World Wide PC Remote Overall Help
lets you to control your PC using your iPhone
you can remotely control include:
Devantech USB relays, which let you turn on and off lights in your house, open /
close your garage door, etc.
or software that react to UDP messaging,
Restarting/Shutting-down your PC and other PCs networked to yours, and
Waking up of other PCs, which support Wakeup on LAN functionality,
networked to yours.
A little more context:
for the iPhone comes in a lite and full version. Here is a recap of what’s the
same and what’s different about them:
Devantech USB relays (*)
/ Shutdown your PC
multiple commands from one button
models supported: USB-RLY02, USB-RLY08, USB-RLY16,
USB-OPTO-RLY88, and USB-OPTO-RLY816
for the PC is made up of two separate programs. There is one program that you
see (wwPCRemote Application), and another program that you do not see
(wwPCRemote Service). The program you don’t see works in the background
reacting to commands from both your iPhone and the wwPCRemote Application.
wwPCRemote Service starts working when you turn your computer on. In this way
you don’t have to first log on to Windows before your iPhone can start sending
commands to your PC.
1.0 The wwPCRemote iPhone app
wwPCRemote iPhone app has a set of buttons that allow you to control your PC.
In behind the buttons there are setting windows. The setting windows allow you
to give names to your buttons, and set up button command and other options.
1.1 Button titles and commands
you first start wwPCRemote you will see a series of blank buttons.
wwPCRemote Lite only supports two buttons, wwPCRemote supports 80. For
wwPCRemote there are 8 buttons per screen, for a total of 10 screens.
the up/down/right and left arrows allows you to navigate to the setting screens
where you can give titles to the buttons and also set button commands.
example from the first screen, press the down arrow once to go to the screen
that allows you to change the button names for the first screen, and then press
the down arrow a second time to change associated the command values.
values are listed in the section below entitled ‘3.0 Command Reference’.
1.2 Menu Control on your iPhone
full version of wwPCRemote has 10 screens of buttons.
you want to move quickly between screens, you can assign commands starting with
two greater than signs ‘>>’ followed by a screen number (between 1 and
10) to jump to the associated screen.
example you can have a button on screen 1 entitled ‘PC Commands’ with a command
value of ‘>>5’ (without the quotes).
this case, when you press the ‘PC Commands’ button wwPCRemote will jump to
screen 5, where you can have, for example, your Restart and Shutdown commands
can also press where the page number is shown on the buttons screen to be
returned to the first opening button screen.
navigation command ‘>>Exit’ (without the quotes) immediately quits
wwPCRemote for the iPhone.
1.3 Misc. Settings on the iPhone
Address / URL
wwPCRemote to communicate with your PC, wwPCRemote must know where your PC is,
and it must also know what internet port number to use to communicate with it.
easiest way to do this is to set up a link using a dsn service provider.
dsn service provider (such as no-ip.com) provides a link that you can use to
connect wwPCRemote to your PC.
are the steps you would take to set this up:
up for a free account by following this link
the instruction at No-IP’s support – Getting Started page to set up a link.
Use the port 80 redirect option to redirect communications between your iPhone
and your PC on the internet port that you identify on the wwPCRemote
Applications Settings screen (default is 55123 – there is more information on
password for communicating with your PC
note the password set on wwPCRemote on your iPhone and in the PC application
must match exactly. Passwords are case sensitive.

2.0 The PC Remote Application:
wwPCRemote Application has five main screens:
click on the tab bar at the top to the screen to change between screens.
2.1 The Button and Command screen

can also have wwPCRemote run a command on your PC, buy clicking on the
associated button on the Button and Commands window.
2.2 The Settings Screen
settings are defined here. These
your iPhone to connect to your PC it must do so via an internet port. By
default wwPCRemote uses port 55123; however this number can be any number
between 49152 and 65534 inclusive.
wwPCRemote PC application also needs to communicate with the wwPCRemote PC Service.
This is done thru the port number 1 greater than the internet port number; by
default 55124. You only need to enter the Internet port number.
security purposes you need to enter a matching password both here and on your
iPhone for wwPCRemote to action commands from your iPhone. Passwords are case
restrictions are a feature of wwPCRemote which you can use at your own option.
restrictions allow you to set a ‘home base’ and then have wwPCRemote process,
or not process, commands from your iPhone based on how far away from your home
base your iPhone is (according to your iPhone GPS locator feature).
relation to distance restrictions, you have three choices:
1. Process all commands regardless of the distance between your iPhone and your
2. Never processes commands once your iPhone goes beyond the distance(s) you set
3. Process commands when your iPhone goes beyond the distances you set but only when you override the distance option for a particular command.
For example, you may want to turn on or off a house light using a relay switch command
from anywhere in the world, but you may only want to open your garage door (using
another relay switch) if you are within 300 meters of your house.
Checking the option ‘Allow distance restrictions to be overridden’ provides for just that.
To override a distance restriction, either have your iPhone button command start
with an asterisks ‘*’ (for example “*Relay 3 2 On”) or have your iPhone send a
command that is just an asterisk ‘*’, after which time the next command will
have it distance restriction overridden.
If you set up a Distance Override button (a button with an associated command having
in it just a single asterisk ‘*’) and use it, the location icon at the top of
your iPhone’s screen will blink until the next button is pressed. When the
next button is pressed the distance check will be bypassed (assuming the PC
Settings allow for that). If after you press the Distance Override button you
decide you want to cancel it, just press the Distance override a second time
and it will be cancelled.
In association with the Distance Restrictions, you can elect to enforce horizontal restrictions, vertical restrictions, or both.
For example you can choose to enforce a horizontal restriction within a 300 meter radius
of your house (remembering of course this is based on your iPhone’s GPS locator
which has some inaccuracies associated with it). You can also choose to
enforce vertical restrictions, for example if your home base is on the 12th
floor of an apartment complex.
Horizontal and vertical restrictions can be set independently, and be based on feet,yards, miles, meters or kilometres.
To set your home base location, click the ‘Set Base Location’ button and follow the instructions. You will need your iPhone with you as part of this process.
With time restrictions enabled, wwPCRemote treats
commands from your iPhone as if they had a 'best before date'.
After that you set a time tolerance on the wwPCRemote
PC's Settings Screen.
Once done, and with time restrictions enabled, wwPCRemote
will reject commands which it receives outside the time tolerance you have specified.
For example, if you set the time tolerance to 60
seconds, a command sent now will 'expire' in 60 seconds. In this
assuming your iPhone and PC's clocks are synchronized, the command cannot if 'overheard' on the internet be reused by someone else five minutes
2.3 Service Screen
can be used to start and stop the wwPCRemote Service (the program that works in
the background to process commands from your iPhone).
click on the ‘Start’ or ‘Stop’ button to start or stop the service.
the service is stopped wwPCRemote’s settings cannot be changed and no commands
will be processed from your iPhone.
on the ‘View log’ button to see wwPCRemote Service’s activities (assuming the
Log Activity option is checked on the Settings Screen).
note the Activity log is cleared out each time the wwPCRemote Service is
started (including when you turn on your PC).
2.4 Help and License Screens

3.0 Command Reference
is the format of the various commands as they relate to:
Sending UDP Messages
Controlling Devantech USB relays
Running a PC program or script file
Waking up, Restarting and Shutting Windows PCs
Running multiple commands with one button
3.1 Sending a UDP message to other computers on your network:
[* / IP address] [Port]
IP address (values are: * ! xx.xx.xx.xx):
is short for 255.255.255.255 (used for a system wide broadcast)
! is short for 127.0.0.1 (loopback address)
specific IP address, for example 220.127.116.11
Port (values 49152 thru 65532 inclusive)
Encoding (optional values: Ascii
BigEndianUnicode Unicode UTF32 UTF7
if not present Unicode is assumed
Message (value whatever you like)
can contain numbers, letters and special characters. If you need to send a
control code (such as ascii code value 10) then code \nnn where nnn is the three
digit (leading zero) ascii code ( such as \010 ).
are a few examples:
* Hello there
Ascii Hello there
18.104.22.168 Hello there \013\010
3.2 For controlling Devantech
Relay [Com Port Number] [Switch]
[On/Off/Flash/Toggle] [Flash time]
Com Port (values 0 thru 24):
Com Port is the Com Port the Relay is attached to. For example 3 for Com Port
have more than one Relay board attached you can use a Com Port 0 (zero) if you
want your command to apply to all Relay boards.
Switch (value 0 thru 2, or 0 thru 8 depending on the relay board
model(s) you have)
is the number of the relay switch on the board, for example 2 for relay switch
value of 0 (zero) refers to all switches on the board.
turn the switch on
turn the switch off
Turn the switch on if it is off, or off it if it is on for a brief period.
The default flash time is 1 second.
Turn the switch on if it is off, or off it if it is on.
Flash time (value 1 thru 4000)
time in milliseconds that the switch will flash, for example 1500 (for 1.5 seconds).
coded, the default of 1000 milliseconds (1 second) will be used.
are a few examples:
4 2 On
the board that is connected to Com Port 4, turns switch 2 on)
0 0 Off
all switches off)
5 7 Flash 1500
board that is connected to Com Port 5, flash switch 7 for 1.5 seconds).
Running a PC Program or Script file
Run [Program / Script File] (Parameters)
Program / Script File
Enter the full path and program name or script file name
surrounded by double quotes ( " )
When entering the full path and program name or
script file name the slashes need to be doubled;
that is to say if at the Windows Command prompt
you would normally type
for wwPCRemote you will need to type
Optionally you can also add parameters to be
passed into the PC program or script file that will be run
are a few examples:
Run "c:\\temp\\test.bat" 12345
The program or script file will run as if it was run from the Windows'
However there is one important limitation:
The program or script
file cannot cause an interaction with the user desktop.
So for example, if you have
a script file that copies one file to another, then the script file does
not need to access the desktop and it will run fine.
However if you have a
script file that launches Microsoft Notepad then the script file would
cause an interaction with the desktop and it will not run correctly.
3.4 For Waking Up, Restarting, and Shutting down
Enter a command as 'Wakeup', ‘Restart’ or ‘Shutdown’ (without the quotes) followed by a space and then the MAC Address of your computer.
note: the MAC address of your computer is much like a unique serial number
associated with the hardware in your computer which connects to the
The MAC address of your computer is displayed on the
wwPCRemote PC Application's Setting window.
wwPCRemote will let you shutdown or restart any Windows
computer on your network, however, for this to work the wwPCRemote PC must
be running on those computers.
wwPCRemote will let you wake
up any Windows computer networked to the primary Windows computer which
wwPCRemote interacts with, assuming that the computer to be woken up
supports Wakeup On LAN functionality and it is correctly configured to do
so. wwPCRemote can not wake up the primary computer that wwPCRemote
Please Note: For Windows 7, and earlier, Wake Up On LAN
is supported when your computer has been shut
down, is hibernating or sleeping. In Windows 8 Microsoft changed
the behavior of Wake Up On
LAN so that is only supported from a sleep or hibernation state. For more information please see:
3.5 Running multiple commands with
feature is only available in the full version of wwPCRemote
build a simple text file with the commands you would like run, for example
create the file
Relay 3 4 Off
Relay 3 6 Off
Relay 5 2 Off
move the Bedtime.txt file to the same directory the log file is store in.
find out what directory the log file is store in, go to wwPCRemote PC
application’s Services screen and click View log. The second line in the log
file will tell you the folder it is saved in.
one of your wwPCRemote iPhone buttons, just enter an associated wwPCRemote
iPhone command of:
‘@’ sign tells wwPCRemote that there is a file to look for called BedTime.txt
in the same directory as your log file, and that contains a list of commands to
note, depending on your Windows settings, you might not see the .txt extension
after the file name that you create, or you may inadvertently create a file
help reduce confusion, go to the Windows – Control Panel, select View by Large
Icons, select Folder Options, click on the View tab, and uncheck the option
‘Hide extensions for known file types’, and click on ‘OK’.
World Wide PC Remote first time setup
For wwPCRemote on your iPhone and on your PC to communicate with
each other you must setup a path for communications.
First, something to be aware of:
When entering the IP address on the iPhone/iPad app’s wwPCRemote Setting screen ...
If you are at home and
your iPhone / iPad is connected to the internet using wi-fi then some
routers will not let you connect your iPhone/iPad’s directly to the
computer running wwPCRemote using your public IP address. That is to
say if your public IP address is, for example, 22.214.171.124 your wi-fi
connected iPhone / iPad may not be able to reach to the computer running
wwPCRemote using that address.
In these cases, you
can set up the iPhone/iPad app’s wwPCRemote Setting screen to use the
internal network IP address of the computer running wwPCRemote; for
To determine your PC’s
public IP address, you can just go to Google and do a search on “what is
my IP address” and it will be shown to you in big bold numbers.
To get your PC’s
internal IP address just double click on the wwPCRemote icon on your
Windows PC, then click the ‘Service’ tab, and then click on the ‘View
Log’ button. Near the very top of the log there will be a line that
says 'This PC's internal IP address is: ...'
If you have a fixed IP address, you can set it up by simply typing it in
the wwPCRemote iPhone app's Settings (Misc.) window as follows:
http://xx.xx.xx.xx:yyyyy (where xx.xx.xx.xx is your fixed IP address, and yyyyy is the internet port that wwPCRemote uses to communicate
default port 55123))
Please note the direction of the two slashes after the http:
They are forward slashes; that is to say “//” not “\\”
If your IP address changes from time to time you can use a free service
to manage it, here's how:
What you will need is a free 'host name' redirected to the internet port
wwPCRemote communicates (by default port 55123).
Just go to no-ip.com and no-ip.com, click on the 'Support' tab, and then
click on where it says 'Getting Started guide'.
getting started guide is excellent, just walk thru the instructions to
set up a host and redirecting commutations the
internet port wwPCRemote communicates (by default port 55123).
Here is a screen shot showing the 'Add a host' window and how to fill it
You may need to allow a few minutes for these changes to take effect.
No-IP also offers a free software program which runs on your PC and
automatically updates the No-IP system with your new IP address when it
Here is where you can get that software:
Once you have done this, go to wwPCRemote for your iPhone and enter the
host name on the Settings (Misc) screen.
Also, for security purposes, you should also set a password on the wwPCRemote for your iPhone Settings (Misc) screen. Please note, passwords are case
Here is an example.
Finally, go to the wwPCRemote PC Settings window, update the internet
port if you don't want to use the default, and changes the password to match
the one you entered on your iPhone (again, passwords are case sensitive).
Note: Your connection may not work if your iPhone is using
the same WiFi Network
as your PC. In this case, just turn your iPhone's WiFi connection off (use 3G
as an alternative) to enable the connection.
Depending on your system, you may have either one or two active firewalls; one associated with
Windows and another associated with your router.
You will need to allow access to wwPCRemote to the internet through
For your firewall associated with Windows (for example Windows Firewall,
Norton, etc.) this is
usually done by clicking on 'allow' or 'unblock' when you are
prompted by your Windows firewall system to allow wwPCRemote access.
Beyond allowing wwPCRemote access, you may also need to open
up the internet port that wwPCRemote uses. By default wwPCRemote uses TCP port 55123 to communicate with the
internet. Microsoft's write up for adding a port using the Windows Firewall
can be found
here. If you are not using Windows Firewall, just do an internet search (google/yahoo/etc.)
for 'firewall open port <the name of your firewall>' for more
For the firewall associated with your router you need to check your
router manual (usually available from your router's manufacture).
To test the connection, press the 'Test' button on the wwPCRemote iPhone
app Settings (Misc) screen.
If everything is working fine your wwPCRemote iPhone app will report the
version of the wwPCRemote PC software with which it is working.
If when you press the 'Test' button on the wwPCRemote iPhone app the
message 'Test Failed - PC Connection' appears then the most likely reason is
that communications are being blocked by
your firewall(s). For more information, please see the section
entitled 'Firewalls' directly above.
A secondary, less likely reason, is the wwPCRemote Service is not
running on your PC. To check this just start wwPCRemote on you PC, if
the Service tab says 'Service (Stopped)' then just click on the Service tab
and then click the 'Start' button.
