Use snapshots from a camera connected to Homey, and let Face++ do AI based face recognition. For every face the app detects, a flow will be triggered. Homey will automatically try to match the faces to a set of known faces that you can upload yourself. The app will also estimate gender, age, emotion, and whether the person is wearing (sun)glasses or a mask.

The Homey app uses a cloud based face recognition service called Face++. Using the Face++ service has severe privacy implications. Use at own risk. Read and understand your local privacy legislation, and the terms of use from Face++.
The results depend very much on the quality of the snapshots. A face will be best recognized if the lighting is good and when the face is frontal with a width of at least 75 pixels. In practice it means you need to have good control over when the snapshot is taken in a videostream. The free Face++ service allows you to upload around 1 or 2 images per second. The face detection usually is ready within 1 to 3 seconds from uploading an image (via an action flowcard).
To make testing your flow easier, a test image is available as global image token. It has five faces in it.
