Using Synology Router for presence detection

I have been trying to set up presence detection using Synology Router 6600 by adding the following to yamil using the File Editor. (replaced the HOST with my router IP and added correct admin password" Nothing shows up on entities after restart

Example configuration.yaml entry
device_tracker:
  - platform: synology_srm
    host: 192.168.1.254
    password: YOUR_ADMIN_PASSWORD

Hi, welcome to the forum!

Have you seen this: Device tracker - Home Assistant and device_tracker → known_devices.yaml

According to that, your config is not OK.

Thanks. I will check again.
