Wait, in this scenario am I blind & deaf or something? Because I can see my lights turn off when I leave and turn on when I arrive. I can hear and see the lock close when I leave and hear and see it open when I return.
I'm definitely not saying IoT is perfect, but this argument is idiotic. I can also leave my lights on and forget to lock my house with a manual setup, both things I have done before as I'm sure we all have.
Honestly, for a community of users that is entirely focused on tech startups, this is a ludicrous amount of FUD.
