I was just referring to your comment: > As it stands now I don't care at all who made my Z-wave switches/bulbs/plugs, they could already be out of business for all I care If the company was out of business and there was no way to get the newer firmware, LTT might have had issues. Also, buying a switch because it is advertised as having feature X, only to find out that feature X was added in a newer firmware than you have, and you can't get that firmware. That means it isn't just a "I dont care at all who made my product" scenario. It's much lower risk (especially if the feature you want is basic functionality rather than automation), but it's not 0 risk. I agree with you that Z-wave is going to be 100% better than WiFi devices that call home and join a botnet, but I wanted to make sure it was clear that there is still room for issues.
