Off Help


Before you're ready to use Off you need to install the Off Helper application on any PCs or Macs you want to control. It's available for PC and Mac. The Off app needs to pair with these computers over your local wifi network before you're ready to access them over the internet. To do this just make sure you're on the same local network as the computer(s) and open the app on your phone; it will automatically discover them.

Using The App

When you start the app you will be presented with a list of all your computers discovered. Simply, select the computer from the list and you'll be presented with a list of available actions.

Setting A Password

If you wish to prevent other people with access to your local network from being able to control your computers with Off, you can set a password on your computer. To do this, right click on the icon in the taskbar and select ‘Set Password’. Enter the password you would like to use and click ‘Set’. Next time you select that computer from your phone you will be prompted for this password. If you would like to delete a password you can select ‘Set Password’ and select ‘Delete’.

Controlling Computers Over The Internet

Off can control your computers over the internet. To enable this all you need to do is have the phone connect to your computer once over your local network. If you've password protected Off on your computer make sure you've entered this password on your phone at least once.

Waking Computers

Before Off can wake your computers you may need to adjust some of your computer's settings.

Waking Computers Over The Internet

Before you try this make sure you've confirmed your able to wake your computer on your local network.

Being able to wake computers over the internet requires some configuration on your router and isn't supported by all models of router.

The specific steps will depend on your router. In a nutshell, log into your router's admin panel and find the settings on port forwarding. Forward port 9 to the ip address of your computer. You may also find it useful to assign your computer a static ip address on your network incase it changes and you're no longer forwarding to the correct address. The Off Helper application keeps your public ip address up-to-date whenever it is running. However, your public ip can change from time to time. If your ISP can provide you with a static ip address this can help avoid occasions when your ip has changed without the Off Helper application having the opportunity to connect.
