Reading related Data

I'm trying to figure out what's wrong here. Is not very complex but I was sure I had everything in order.

I have two models, Machines and Devices. I'm constructing a table for theDevice where, in one column, I show a property of the related Machine.

Here is the declaration of the relation between these two models:

public class Device
{
    [Key]
    public int DeviceID { get; set; }
    public int Id { get; set; }

    public Machine Machines { get; set; }
    public DeviceStatus DeviceStatus { get; set; }
}

public class Machine
{
    public int Id { get; set; }
    [Display(Name = "Modelo")]
    public int TypeID { get; set; }
    [Display(Name = "Serial")]
    public string MchName { get; set; }

    [Display(Name = "Tienda")]
    public int StoreID { get; set; }

    public virtual ICollection<Device> Devices { get; set; }
    public Store Stores { get; set; }

}

Here is the Get Method for the Device model. Note: This code is inside the MachineController since I won't be doing much with the Devices beyond this list

    public async Task<IActionResult> Contadores(/*int? id*/)
    {
        var listacontadores = _context.Devices.Include(i => i.Machines).AsNoTracking();
        return View(await listacontadores.ToListAsync());
    }

And this is the View:

@model IEnumerable<Application.Models.Device><table id="contadores" class="table table-bordered table-hover table-striped" ><thead><tr><th class="col-md-2">ID Contador</th><th class="col-md-2">@Html.DisplayNameFor(model=>model.Machines) </th></tr></thead><tbody>
    @foreach (var item in Model)
    {<td class="col-md-3"><input form="@(String.Format("{0}{1}","form",item.DeviceID))" type="hidden" asp-for="@item.DeviceID" /><div class="form-group" form="@(String.Format("{0}{1}","form",item.DeviceID))"><div><input form="@(String.Format("{0}{1}","form",item.DeviceID))" asp-for="@item.DeviceName" name="DeviceName" readonly class="form-control" /><span asp-validation-for="@item.DeviceName" class="text-danger"></span></div></div></td><td class="col-md-2">
                @Html.DisplayFor(modelItem => item.Machines.Id)</td>

About these lines:

1) In the header

<th class="col-md-2">@Html.DisplayNameFor(model=>model.Machines) </th>

The Problem

2) The problem is in the body. This line:

@Html.DisplayFor(modelItem => item.Machines.Id)

This is showing a blank space in the table. Nothing.

Anything else I should check? Thanks in advance.
