Smart plugs in home automation can monitor and control energy consumption in real-time, potentially reducing your bills. However, they also raise concerns about external access risks and data privacy, especially with OTA updates exposing security vulnerabilities. What measures do you think should be taken to strike a balance here? Should we prefer open-source firmware or trust certified manufacturers more? Also, how can we effectively measure the impact of smart plugs in energy-saving scenarios? Share your thoughts, buddy 😊
What are your guys' thoughts on the role of smart plugs in energy management and the security concerns they raise?

Smart plugs are a great tool for monitoring energy consumption in real time and remotely turning devices off—something that Turkish users really appreciate. But if we don’t talk about security, these devices become vulnerable to external attacks as soon as they connect to the internet over Wi-Fi. A similar risk appears with smart thermostats (like Nest), where cloud-based OTA updates can introduce vulnerabilities if firmware signing isn’t properly implemented.
To strike the right balance, I recommend a two-pronged approach: first, choose brands that enforce secure boot and signed OTA updates at the hardware level (like the Shelly Plus Plug S); second, customize your own firmware (using open-source platforms like Tasmota or ESPHome) and keep it isolated on a dedicated VLAN. Open-source firmware reduces privacy risks thanks to code transparency and community oversight, and with local control (e.g., via Home Assistant), you can completely prevent data from leaving your network.
In short, picking a trustworthy brand and, when needed, running your own firmware in a closed ecosystem gives you the best balance between energy savings and data security.
