Who is my washing machine talking to¶After tracing the traffic for a short while, I noticed four things:The washing machine REALLY liked talking to... itself? Reverse engineering the washing machine's API¶So, trying to intercept notifications from the washing machine was pretty much out of the question. This was thrown aside since we didn't want to talk to the washing machine, we wanted the washing machine to talk to us. Creating the notification script¶So, by this point, I now haveThe washing machine's API schemaThe washing machine's encryption keyThe ability to poll the washing machineThe ability to decrypt the washing machine's responsesThe ability to read the washing machine's stateNow, I just needed to write a script that would poll the washing machine, and then ping that over to a Discord webhook. The washing machine bot in action, showing the current state of the washing machine.
