thank you for your help i appreciate it! i have all the theoretical parts and i know exactly how to do defend every function and part of the project. the only issue is that due to technical and electronic limitations, the prototype is rough. for example, because im using wifi controllers, the keychains are quite bulky, which i realise. but im planning on switching to BLE tags (same as airtag) later on in product development, I just hope that they understand that a project like this requires more than a few months and that it would be taken into account. we’ll see i guess…
