Not to worry, I already have hubitat and it replaced smartthings lol, however.. Someone asked me this today and I was unable to - in my opinion - adequately answer this inquiry.
What do smart hubs provide other than add on ability like wecore or node red? Hubitat itself has a rule machine but from what I have read, a lot of people choose to not use it in favor of the options I just mentioned. Security? Echo has versions of that... Geofencing? Geofencing is at best a failed technology unless you go to great lengths and MUCH trial and error to get it to work.
If I have a group of lights, and I want them on, I shouldn't need hubitat for that. So what specifically is the point of hubitat when a person already has a house full of echo devices? <--- this was the question.
I also mentioned "automations" but even then echo has stuff for that. Anyway, just some thoughts or ammunition would be great to help me should that ever come up again. Also please keep in mind I am not trying to start a heated debate here. Just some information that makes my response next time more or less undisputed. lol Thanks!
