How do I install TellStick 3? (hub 1 pre-release)

1. What do I need before I start?

  • Telldus account (created for free in the app or on the web).
  • Camera – Take a clear photo of the QR and activation code first . On this preview, the QR code is right where the power cable goes in, so once the cable is plugged in, the code is almost completely hidden. A photo allows you to scan or enter the code later without having to disconnect the wiring.
