I live in a rental house, where port forwarding my raspberry pi seems to be impossible. --> The IOS presence detection does not work, if home assistant isn’t an available outside home network. Nmap on the other hand is slow and unreliable. And if I have understood correctly also owntracks and other precense detection methods need outside network access to home assistant.
Is there any way to set up a reliable presence detection with just local network? Any ideas please.
Bluetooth seems to work reasonably well for me. It won’t detect you a block away but can detect you close to the front door. A lot will depend on house construction, HA location, etc.
