I’ve found that combining Bluetooth (through monitor) and WiFi (using the nmap tracker because of issues with my router), gives me a fantastic home/away detection ability.
If you’ve got a front door sensor you can use automations to improve the logic, such that it requires the door to recently have been opened before somebody can be marked as home or away. I found doing that has removed the false positive aways (I’m less worried about false positive home detections).
