I have a Freebox Révolution (current OS version: 4.12) that I’ve integrated using the official Home Assistant integration: Freebox - Home Assistant
The documentation says:
Presence detection
This platform offers presence detection by keeping track of the devices connected to a Freebox router.
The integration created 3 devices:
- Freebox Server (r1)
- Disk 0
- and an IP camera
… but I can’t find any Freebox-related presence or device tracker entity for my wifi-connected devices. 
Am I doing something wrong?
