    Shared Event ReedSwitchChanged()
       
        Dim payload As ListOfByte = New ListOfByte
        Dim payString As String = ""
       
        If ReedSwitch = True Then
            LedRed = True
            payString = "Open"
        Else
            LedRed = False
            payString = "Closed"
        End If
        payload.Add(payString)

        Dim uptime As Integer = Device.Uptime()
       
       
    End Event
   
    Shared Event CheckVoltage() RaiseEvent Every 2 Days
        Dim BattVolt As Short = Device.BatteryVoltage
        If BattVolt < 2200 Then
