From the README

Home Assistant custom integration for Fermax Blue video door entry systems (DUOX PLUS / blueStream).
This integration simulates a Fermax Blue mobile app client, connecting to the Fermax cloud API and receiving real-time push notifications via Firebase Cloud Messaging when someone rings your doorbell.
Live video streaming — Real-time video from the intercom camera (~720x480) with the intercom's audio, over WebRTC in the standard camera cards and the companion apps; MJPEG is still served. Opening…
Talk-back — Speak to the visitor from a card that captures the microphone; the first word answers the call (see Live view and talk-back)
Answer from your phone — A ready-made dashboard and notification blueprint: ring → notification with the visitor's photo → see, hear, talk and open the door from the companion app (see Answer calls…
Camera preview — Last captured frame persists across HA restarts, always visible in the camera card
Doorbell detection — Real-time push notification when someone rings (via Firebase Cloud Messaging)
Door opening — Open your building's door remotely (lock entity + button)
On-demand camera — Triggers the intercom camera without a doorbell ring via auto-on
F1 auxiliary button — Trigger the intercom's F1 function
Switch camera — Step through the cameras of multi-camera installations while a live stream is up (the intercom only accepts the change inside a session)
Call guard — Call the building's guard/janitor
