So, I first scanned the Robothub QR code generated using Add Robot-> RAE -> Enter SSID and PW using my phone camera, this gave me the following string
ssid:<ssid>;;PASSWORD:<password-With-Errors>;;RH_PIN:<pin>;;
I then copied this into qr.io as a text example, but entered the correct characters (! and $) and then scanned this with my RAE. This showed "connecting to <ssid>" then "connecting to robothub" etc.
