I'm curious about how smart plugs fundamentally communicate. Do they provide energy control by connecting to the home network via protocols like Wi-Fi, Zigbee, or Bluetooth? What hardware and software layers handle power measurement, scheduling, and remote on/off functions? Additionally, could you provide a general overview of data security and cloud integration? In your opinion, what impact will this technology have on future home automation?
How Do Smart Plugs Work and What Role Do They Play in Home Automation?

I recently set up a Wi‑Fi‑based Sonoff smart plug with my home router, flashed it with Arduino‑based firmware for power metering and scheduling, and now I can control it on/off directly from a mobile app. Using TLS for data encryption and a local MQTT bridge kept the cloud out of the loop, and I’m seeing that future plugs will likely ditch hubs entirely by supporting multi‑protocol stacks like Zigbee/Thread to build more reliable, energy‑centric homes.
