Reatime update

Hello, I am using firestore, to store some values And I have a service, the get the value updated every second

private async void InitializeAsync() {
    if (_firestoreDb != null) {
        await LoadOrInitializeTurbineAsync();
        InitializeTimer();
    }
}

async Task LoadOrInitializeTurbineAsync() {
    var turbinesRef = _firestoreDb!.Collection(collectionName);
    var snapshot = await turbinesRef.GetSnapshotAsync();

    if (snapshot.Count == 0) {
        var turbine = new Turbine {
            Id = "EC-G-SB",
            Country = "Ecuador",
            Name = "Estación Ciudadela Simón Bolívar",
            Address = "Av. de las Américas, Guayaquil 090513, Ecuador",
            Latitude = -2.151993,
            Longitude = -79.886109,
        };

        turbine.RemovedCo2Kilograms = Math.Round(turbine.EnergyProduced * turbine.Co2EmissionOffset, 5);

        var turbineDocRef = turbinesRef.Document(turbine.Id);

private async void InitializeAsync() {
    if (_firestoreDb != null) {
        await LoadOrInitializeTurbineAsync();
        InitializeTimer();
    }
}

async Task LoadOrInitializeTurbineAsync() {
    var turbinesRef = _firestoreDb!.Collection(collectionName);
    var snapshot = await turbinesRef.GetSnapshotAsync();

    if (snapshot.Count == 0) {
        var turbine = new Turbine {
            Id = "EC-G-SB",
            Country = "Ecuador",
            Name = "Estación Ciudadela Simón Bolívar",
            Address = "Av. de las Américas, Guayaquil 090513, Ecuador",
            Latitude = -2.151993,
            Longitude = -79.886109,
        };

        turbine.RemovedCo2Kilograms = Math.Round(turbine.EnergyProduced * turbine.Co2EmissionOffset, 5);

        var turbineDocRef = turbinesRef.Document(turbine.Id);

  private void InitializeTimer() {
      _timer = new System.Timers.Timer(1000);
      _timer.Elapsed += async (sender, e) => await UpdateCO2ValueAsync();
      _timer.AutoReset = true;
      _timer.Enabled = true;
  }

  private async Task UpdateCO2ValueAsync() {
      var turbineRef = _firestoreDb!.Collection("turbines").Document("EC-G-SB");
      var snapshot = await turbineRef.GetSnapshotAsync();
      var turbine = snapshot.ConvertTo<Turbine>();
      var beforeUpdate = turbine.RemovedCo2Kilograms;
      turbine.RemovedCo2Kilograms = Math.Round(beforeUpdate + 0.0007, 5);
      turbine.FinalCo2Removed = turbine.RemovedCo2Kilograms;
      await turbineRef.SetAsync(turbine, SetOptions.Overwrite);

  private void InitializeTimer() {
      _timer = new System.Timers.Timer(1000);
      _timer.Elapsed += async (sender, e) => await UpdateCO2ValueAsync();
      _timer.AutoReset = true;
      _timer.Enabled = true;
  }

  private async Task UpdateCO2ValueAsync() {
      var turbineRef = _firestoreDb!.Collection("turbines").Document("EC-G-SB");
      var snapshot = await turbineRef.GetSnapshotAsync();
      var turbine = snapshot.ConvertTo<Turbine>();
      var beforeUpdate = turbine.RemovedCo2Kilograms;
      turbine.RemovedCo2Kilograms = Math.Round(beforeUpdate + 0.0007, 5);
      turbine.FinalCo2Removed = turbine.RemovedCo2Kilograms;
      await turbineRef.SetAsync(turbine, SetOptions.Overwrite);

     public double finalCo2Removed;

  [ObservableProperty]

     public double finalCo2Removed;

that gets updated every second in the data in the database like this https://reccloud.com/u/edxlrsd I am trying to bind this value and see when the value rise in my collection view but when I bind I get 0

You can just use the Windows Snipping tool no need to use some random website to record which doesn't even have a video embed for Discord
