The plug you mention above is cloud based:<br>
"use your smartphone to turn off appliances when you're out"<br>
"Accurate feedback: ... whether you're in LAN or remote network"<br>
And the giveaway:<br>
"Double protection and more safety", "LonHand Server"<br>
<br>
That means someone somewhere always knows exactly what you're doing in<br>
your house, whether you're home or not. Assume that this info gets<br>
stored permanently. Assume that this someone eventually gets bought out<br>
by google or likewise, including your personality profile. Orwell would<br>
have a field day.<br>
<br>
As I must have said previously, personally I put this kind of thing into<br>
the class of "consumer junk" with respect to network security.<br>
Irrespective of what big words their marketroids come up with and how<br>
many times they mention "password protected", bugs won't get fixed. The<br>
key is a feel-good instrument if the lock doesn't need it when you look<br>
at it sideways. For wifi I suspect that that unfortunately is a fairly<br>
safe assumption. The firmware is complex and made for time to market and<br>
low cost.<br>
<br>
If you have a good firewall and don't allow these things to connect out<br>
a technically advanced neighbour / passersby may turn your light/fridge<br>
off. You might not care, assuming the thing still "works", which it<br>
might not. It still is a gateway for attacks on your home network<br>
though.<br>
