Just moved and left my SmartThings hub at the old house, going with a different hub. I was never able to do a whole lot in the old house (aluminum wiring and small boxes) but the switch to the new app never really seemed like it was well thought out. There were times when I needed to use my phone to unlock a door because a presence sensor was dead and it just sat there and spun in circles. Just never really cared for it. So I’m giving something else a try, who knows, I may like this even less.
In my opinion, Samsung’s weakness has always been its software. They typically make amazing hardware, but the software to back it up is just not up to the standards I would expect for such a large company. And it’s usually at a basic level that it fails, and the issues sit there for months or years without getting fixed.
