Foreach loop vs if/elseif in nested hashtable using Powershell

My goal is to create a PowerShell script that monitors host hardware health and alerts (via exit codes) if a component status is not "GREEN". The following information is pulled from the software API as a hashtable by default.

For readability purposes, this is the information in JSON format, which I converted using the convertto-json cmdlet:

"host":  {
             "serial_number":  "55555",
             "status":  "GREEN",
             "name":  "hostname",
             "raid_card":  {
                               "serial_number":  "55555",
                               "status":  "GREEN",
                               "product_name":  "PRODUCT",
                           },
             "battery":  {
                             "percent_charged":  100,
                             "health":  "HEALTHY",
                             "status":  "GREEN"
                         },
             "accelerator":  {
                                      "temperature":  36,
                                      "status":  "GREEN"
                                  },
             "logical_drives":  [
                                    "@{serial_number=55555555555; health=HEALTHY}",
                                    "@{serial_number=55555555556; health=HEALTHY}"
                                ]
         }
}

If any of the components (battery, raid_card, accelerator or logical_drives) is not green, then the top host.status value would change to "RED."

The logic I envision is to do an initial if statement in which if host.value is "GREEN" then exit 0 (meaning it is up) and just output a message.

Else, do a foreach loop to search and identify which component is not "GREEN." This is where I am stuck with the logic.

The first problem I have is not knowing if a foreach loop is most appropriate for this problem. If it is, how could you structure the foreach loop since one of the components, logical drives, has a nested hashtable inside.

The second problem I have is how could you retrieve the component name if the status is not "GREEN"?

I didn't get far but this is the structure I was initially going with:

if (host.value -eq "GREEN"){
Write-Host "Message: host hardware is healthy"
Exit 0;
}

else{
    foreach ($components in $response.host){
       if ($_.status -ne "GREEN){
       Write-Host "Message: host.??? is not healthy"
       Exit 1;
       }
}

One alternative structure is to just do if/elseif statements instead of the foreach loop. The problem with this is that it is not very elegant and its repetitiveness suggests there is a better way.

if (host.value -eq "GREEN"){
Write-Host "Message: host hardware is healthy"
Exit 0;
}

else{
    if (host.raid_card.status -ne "GREEN"){
    Write-Host "Message: host.raid_card.product_name is not healthy"
    Exit 1;
    }

    elseif (host.battery.status -ne "GREEN"){
    Write-Host "Message: host battery is host.battery.status"
    Exit 1;
    }

    elseif (host.accelerator.status -ne "GREEN"{
    Write-Host "Message: accelerator temperature is host.accelerator.temperature"
    Exit 1;
    }
}

Any recommendations on how to better structure this would be appreciated!
