For whatever consolation it may be, it's definitely not just a Hubitat issue -- consistently & reliably cracking the presence nut has proven elusive on all platforms -- there are just SO many unique variables to account for.
I realize folks here will say solution XYZ works great for them (and that's great), but there'll be an equal number of users who will say XYZ totally blows, so there's that.
Unfortunately, it takes some trial-&-error to find a solution that works well for you & yours. For me & my wife (no kids), HomeKit has ended up working best, but it's still not a perfect solution. I'm just no longer motivated to chase after more refinements or some other solution.
