If you stuck your sensor to the wall before you scanned the QR code on the back, then don't worry! You can leave the sensor there and still use a QR code to install it hassle free.
Twist the sensor body counterclockwise to remove it from the base. There is a copy of the QR code on the sensor body.
When the Notion app prompts you to scan a QR code, scan the secondary one and the app will walk you through the rest of the installation process.
This option can be helpful too if you need to delete and reinstall your sensor for any reason after you initially set up your system.
