Hey, blog author here. It only had access to the internet for a brief second, and even then it was on an entirely separate network because of how I just set up my openwrt router as a client to the main network. Our guest network is completely isolated, an explicit firewall rule had to be added so that my script could communicate with the washer while it's on this network. It has no access to anything but itself, and occasionally hears the screams of my script demanding it serves up data.
It has access to nothing, only my script has access to it - I don't see a risk here. I still have the heebie jeebies knowing it's connected to anything at all, or even the fact that it can do that, but also spending a night hacking a washing machine was incredibly funny to me and totally worth it. Plus, got some useful notifications out of it.
