fritz platform offers presence detection by looking at connected devices to a AVM FRITZ!Box based router.
To use an FRITZ!Box router in your installation, add the following to your
# Example configuration.yaml entry device_tracker: - platform: fritz
The IP address of your router, e.g.,
192.168.1.1. It is optional since every FRITZ!Box is also reachable by using the IP address 169.254.1.1.
See the device tracker integration page for instructions how to configure the people to be tracked.
