We know nothing about the manufacturer's background in this area." I believe the only possible answer is, "Ya think?" Vendors are hot to sell us an Internet of Insecure Things, manufactured as cheaply as possible in countries without a great concern for the privacy rights of citizens in the countries where consumers are being marketed the products. Does this look to anyone else as though it might contain the seeds of (massive, extended) failure? Much as I'd like to control all the lights, washers, dryers, toasters, espresso makers, crockpots, security cams, door locks, garage door openers, and so on from a single (say) tablet interface in my fortress of solitude or comfy chair, I really don't want a socially maladjusted youth in his mom's basement taking that stuff over. I'm willing to continue operating my stuff The Old Fashioned Way until the security issues are worked out. Electric power utilities that have installed "smart" meters, I'm looking at you.
