I own a Xiaomi Vacuum Robot and that is by default very much not local only. However there is a project [1][2] to hack some of those devices and make them local-only.

With limited functionality they work of cause without app and cloud connection.

Thanks for this, I had a pending action item to look for something like this for my robot.

On a spin-off topic from this project: it says on his website

> The Apache-2.0 license is a very permissive license and a lot of work is being shared for free here, so I trust people to not take advantage of that and sell Valetudo; especially not as their own work. Please don’t disappoint me. Thank you.

I really don't understand why people pick licenses that specifically allow for things that they don't want to happen. It's specially baffling when the author is clearly aware of the limitation!

they work locally(local network via app or physical buttons) unless you want to use it remotely via internet. The annoying thing is that it still forces you to "create an account" when you set it up. This was not required 4 years ago but it's required now.
