Hey! Welcome, valued visitor! You’ll notice I don’t appear to have a doorbell. Don’t worry, this is for your convenience and mine. If I’m out and about you’ll be able to contact me, and I can tell you that I’m unable to answer the door right now but I value your visit. All in real time! Let’s get started: simply solve the puzzle below. The solution will let you work out the code to unlock the box next to my door. When you unlock the box scan the QR code inside, which will allow you to connect to my WiFi guest network. Once you’re connected scan the second QR code to open the virtual doorbell selector. You can then select the appropriate message for your visit. Unable to connect? Simply knock on the door and wait. If I’m home I’ll surely answer soon enough. If I’m not home or don’t want to be disturbed you should use your own judgement: if it’s urgent trying shouting through the letterbox, or maybe wait a while and then return later!
