I've recently switched to using Locative and it's been awesome. Locative for presence sensing
I hope that some day the Hubitat app presence can be relied upon, but meanwhile I use a combination of "iPhone WiFi Presence Sensor" and Locative. Combined Presence uses the combo and with that I've finally reach the holy grail of "reliable enough**" presence.
**I still wouldn't rely upon presence for opening locks and garages, but that's my risk aversion. But for lighting etc. I'm happy to do so.
