Check out Page 33 of the Profilux 4 Manual. That's where connection to your PC starts.Thankyou I found it on the sticky how to set up your profilux 3, it's still the same... one thing I don't get with these manufacturers why don't they supply proper step by step instructions, that start from the beginning with the basics time, wifi, sensors and what to expect when you turn it on for the first time, mines flashing Red with various prob errors... some explanation would help.. not a happy bunny so far..
