No qr code homebase2

I have a big problem. I built my homebase 2 into our ceiling very nicely. Now my wife would remove one camera from the home base. This is because the camera goes to our daughter who has her own home base 2. But my wife removed the homebase from the app instead of a camera. I want to add the homebase again but the app asks for the qr code on the bottom. Is there a possibility to add it without the qr code? I can see the home base networking in me. I have the ip_address and the MAC address of the homebase.

You need the qr code or the qr. Take it down, take a pic and put it back.

Would be keen to see how it looks on your ceiling. Got a pic?
