great addition to Locus Maps. Any updates on this?

Yes... Would be nice really, finally to have this feature in the payed app.

Repeating "Lack of time, problems, blabla. " over 3-5y, sorry to say, but these are just excuses.

No problem... if Locus Team doesn't want this feautre, no problem, be honest and close the thread. IMHO

Yes, would be nice to support dual-side powermeters, but it's not a must. If it works only with one side for a while, that is also ok!

So I don't believe it's so hard to add a new source and a data-channel (with number value) to display/track :)

Cheers,

Kris

ps. I hope it will be there in the app very very soon...

I almost bought a power-meter today, because I thought Locus supported this.

Luckily I checked the ANT-settings and found out there is no support for power-meters.

As Locus is by far my favorite bike computer, I cancelled the order of a power meter.

This saved me some money, which is a good thing :-) , but I still would like to see support for a power meter in the future ;-)

Hi,

I love locus map and was using pro version of it for some time when I bought a stages power meter thinking locus would support it. But it didn't.

I have tested other apps on the ant+ page that can record but wasn't satisfied by those.

Finally, I developed my own app for ant+ on android during corona evenings and nights to show and track power data.

I won't put it on play store as I found later there is another app alreasy existing: ghost racer that allows you to collect and save power data in a way my app was doing it.

For android, you can use split screen display on recent versions.

So my tip: use locus map in split screen mode.

I hope there can be power support in locus map though. It is such a good app.

Frederik

Split screen sounds like a great idea Frederik. I wanted to do this with the Strava app, but that does not work. Could you compare the reading with the Wahoo app? I compared the Wahoo app to the locus app for Heart Rate on Bluetooth and Ant+, the Wahoo app is a lot quicker to respond to changes than the locus app.

I absolutely love Locus Map Pro as a cycling computer, no need for an extra device other than the smartphone.

I just bought a 4iiii powermeter. Like others here I was expecting the support of bluetooth powermeter, as cadence, speed, heart rate bt devices worked already well.

So from my side this would be a priority, any implementation would be really appreciated. Powermeters are getting more and more common, so it should be worth the effort!

Best regards, Christian

Please add recording of power meter data into your great app.

Now that Locus 4 is out you should have plenty of capacity to finally implement the power meter? ;)

Would love to switch back from ipbike (which is very good!) to Locus (which I vaguely remember as really great! Has been a long time since I last used it, all due to this missing feature!)

Thanks, Philipp

Please add support for power meter sensors. I use Locous Map almost daily with different sensors, own dashboard etc. Unfortunately, I always have to switch to another app to see my power data. Thank you very much.

Any news on this matter?

Any development would be really apreciated, also based on whatever fee modell.

Thanks, Christian

As an experienced developer I don't think so, it is such a huge development effort.

You have your bluetooth layer, your data model, your settings and visualization subsystem in the code already.

Adding one another type of bluetooth data-source into the already existing ecosystem is not a big deal.

Series of data is coming over bluetooth and a little algorithm to make some sliding-window average calculation, then persent it as a number (like heartbeat, cadence) is peeeenuts.

So there must be another reason(s) behind, just that sounds not as good as explanations above.

Hi guys,

the explanation was mentioned earlier. Most of the app code that works with sensors needs to be written from scratch. The original code is around 8 years old and needs a major update. The good news, I'm already slowly working on it ...

Thanks for the update Menion. Good to hear it is not completely forgotten. Now that also the chinese powermeters are working well at an accessible price, these also make sense for the "average joe" so I guess the demand for this feature is increasing.

So for us who can't directly contribute to the coding, all we can do is keep bumping the thread ;) (sorry for being a bit of a pain in the rear Menion)

Philipp

Maybe It should be moved to GitHub with a licence you prefer and we could contribute to development... welcome to 21th century of community development.

Hi guys,

support for "Power sensor" was just added to the new Beta version of Locus Map 4. Because I still do not own the power sensor itself, the test is more than needed. Thanks.

Beta version discussion. Download link is in my signature at bottom of the linked post.

Menion

I tried my Favero Assioma Duo powermeter pedals and they worked nicely.

Connection with pedals found easily and I got powermeter data to Locus Dashboard.

Nice work 👍🙂

Great news!

I just downloaded the beta version. In the sensors manager I select Power Meter. If I enable the sensor I get the message:

"Hoppla!

Bitte Gerät neu starten

ANT Manager, code: 11216"

What could be wrong here? I have a 4iiii power meter:

https://4iiii.com/usa/products/pdp/left-side-precision-powermeter-ride-ready/

Thanks, Christian

Thanks Menion for the update! Tested with my Sigeyi power meter, some issues found and reported in the Beta thread. Let me know if you need any further data.

Hi Menion, thanks for the feedback so far, I finally got some time to re-check:

So my 4iii power meter works on bluetooth as well. It connects this way to an other cycling app "Cyclemeter" via bluetooth well and I also see it in the general list of bluetooth devices of the phone.

But in Locus unfortunatelly, the powermeter bluetooth device is just not found when I select "Pick bluetooth sensor". I tried several times, restarting app and device and phone.

I can easily connect my heartrate and speed sensor this way in Locus, so there seems to be an issue with the "bluetooth profile" (?) of the powermeter.

Any ideas on how to proceed with diagnostics?

Really anxious to get this running :-)

Update: Stages via Bluetooth works with 4.3.3.8! Great work, I will test the stability on longer rides...

💪 I love this Feature 🥇🤸❤

I am excited to try this out myself! But even though I am registered in the beta version program in the Google app Store I only have the version 4.3.3

Do I have to do anything in addition or download anything manually?

Hey Menion, when in your opinion the compatibility for most powermeters is good enough, could you think about adding further options for the dashboard like "average power" and "maximum power"? Especially the average power would be very useful on longer rides for managing the own performance.

Further more, after the ride it would be pretty cool to see the invest of own power in comparison to heart rate, high meters and distance.

Also if you can define the own ftp (functional treshold power), the border where you produce more lactat than you can absorb and get a visual hint for that ftp (color or something like this). Garmin devices visualize this very well.

But: these are all visions, I am so glad and happy that you now offer at least the visualization of the actual power 🙏

Hi Menion,

I did some field testing now, please find some more feedback:

- Track export to strava does not contain the power data --> really important for analyzing data afterwards. (Is the power data actually stored in the track data at all, like e.g. heart rate?)

- Live display of the data works really well, I love my new dashboard:

- The Powermeter also provides Cadence data. But this does not show up yet, see picture.

Thanks for your efforts, really appreciated!

Christian

Hi guys,

I'm glad to announce, that Locus Map 4.4 was just published yesterday and this feature is available, finally.

I have (here and also on the forum) read, that some of you do not see power values. I'll be glad to get info about sensors that work (so we may add them to the list of supported devices) and also sensors that do not work, the protocol you use (ANT/BT) and if the device connects and no data are visible or even connection is not working. Thanks a lot for the feedback and patience!

Jiří M. aka Menion

Hi Menion,

thanks for the update 4.4! Export to strava including power data works well! Excellent :-)

Cadence does not work yet with my power meter. I think it is because it is only recognized as a "Power meter", not as a device for cadence data yet:

Hope this can be fixed.

I have a 4iiii Powermeter, it is definetely capable of providing cadence data, it works with the cyclemeter app.

Thanks again, Christian
