.SYNOPSIS Defines results from Get-LifxDevice .DESCRIPTION This cmdlet processes results from Get-LifxDevice so as to add more descriptors such as the Name, Group, and Power state. .EXAMPLE Get-LifxDevice | Initialize-LifxDevice .EXAMPLE $devices = Get-LifxDevice Initialize-LifxDevice -Device $devices[0] #> function Initialize-LifxDevice { param( #a discovered Lifx bulb (use Get-LifxDevice) [parameter( Position = 0, Mandatory = $true, ValueFromPipeline = $true)] [PSCustomObject[]]$Device ) #declare the counters [int]$Total = $Input.Count [int]$Count = 0 #process $Input | ForEach-Object { #constants $Port = "56700" $localIP = [System.Net.IPAddress]::Parse([System.Net.IPAddress]::Any) $RemoteIpEndPoint = New-Object System.Net.IPEndpoint($localIP, $Port) $receivingUdpClient = New-Object System.Net.Sockets.UDPClient($RemoteIpEndPoint) $receivingUdpClient.Client.Blocking = $false $receivingUdpClient.DontFragment = $true $receivingUdpClient.Client.SetSocketOption([System.Net.Sockets.SocketOptionLevel]::Socket, [System.Net.Sockets.SocketOptionName]::ReuseAddress, $true) #Device packets [Byte[]]$getLabelPacket = New-LifxPacket -Type "GetLabel" | Convert-LifxPacketToBuffer [Byte[]]$getGroupPacket = New-LifxPacket -Type "GetGroup" | Convert-LifxPacketToBuffer #send the GetLabel packet $send = $receivingUdpClient.SendAsync($getLabelPacket, $getLabelPacket.Length, $_.IPAddress.Address, $_.IPAddress.Port) #get the Label start-sleep -Seconds 1 $labelResult = $receivingUdpClient.Receive([ref]$RemoteIpEndPoint) $itemLabelName = [System.Text.Encoding]::UTF8.GetString($labelResult, 36, 32) $_ | Add-Member -Name 'Name' -Type NoteProperty -Value $itemLabelName -Force #send the GetGroup packet $send = $receivingUdpClient.SendAsync($getGroupPacket, $getGroupPacket.Length, $_.IPAddress.Address, $_.IPAddress.Port) #get the Group start-sleep -Seconds 1 $result = $receivingUdpClient.Receive([ref]$RemoteIpEndPoint) $itemGroupName = [System.Text.Encoding]::UTF8.GetString($result, 52, 14) $_ | Add-Member -Name 'Group' -Type NoteProperty -Value $itemGroupName -Force #shut the udp client down $receivingUdpClient.Dispose() $receivingUdpClient.Close() $Count++ [int]$percentComplete = ($Count/$Total* 100) Write-Progress -Activity "Initializing Lifx Device" -PercentComplete $percentComplete -Status ("$($_.Name) Initialized - " + $percentComplete + "%") return $_ } } |
