Personally I use Google Maps for myself, wife and kids. Have been using it for 18 months and, while not to the minute accurate, it’s close enough for what I use it for.
Keep in mind, I’m not turning on lights and such when I walk in the door (have motion sensing light switches for that) - more for ‘run the robot vacuum if both wife and I are gone and it hasn’t been run for 3 days’ - or turn on home office air freshener if M-F at 8am and wife is home, etc. Nothing ‘precise’.
Personally, I’d love to find a Bluetooth solution that could help more with precision and what room we’re in, etc. to get more granular - but, taken with a grain of salt, this is working well for me.
