I use the parental controls on the router to put the roomba in grounded-child mode.
That said, I’m not actually positive it works… it is able to connect to home assistant, so it definitely has local network connectivity, but I haven’t proved to myself that it is actually unable to connect to its remote servers since it isn’t really that big of a deal to me.

Your skimming of the article missed how they do indeed talk about the shortcomings of every suggestion they have. For example, the article also does indeed talk about how you can turn off gps but your phone will still ping towers revealing your location, and goes on to say that you can put your phone in a faraday bag but that isnt practical for most people but is indeed an option if you want to do it.
