I agree. Copy+pasting an old comment of mine from this old thread https://news.ycombinator.com/item?id=12683924

> A general solution to IoT security would be for all IoT devices to only communicate to your personally owned home gateway, which would run open-source drivers for each device to provide the networking/external communication functionality. The IoT device could even be assigned its own isolated network link to the router (i.e. sandboxed).

This is how my home works. My automation devices use Insteon, which is local only communication, and then my computer has an adapter for it that I wrote the software for.

This is a great solution to the ownership problem, but now each individual is responsible for patching and updating their 25 devices? Doesn't solve the security problem.

The home gateway could download the patches and send them to the devices. Its firewall will prevent them to phone home or somewhere else no matter what into those patches.
