Once you add other devices, you're going to have a hell of a hard time opening and closing multiple apps for the different devices; on a daily basis.
Ex: my home automation setup consists of a garage door, door lock, sensors and hvac all controlled via ST; otherwise it is 4 different apps!
If you have all of your devices going through a hub and it fails, you lose all those devices.
If they can still work without a hub you can use their respective apps to still function them.
I mentioned Alexa and Google Home. There are devices that work directly with that device without a need for a hub to consolidate them.
