Frequently asked questions

Q1: There is no weather data downloaded / The location of the weather is not correct / …
Getting weather to your watch requires 4 things to be right:
  • Acquire a gps position by starting a run activity and waiting for a green gps fix. Return to the watch face once you have acquired the fix. Alternatively in the settings of the app you can also set the default longitude/latitude to your home location. To retrieve the location of your city go to the website and enter your city.
  • Garmin Connect Mobile needs to run on your mobile phone (as a background process or actively as a foreground process). Make sure that you have no battery saver apps running that kill the GCM instance.
  • you need to be connected with your phone via Bluetooth (go to Garmin Connect Mobile and synchronize your watch to force an active connection)
  • your phone needs to be connected with the internet (to be able to download weather info)
Once all above things are ok you’ll need to wait until the next Internet request to happen. This may take up to 2 hours!

(TIP: change the right chart option to Weather + Time Last Update to see when the last weather update was executed)

Q2: Why is the weather shown for Brussels and not for my location?
In the settings of the app set your own default longitude/latitude to your home location (To retrieve the location of your city go to the website and enter your city). When possible the watchface will try to acquire the location of your last gps activity, but when failing to retrieve this it’ll use the coordinates of the longitude/latitude you’ve entered)

Q3: How often is the weather being refreshed?
A simple question with a not so straightforward answer as it’s dependant on several factors:
  • the fastest weather refresh rate is normally 2 hours, after filling in a donation key the fastest refresh rate becomes 15 minutes.
  • the refresh happens at regular intervals and at the moment the refresh happens there needs to be an active bluetooth connection, an active internet connection and a stored gps location (see Q1)
  • the data of the weather comes from the OpenWeaterMap weather service, if the service address returns an invalid response (or times out) then the cached data stored in the watch face remains to be shown
  • the data of the weather comes from the OpenWeaterMap weather service, this service also caches data and is also dependant on eg weather stations to provide data to OpenWeaterMap So It could be that there is no new data and that the data just remains the same….

Q4: Can I verify whether the weather fetch was sucessful?
Yes, you can set the right chart option to Weather + Time of last update. When the weather fetch is succesful it will show the time of the latest fetch in the foreground color (white by default), when the weather fetch returned an error it will show in red (See Q1 on how to resolve. For additional debug info set up a debug session, see instructions at the bottom of this article.

Q5: The weather, the active heart rate chart and/or the option to show seconds is not available on my device
  • fetching the weather requires the ability to connect to the internet which is not possible on Connect IQ 1 devices
  • always on seconds and the active heart rate chart feature depend on the always on technology to provide updates to the screen while in low power mode (this is only supported in fenix 5 derivatives and vivoactive 3 derivatives)

Q6: The sunrise/sunset time is incorrect
The sunrise time is calculated once a day and is dependent on getting a good gps fix:
  • the gps location is only known for a very short period in watch faces (only shortly after doing a gps activity). To let the watchface acquire your location do the following: start a gps activity (eg run) and wait till you have acquired a good gps signal. stop the activity and go back to the watchface.

Q7: Can I force an update of the weather and or force an update of the sunrise/sunset times?
This doesn’t work on all watches, but it’ll work on most:
  • setup everything as explained in Q1 and/or Q5
  • uninstall the watch face (see Q8) (you will lose all your customizations by the uninstallation)
  • install the watch face

Q8: I try to install the watch face but the Connect IQ store tells me I need a firmware update while I’m already at the latest version!
Solution 1: Disconnect your watch from the usb cable, likely there’s an update on your watch ready to be installed. Install this update and retry.
Solution 2: Restore your watch to factory settings from within the System menu on your watch. (Be sure to upload your activities to Garmin Connect first as all user data will be wiped from the watch.)

Q9: I can not remove the watch face
To delete the Data Lover watch face you first have to make another face the active watch face.

Q10: Setting “x” is not applied properly
Sometimes when auto-updating a watch face the settings were updated to the new version but the program itself was not yet updated and was stuck on the previous version. To fix this remove the watch face (see Q9) and reinstall the watch face. (you will have to reapply your customization to the settings when removing and installing)

Q11: I have another question!
There are several channels for support:
  • You can post your question below this article
  • You can post your question in the forum support topic
  • You can use the contact developer link on the app description page


The watchface can be downloaded from the Connect IQ Store


The watch face is fully functional without donating (there is a very occasional small message to encourage donations, refreshing the weather info occurs at a slightly higher rate after donation).

If you like the watch face you can show your appreciation by donating a small amount (suggested donation: 3 euro) on my PayPal account (Mention the name of the app: “Data Lover”). After donation you will receive a donation key on your PayPal email address which will remove the encouragement message from the watch face. (this email is a manual process, if you do not receive a donation key within 48 hours contact me via the contact developer link)

(SPECIAL PROMO: in case you like several of my apps and you want to remove donation encouragement messages from all of them, then donating one big amount might be beneficial to you. When you donate 19 euro or more you’ll get one key that’s valid for ALL my current AND future apps: )

Debugging setup (for advanced users)

The watch face contains a debug option, to set this up follow these steps:
1/ Uninstall the watch face (See Q9)
2/ Install the watch face and turn on the debug option in the settings
3/ Connect the watch with an usb cable to your computer and browse to the folder \GARMIN\APPS Remember the most recent name of the PRG file
4/ Browse to the folder \GARMIN\APPS\LOGS and create a txt file with the same name as the most recent prg file 5/ After running the watchface for a while the txt file should contain debug info about sun events and weather retrieval

    Hi Peter,
    I went exactly what you recommend, but the weather simply does not work. Sometimes I see only Brussels. I do not see the weather for my current location.

  3. Reply Peter May 24,2018 11:59

    It is the way to fix the weather though make sure to all 3 requirements. I see if I can provide an option in the settings in the next version where you can provide a city override.

    Hi Peter,

    The letter (mail) icon at the top is always on even I don’t have any unread mail. How can I fix that?

  5. Reply Peter Jun 3,2018 06:47

    The icon indicates unread notifications. In your widget loop (press down from the watchface a few times) there should be a widget that shows these messages you can mark them as read by pressing the start button.

    I have tried every fix to correct the default location from Brussels and nothing works. Can you please help?

    • Reply Peter Jun 5,2018 17:53

      hey Joshua, I have the impression that on some watch types it’s difficult to acquire the location from the last gps activity so in the next version of Data Lover I’ll be providing a mechanism so that you will be able to manually enter a longitude and latitude. Likely will be releasing the new version by the end of this week. Cheers, Peter.

    Hi Peter
    Just bought the Fenix 5x on Jun 9 2018
    Downloaded Data Lover and Data Lover has been updated
    I’m in Palm Beach, FL USA
    But the watch thinks I’m in Brussels
    The temperature capture also seems to be Brussels
    Additionally, how you change the 1/2 circles chart at the very bottom on the watch face?
    I would like, instead, to have the HR chat at the bottom.
    Also the seconds are not displaying on the digital time capture.
    And, lastly, The HRM chart: What is the length of time tracked on the chart?

    Hi, I have the Forerunner 235 with DataLover but do not have the option to set the Right chart to anything other than “Move Circles”, and similarly the bottom chart to “Step History”. I would like to set the right chart to weather/temperature but cannot seem to be find the setting.
    Is it only possible to have the weather with a different watch than the FR235?

    • Reply Peter Jul 19,2018 19:27

      the FR235 is a Connect IQ v1 watch does not support connecting to the internet from a watch face, so the option to set weather is not available on that watch. The option to set the weather is available in newer watches such as the FR735xt, Fenix5, Vivoactive3, etc…

  11. Reply AA Jul 18,2018 13:54


    Can you please advise how I can change the weather from F to C? I tried changing the setting via Garmin connect under Measurement Units to Metric and Statute UK, but the weather is still in F (even after syncing).

    Thank you

  12. Reply Peter Jul 18,2018 18:24

    You can change the units on the watch via menu Settings -》 system -》 units. After you change the unit it will take until the next weather fetch before you see it adjusted in data lover (The weather fetch is executed every 2 hours)

    Hi Peter,

    Do you plan to add the current HR as an option to be displayed in the HR graph. I have Vivoactive 3 and the current HR value will be more useful than the HR range for me. Maybe to show the current next to the range.

  15. Reply Peter Jul 30,2018 13:36

    Hi Peter. What means percentage under the move bar? i didnt find the answer in FAQ

  18. Reply Peter Aug 5,2018 08:54

    The percentage indicates how much of today’s step goal has been completed.

  19. Reply Emily Aug 7,2018 13:05

    Below my field 1 and field 2, There is a field with a percentage. It’s the same percentage, which I *think* is the percentage of steps completed toward my goal. But it’s there twice, and I cannot see that customization in the settings.

  20. Reply Peter Aug 7,2018 13:09

    Hmm. Can you post a screenshot?

  21. Reply Peter Aug 8,2018 14:50

    hi Joey, that’s a bug in Garmin Connect Mobile, it erases the app and reinstalls it instead of updating it. So when you update with GCM you’ll have to re-enter all customizations including the donation code. If you want to avoid that you can update your apps via Garmin Express on your computer.

  22. Reply Matt Aug 11,2018 18:17

    Thank you – great app !

  27. Reply Kevin Sep 11,2018 06:25

    First of all, I love this Watch face! Great work!

    I noticed, not sure if anyone brought it up already; if the weather message is too long, it will actually covered up the date field. For example, if the weather is “Scattered Thunderstorms”, the date won’t get displayed as the message takes up the entire roll. Is there anyway around this?

    Thanks in advance!


    • Reply Peter Sep 11,2018 08:38

      Yes this is by design.

      There are a “few levels” of dates that get displayed:
      – Mon, 10 Sep
      – 10 Sep
      – 10/9
      – nothing

      The version of the date that gets displayed is dependent on the width of the weather condition. As Scattered Thunderstorms does not leave enough space for the smallest version of the date to be displayed it falls into the nothing case.

      • Reply Kevin Sep 12,2018 02:43

        Hi Peter,

        Thanks for the reply. I actually prefer knowing the date than the current weather. Hopefully there is a way in the future for this. maybe scrolling weather display or using abbreviation for the weather condition?

        Thanks again!

      On your watch go to settings -> system settings -> change the units there. It’ll take up to the next internet fetch before the watch uses the new settings.

    Hi Peter,

    I just installed the latest update for Data Lover, however after the installation , the Watchface no longer works on my Descent MK1. The watch face was set back to default, when I try to change it to Data Lover, it just shows the IQ logo with the yellow exclamation mark. I tried to restart the watch and still got the same error. I have not try to uninstall then reinstall yet tho. Not sure if anyone else is experiencing this problem also?

    • Reply Peter Sep 17,2018 07:36

      To update to a new version it’s always best to uninstall / reinstall (especially if there are changes to the settings options such as in 6.0) – (unfortunately uninstall/reinstall means you’ll have to re-enter your setting customizations, so be sure to note down your changes).

      Let me know if the problem persists after uninstall/reinstall then we’ll look deeper into it.

    Hello – I have a Garmin Vivoactive 3 and I have to say I love this watch. The only problem I have with it is where it thinks it’s located. Originally it said it was in Brussels… Then it changed to the correct location (although how it did that I don’t know). Then when I was out of town it changed to that location and has been there for over a month. I can’t figure out how to make it change to my current location. I’ve followed the links and scanned through the postings, but I can’t find the answer anywhere even though it’s referenced. Can you please let me know how to update the location. Thank you!

    • Reply Peter Sep 21,2018 14:36

      The location doesn’t update constantly when you move to a new city. The only way watch faces can retrieve location is by interrogating the last gps activity (and only during a very limited time). To update the location just start eg a run activity and after the gps has turned “green” you can stop the activity and exit to the watchface. On the next weather retrieval (can take up to 2 hours) it now should use this new location.

      • Reply Jim Sep 21,2018 19:09

        Heya Peter!

    Hey Peter,

    Several months now with your apps and data fields and am loving them all. 🙂

    Quick Q on DATALOVER, when the Garmin Connect App on the iPhone is running in the background (ie open, but not in focus) all is fine. But if the app is closed, Datalover cannot sync and fetch weather. This is despite having the app enabled for use set to always in the iPhone settings.

    Does this make sense to you, or is there a way to get it to work even when not running in background.

  39. Reply Mauce Oct 24,2018 08:36

    I have set ‘right chart’ to ‘Weather + Time Last Update’.
    I found out most of the time it fails to update (I have a stable internet connection) and therefore the update time is in RED (because it failed).
    However, since the temperature displayed it the last value upon successful update I rather have the ‘time last successfull update’ below the temperature instead the red timestamp.
    Because when the timestamp is in red you can’t tell of which timestamp the temperature shown is.
    Could you please implement that?

    • Reply Peter Oct 25,2018 14:04

      I can see that this could be useful, I’ll consider adding an option for it.

      The most likely reason your weather update does not work is because garmin connect mobile is not active in the background (all internet traffic is guided through that app), make sure to disable process killers on your mobile phone (or to make an exclusion for gcm).

      The pressure in the watch face is also in millibar, but watch faces can’t access the sensor and have to take this from the pressure history samples taken by the watch, so there could be a slight delay in the pressure reading.

    Hey Peter, Love the watch face but had some questions on the GPS functionality. If I have the GC Mobile running in the background on iPhone is the watch pulling GPS data from the phone or the watch itself? For example, I’m in a building and don’t have a good GPS watch signal but my cell is pulling a location from the cell towers. Is it pulling the cell phone location? That might help with my ‘understanding’ of how this watch and the face works! Thanks for a great face!!

  50. Reply Peter Dec 9,2018 06:48

    Gps location comes from the watch. Watch faces can not execute a refresh of the location though and are limited to fetching the location of the last gps activity (eg your last recorded run session)

    • Reply Chris Dec 9,2018 16:50

      Thanks Peter for that update, definitely makes more sense now. And from studying more I’ve also learned to keep the GC app open in the background, big difference! Thanks again for your hard work on this. -Chris
