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.


When you start the app you will be presented with a list of all your computers. Simply, swipe left or right to find the computer you want to interact with and select the button corresponding to the action you would like to perform.


Off is still able to wake PCs if you wish to use it without installing the Helper app. However, only the wake functionality will be available and waking computers remotely will be problematic unless your ISP can give you a static IP address. It's highly recommended that you install the Helper app to make setup easier and have access to all the app's functionality. However, if you wish to set up a computer manually go into Settings and select 'Manually Add Computer' where you'll need to provide the MAC address of your computer.


No. Unfortunately, it isn't possible to control iPhones or iPads. Any app that could do this wouldn't be allowed in the Apple App Store.


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.


Off wakes up PCs using a networking standard known as Wake-on-LAN (WoL), which is supported by all modern wired ethernet adapters. Your computer may need some settings to be adjusted on it before it's ready to accept a request to wake. It's only possible to wake computers that are sleeping or hibernating. If your computer has been fully shut down it isn't possible for anything, other than the power button, to turn it on.

If your computer doesn't have a wired network connection you might still be able to wake it using Off. This is possible using a standard called Wake on Wireless LAN (WoWLAN). Unfortunately, WoWLAN support isn't very widely adopted. Please check your computer's hardware specs to see if WoWLAN is available. If so, the steps will be identical to the ones above to enable it.

To enable WoL on Windows 10, follow these steps:

  1. Open Settings.
  2. Click on Network & Internet.
  3. Click on Status.
  4. Under the "Advanced network settings" section, click the Change adapter options button.
  5. Right-click the active network adapter and select the Properties option.
  6. Click the Networking tab.
  7. Click the Configure button.
  8. Click the Advanced tab.
  9. Select the Wake on Magic Packet option.
  10. Use the "Value" drop-down menu and select the Enabled option.
  11. Click the Power Management tab.
  12. Check the Allow this device to wake the computer option.
  13. Check the Only allow a magic packet to wake the computer option.
  14. Click the OK button.

Before you try this make sure you've confirmed you're 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 in case 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. You can find detailed instructions on how to set up port forwarding on your particular router here. For more detailed information on enabling WoL over the internet look here.

If you've got multiple computers on your home network that you want to be able to wake up you'll need to repeat the steps above for each of them. However, each additional PC will need to have a separate port configured for it to forward, as port 9 will already have been taken by the original computer. Choose a different port number for each additional PC and in the Off app go into the Computer Details screen and enter the port your chose as the Wake-on-LAN port for that PC.


Off is able to wake your Mac only if it is connected to the power adapter and it is currently sleeping. It's not possible to wake it if it is turned off. The default power settings on a Mac should allow Off to wake your computer but if you find that the Off app isn't seeing your computer when it's sleeping go into your Mac's Preferences then the Battery section. Under 'Battery', there's a section called 'Power Adapter'. Make sure 'Wake for network access' is ticked there.

If you want to be able to wake your Mac when you're not connected to the same local network as it then some additional configuration is required.

Before you try this make sure you've confirmed you're able to wake your Mac on your local network. 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 1984 to the IP address of your computer. You may also find it useful to assign your computer a static IP address on your network in case it changes and you're no longer forwarding to the correct address.

You can find detailed instructions on how to set up port forwarding on your particular router here.

If you enable port forwarding on your router it's recommended that you set a password in the Off Helper.

If you were expecting to use WoL to wake your Mac, although Apple computers do technically support the same WoL standard as Windows, the usefulness of WoL has been superseded by the standard macOS power management features. Technologies such as Dark Wake leave the networking aspect of your computer powered up for it to be able to automatically wake up other parts of the system if, for example, something tried to access a hard drive on it. If you want to use WoL on your Mac you'll need to disable these features, which is not recommended.


Within the app, you're able to schedule Off to perform a shutdown etc. at any time within the next 24 hours. If you want to create a repeated schedule then the best way to do this is using Shortcuts. See the Shortcuts guide for more details.


Off doesn't have its own Widget; not yet at least. However, you can create a widget for it using Shortcuts. Watch this video to see how.


Off has extensive support for Shortcuts and Siri. See the Shortcuts guide for more details or watch these videos.


Using the app's support for Shortcuts it's possible to make a button that you can place on your home screen that will trigger your computer to shut down, restart, wake up etc. What this video to see how.


If you're having problems using Off try the following:


The first time Off is opened iOS should prompt you to grant Off access to find and and connect to devices on your local network. If this wasn't accepted, Off won't be able to find your computer or perform any commands on it until you enable this permission manually in your iOS device's Settings.

  1. On your iOS device, open the Settings
  2. Scroll down the list until you find Off
  3. Turn on the toggle for Local Network access

Not really. Services aren't allowed to interact with the UI, which would limit Off's functionality.


It's possible to perform most actions when multiple accounts are logged into your Mac. However, shutting down or restarting your Mac causes an administrator password prompt to be shown, which Off can't get around at present.


Macs already have Bonjour as part of the OS so you don't need to do anything to configure it. However, Windows needs this to be installed separately. Off needs this in order for it to discover your computer on your local network.


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/status bar on your computer 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’.


If the Off app has found your computer but when you try to trigger it to shutdown etc. you see an error saying "Unable to connect to computer" this normally means that there's an issue with your firewall. To fix it, go into your firewall's settings and make sure the Off Helper app is allowed to make inbound and outbound connections on port 1984. If your firewall is configured correctly and you're still experiencing the same error, check that in your phone's Settings, Off has got the Local Network access toggle turned on.


On Windows, Off requires Bonjour in order to discover your computer. The Bonjour SDK is installed automatically when you install the Off Helper. If Off displays a notification saying 'Unable To Register Off on Network' this normally means the Bonjour service isn't running. To fix this, on your PC open the Start menu and search for Services. The search results should contain an application called Services, which you need to open. This application will display a list of all the services installed on your computer. Scroll down the list and find the 'Bonjour Service'. When it's working properly it should say 'Running' next to it. If it doesn't click 'Start' to start it. If it's not displayed on the list you need to reinstall it. You can download it from here. To prevent failures like this in the future, right click on the Bonjour Service in the services list. Go to the Recovery tab. For First failure, Second failure and Subsequent failures select 'Restart the Service'. This will automatically restart Bonjour if it ever encounters an error.


Off supports any version of Windows from XP onwards.


If you need to install the macOS app on a Mac running macOS 10.11 or earlier an earlier version of Off for macOS can be downloaded here. Note: this version is unsupported and doesn't offer the full range of features.


Occasionally Windows Defender decides that Off is bad. There doesn't seem to be any particular pattern to this; some machines will get this warning and others won't. It is due to Windows Defender being overzealous about the app being new and unfamiliar to it. So long as you've downloaded the Off Helper directly from BridgeTech.io it is safe to ignore this warning.
