I love smart plugs for two main reasons: automating "dumb" devices and tracking power usage. I’ve plugged my bedside lamps and coffee machine into TP-Link Kasa plugs. In the morning, I don’t have to get up to turn on the kettle—everything’s scheduled through Home Assistant. As for power tracking, I realized my old phone charger, always plugged in, was drawing 5W/h even when off—the plug showed me that right in the app. The "internet dependency" bothers me less now that I’m using Tasmota locally on basic Sonoff devices—no mandatory cloud required.
That said, you gotta be careful with your choice: some cheap plugs send ads through DNS requests (!) or have unstable cloud servers. My advice? Stick to models with open-source firmware (Tasmota/ESPHome) or brands like Shelly/Philips Hue. And if you just want to manually turn something on or off, a regular plug works fine—the smart part is really useful when it’s scheduled or controlled remotely.
I've also tinkered with a few smart plugs while working on small Arduino projects. I actually plugged one into my electric heater, so it turns off automatically when I leave the house—saved me around 20% on my heating bill over the weeks. Sure, it’s annoying that they need to stay connected to Wi-Fi all the time, but when they’re not syncing, they run pretty quietly. All in all, I find them useful, especially since they save me from having to press the power button on certain devices.
Many people see smart plugs as just a "toy" to easily turn lights or fans on and off over the internet, but to me, they're the closest alternative to traditional timer plugs. Old-school timers let you set them to automatically turn on or off at specific times, but smart plugs make this more flexible. For example, you can turn off a heater connected to the plug remotely when you're not working, or simulate someone being home by randomly turning lamps on and off while you're away for security. So instead of just setting a schedule, they "learn" with you. Sure, they rely on a stable Wi-Fi connection and can sometimes be finicky, but I think they're far less limiting than old-school timers, especially when you're away from home. To me, practicality wins over complexity.
They work just like normal outlets, but you can turn them on and off with your phone—simple as that. At their most basic, if you ever forget to turn off your bedside lamp at night, a smart plug will do it for you automatically. It’s not overcomplicated, but I’ve tried it on a few devices and it’s genuinely useful when you need it.
