Folks, the transfer of data between devices in a smart home ecosystem is a hot topic. When it comes to privacy and security, is it healthier to store data on a central server or locally on the network? Also, are current encryption levels sufficient, or should we take additional measures? New standards and protocols are emerging in this field—how do you evaluate these changes? Based on your experiences, which approaches do you think are more sustainable? Share your thoughts and let's discuss!
Also, what are your thoughts on automatic updates and cloud integrations for devices? What measures do you take to reduce the risks of constant connectivity?
How should data privacy be ensured among smart home devices?

Thanks, keeping data local in a smart home (via router VLAN isolation) is generally less risky than relying on the cloud; strong encryption like TLS 1.3 and device-to-device Mutual TLS also boost security. Do you prefer keeping automatic updates within the local network as much as possible and only opening up externally when a critical patch arrives?
Last month, I connected my smart plugs to a local MQTT broker and encrypted them with TLS 1.2—keeping the data on my home network instead of the cloud drastically reduced the risk of leaks. Honestly, restricting automatic updates to only trusted firmware also helped clean things up. I think critical data transfers should always stay on the local network, and adding an extra VPN layer when needed is the most sustainable solution.
