How do you add a device?
To find your device IP address head to Settings > Network > About.
This will tell the controller how to talk to the device.
If this application doesn't work you'll need to allow 'Control by mobile apps'.
To do this head to Settings > System > Advanced system settings > Control by mobile apps and set this to "Enabled"
This is required and will allow anyone on your local WiFi network to use apps such as this one.
