Use case as/with tag
Closed this issue · 4 comments
Hi, I'm just wondering is this can help me achieve such a scenario:
I have working face recognition using my door camera, and want to unlock the doors with it, but i am aware of false positive, so my idea is to generate one minute valid qr-code and send it to recognized person phone. Then person have to scan it using my door camera.
I believe that generated tag have to be added to home assistant tags, and removed on scan or validity ends
Is qr-code-generator a way to go ?
Instead of using the tags, you could create a text helper which contains the current "access code". You then display this code via template in the QR code. When the QR code is scanned, you simply compare the two values, open the door accordingly and change the code.
Thats the way I would do it
Yeah, I followed your way and it is working fine :) Thx for idea and project :)
There is this integration that enables QR-Code recognition from cameras.
