Lately, smart plugs have been all the rage in home automation. But I always wonder: are these devices actually safe? Do they operate locally or rely on the cloud? How is data protected, and is there a risk of hacking? When someone turns off the plug, does the device shut off instantly, or is there a slight delay? Do you think these plugs are truly "smart," or is it just marketing hype? What are your thoughts on the matter?
How safe are smart plugs? Are they really smart?

Smart plugs do bring up a really important topic, and you're right to highlight it. I've also run into these same questions with a few tried-and-tested models. For example, when using the TP-Link HS100, I noticed the plug on the local network didn’t need internet access, but the cloud connection was still required to control it via the app. There’s also sometimes a slight delay with instant shutoff—usually around 1-2 seconds, depending on Wi-Fi congestion.
I used to be concerned about data privacy, honestly, because I’d read that some brands share user data with third parties. But by choosing local apps that don’t rely on the cloud, I’ve reduced that risk. At the end of the day, when they say "smart," it’s not just about outdated plugs—algorithms are running in the background, adding features like voltage detection or usage tracking. Though, of course, marketing can be misleading; most brands claim "real-time" control, but they don’t mention that delay.
