I can totally see a point in some of the features.
The other day my wife and I got 20 minutes from home before I said “oh shit I don’t know if I turned the oven off”. Turns out I did, but we had to drive home to check. I would have loved to pull up an app that told me it was actually off, or even if I was on be able to turn it off from there.
With that said, it’s not worth all the extra bullshit in my opinion.
That’s always a possibility especially when every company under the sun is making smart things on a whim for as cheap as possible. I don’t trust any of them as far as I can throw an oven.
I have a few random smart things, but before I connect them to the internet I make sure they have a decent api that I can use, block external access from the router and set up a little interface so that I can VPN into my home and control stuff if I need to. So in order for anything to be compromised my whole network would have to be owned. Which is still possible but I trust that a lot more than letting 20 different apps for each device have access to anything in my home.
