I hacked my washing machine

Summary

How I hacked my washing machine If you've known me for some amount of time you knew this was something that was bound to happen eventually. Yesterday (and technically today), me and a friend went on an endeavor to hack our washing machine, partially for the fun of it, and partially because there's actually a practical use for it. Some background For context, I recently moved into a new house for uni, with some friends. This house was pre-furnished, so it came with all the appliances we needed, including a washing machine and whatnot. And, in true typical renting fashion, the washing machine is some cheap "smart" model, that features a Wi-Fi connection, and a mobile app to control it. Now, half of this house is populated by cybersecurity students, so naturally we were scoffing at the idea of putting the washing machine on the network. And then we did it. Turns out, this washing machine has the capability to send notifications to the mobile app whenever a load finishes. There's also some other stuff too like "self clean" or whatever, but nothing functional (the app is some cheap crappy HTML job crammed into a WebView). This was kinda funny, however, having notifications for when your "three hour" (usually like 4-5 hours) load finishes is actually really useful, especially when you're like me and forgot to... buy clothes, so have to keep the same set of clothes clean constantly. However, only one person can be connected to the washing machine at a time, so if someone else wanted notifications, you'd have to disconnect the washing machine from your app, and then let them do the whole jig. Which involves reconnecting it to the Wi-Fi network, by the way. The front page of the washing machine app, after logging in. The app is called "Hoover Wizard". Notifications received for when a wash cycle finishes. The doorbell Tangentally related, this house is an incredibly old victorian house, meaning the walls, floors, and doors are super thick. There's also only one person living...
