feature request: increase refresh rate to 1min

[zibra]

We are using Freestyle Libre 3 sensor which gives BG reading to nightscout every minute. Is it possible to increase refresh rate on Nightguard as well to 1min?

[zibra]

I've found backgroundTaskScheduleRate setting, but it seems like the only way to configure it to make custom app build? It will be best to expose this as configurable setting

[dhermanns]

Yes - this is currently not supported, since no sensor was able to send every minute data. Problem is I don't have a freestyle libre to continuously test such a feature.

[zibra]

@dhermanns could you build IPA with such settings so I will test it on my end? I've tried to build project on my end but getting this error:

[dhermanns]

I had to make a small Addon to the Eureka SliderRow:

public final class SliderRow: Row<SliderCell>, RowType {

    public var steps: UInt = 20
    public var shouldHideValue = false
    public var lastSelectedValue : Float?

    required public init(tag: String?) {
        super.init(tag: tag)
    }
}

That should fix it. Would be great if you can provide a Configuration-Option for that.

Hello, Just curious....is there an update on this question, as it is open since dec2022? Many libre 3 are being used now.

Hello, Just curious....is there an update on this question, as it is open since dec2022? Many libre 3 are being used now.

I was going to ask the same thing. My son at school uses the libre3 now and it would be great to be able to have a toggle to decrease the refresh time

[dhermanns]

For me it's still the same: I don't have a libre3 and therefore cannot implement and test this. So we need someone who can test and support this.

[poml88]

I have libre3 and can test this. But I would need some input, I am not a skilled programmer. I have a working build environment here.

It seems that backgroundTaskScheduleRate was removed in the meantime? Can the 5 minute intervall be changed somewhere now?

I also noticed, that, when the app on the watch is open, it is updated rather often, but it seems to get stuck also often, then I have to use the reload arrow on the second page. Is that normal behaviour? While the app is in forground should it not continue to update?

[dhermanns]

A lot of refactorings in the meantime. But the updates frequency should still be changed very easily, since its done using a timer.

Never noticed that updates on the watch should get stuck. Yes, I would expect them to be updated every 5 minutes if the app stays in foreground.

[poml88]

Ok, I see. I am still not so familiar with the code. I did not find that timer yet. If you have a hint... ;-)

[dhermanns]

In the iOS App the timer is in the MainViewController. It already activates every 30 seconds. It uses the NightscoutCacheService.singleton.loadCurrentNightscoutData to get the latest data.

The method checkIfRefreshIsNeeded in this Service restricts the updates to 5min only.

[poml88]

Thanks, ok, found it. The currentNightscoutData.isOlderThan5Minutes() is quite hard coded... And the app quite complex. I will see if I can come up with something. A func isOlderThanXMinutes(_ minutes : Int) is already there and could be used. Have to add the switch in the preferences...

[poml88]

So, I made a testflight build with an option to select 1 minute updates. Seems to work. Where do we go from here? You want to try it out? I would have some other questions as well, Is there a way to get in touch?

[dhermanns]

Hi Phil! Simply provide a Pull Request. I will have a look. But keep in mind that you will have to provide support for this feature, since I'm not able to test this.

[Evs-nazgul]

Hey,Altough I’m nit able to write the codes, I’m willing to try if it can help?ErwinOp 20 mei 2024 om 08:47 heeft dhermanns @.***> het volgende geschreven: Hi Phil! Simply provide a Pull Request.

A single test won't help. We will need someone who checks this with every new TestFlight release. Not much work, but someone has to have an eye on this for years.

[Evs-nazgul]

Ok no problem.I’m using a freebstyle libre 3, and can test the functionality on a 24/7 base, if youvare looking for results and sustainability.All I can do is  offer the help to report if it provides results if it works.ErwinOp 20 mei 2024 om 08:58 heeft dhermanns @.***> het volgende geschreven: A single test won't help.

Great 👍

[poml88]

Hi, ok, what is the best way? It is really only 2 lines of code or so. I do another fork, just change the lines of code? If I use my current fork it will have millions of changes in the xcode workspace.

I will for sure not win a price for beautiful coding! And I also don't know the finish translation.

Are you sure you can't test? Will you not see the app look for another value, just not find one? Anyway, I think there are plenty of libre3 users out there that will report an issue. And I am also wearing a libre3 and will be around for a while, but who knows.

We can also have libre3 users test my testflight first and see if everyone is happy, if that helps.

[dhermanns]

Then a new fork with a PR would be easiest. You can omit the finnish translation.

Basic testing ist not the problem. But I would need to have a developer in case of troubleshooting. When Bugs are reported with the freestyle I wouldn't be able to reproduce them.

[poml88]

Ok, agreed for the FSL3. This very feature here is more universal I think, can work for any sensor that delivers values more often than every 5 minutes. Let's see if I can manage with this PR thingy.... :)

Great - I prepared a Testflight V3.9.2. It is available soon: https://testflight.apple.com/join/Ub8WcpcE

I was wondering, if for the prediction it makes a difference if we have one sgv every 5 minutes or one sgv every minute = 5 in 5 minutes? It depends on how this is implemented. Does it look at a time interval or a number of sgvs?

[Evs-nazgul]

Hello,What do you mean with sgv?As when I installed the flight case on the every minute update, I see  regularly annupdated value, but not every minute.What I did notice is that when I keep the nightguard app open and do nothing, the value is illediately updated after 5 minutes.The value is updated maybe faster, it is not always immediately shown on nightguard nor on an iwatch, using the nightguard to displayErwinOp 27 mei 2024 om 22:40 heeft Phil @.***> het volgende geschreven: I was wondering, if for the prediction it makes a difference if we have one sgv every 5 minutes or one sgv every minute = 5 in 5 minutes?

If I understand the code correctly it is using the last 3 values. I think that could have a big effect, because For FSL this means 3 minutes, for other sensors 15 minutes. I think we have to go 15 minutes for everyone here. 3 minutes have too much noise.

[poml88]

You can close this too.
