I have not seen any ecosystem that has what I would call terrific presence. This is a huge issue with home automation in my view.
What does work is to use a combined presence model. For example, use a presence fob combined with Hubitat app, or phone wifi, or Life 360, or whatever.
I use wifi, Hubitat app, and Smartthings presence fobs and get a fairly reliable model of who is home. I use jwetzel1492 Combined Presence along with Iphone Wifi Presence app (don't worry, it works for most people on Android too) .
