Don’t ever trust anyone who sells you a home with smart appliances. This holds true for renting Airbnb’s, vacation homes, or even a friend’s house. There are no guarantees that the people who initially set up smart home appliances aren’t watching you.
Watch the NBC news report in the YouTube video posted above. It explains that you should always erase all former settings in order to safeguard yourself from peeping toms. User names and passwords should always be changed. If you continue using the names and passwords, then you are taking chances.
I’m not being cynical. I’m being practical. Too many people who sell homes, or even landlords who rent, like to check up on their current and former properties. Don’t let anyone intrude on your life. They are breaking the law.
