Your QR code is your key for connecting to your controller which you need to keep safe.
It is highly recommended not to remove the sticker from the controller as this will make it harder to find, identify and claim the controller for your site.
If you happen to lose your QR code, you will need to email support to purchase a new QR code. Additionally you will need to download and use zcct to scan the controller to obtain the serial number and GTIN.
