I have made a new installation on my qnap nas with the vmware version of HA. This works fine. After that I installed the file editor with no problem and opened the configuration.yaml.
Then I wanted to add presence detection and there it went wrong.
My lines were:
device_tracker: - platform: ping host: galaxy_note9: xxx.xxx.x.xx (ip-adress)
This gives a platform error. Ping tracker does not exist.
Does anyone know what I must change to make it work/
Thanks for helping.
